What to do if the App Store gives your Mac the Dreaded Beach Ball

Tackle a hung App Store update in OS X | MacFixIt – CNET Reviews

My Comments

You have that Macintosh computer running with Apple’s App Store as your preferred download spot for programs. But you notice that the Mac is not being its usual self while you are running an App Store update or download. It starts to show that dreaded “beach ball” for ever during the update process while nothing is happening. This means that the App Store client application is hanging and effectively slowing down the rest of your system.

The main problem that can lead to this typically are about the App Store working with corrupted files in its folders as what happens with any computer programs. This encompasses where the installation packages are held after they are downloaded as well as any temporary files that the App Store creates. The folders will exist on the “Macintosh HD” secondary storage location which is the main storage location for all of your Mac’s programs and data.

Here, when you notice this behaviour, you would have to “force-quit” the App Store application. Either this is done by selecting “Force Quit” from the Apple menu or pressing CommandOptionEsc on the keyboard. You could also “force quit” from the Dock by using Option-Right-Click on the unresponsive application’s icon. After you have done this, the Mac should be more stable by now.

Dealing with the corrupted data

Installation package folder

Then you would have to use Finder to clear out the App Store Updates folder which is at Macintosh HD/Library/Updates. This is where the software update or download packages are held by the App Store before being installed. Once you clear this folder out, it means that the App Store application can draw down fresh “known-to-be-good” install packages from the iTunes App Store.

Temporary and “work” files created by the App Store

Another location that you may have to clear out are the App Store Caches. These represent the temporary files that the App Store application creates as it goes about its work.

Here, you run Terminal and type in: “open $TMPDIR../C” to expose the “cache” folders where data that the App Store needs for speedy operation exists. In this window, look for folders that begin with “com.apple.appstore” and remove these folders.

You also go back to Terminal and type in “open $TMPDIR../T” to expose the temporary-file folders. Here, you look for the folders that begin with “com.apple.appstore” and remove them.

The App Store will take longer to start as it re-builds the cache and temporary files with the fresh “known-to-be-good” data.

Permissions fix for the system resources

This is another area that could house corrupt data and could generally affect your Mac’s stability. It is because the information about the permissions required by the applications to use system resources is kept as data on the Macintosh HD.

Here, you use the Disk Utility to do this task. You select the Macintosh HD in this program’s sidebar and click “Repair Permissions” in the “First Aid” tab to start it repairing any corrupt system-permissions data.

Tips to avoid this problem

If you are using a Wi-Fi wireless LAN connection or a mobile-broadband connection, and you intend to do a lengthy App Store update, make sure that you are getting a consistently strong signal from the wireless network. This is because a poor or inconsistent wireless signal could lead to an increased risk of failed downloads.

As well, it may be a good idea to have your MacBook connected to external power while you are doing a lengthy update. This avoids the risk of a failed download occurring because the battery is on the way out.

Here, you could confine the App Store software updates to your home or workplace so you can be sure of a smooth update scenario.

Using a NAS to hold operating-system updates

The current situation

Netgear ReadyNAS

A network-attached storage can come in handy for storing software updates rather than downloading them frequently

Operating system and application developers are now being required to provide updates for their products during the product’s service life and beyond. This is to provide for a computing environment that is performs in an efficient, secure, reliable and optimum manner. The updates may be released at regular intervals such as on a monthly basis or in response to a situation such as the discovery of a bug or security exploit.

New devices

A common situation that happens with most regular and mobile computing devices when a user takes delivery of them is that the user downloads a large data package to bring it up to date. This may be done many times if multiple units running the same platform are purchased.

Many devices

Similarly, a household may have multiple units running the same operating environment and they have to keep these up to date. The typical example of this may be a family with two or three children who are at secondary school. Here, they may have two or three computers for the children to use as well as one computer per adult. This could be brought about with the older child being given a more powerful computer as they enter senior high school or another computer given to the younger children as they start their secondary school.

But the same bandwidth would be used again and again to update each and every device. This may not be a problem for a couple with one device per adult but would be a problem when you are thinking of environments with more than two devices which is fast becoming the norm.

Using a network-attached storage to locally cache updates

Somehow the network-attached storage devices need to be able to support the ability to locally hold updates and patches for operating systems and applications used in computers on a home or small-business network.

The practice is performed frequently with large-business computer setups because of the number of computers being managed in these setups. But it could be practiced with home and small-business setups using a simplified interface. This could be based on the use of a local-storage application for regular or mobile client operating environments which supports this kind of local updating.

A local client application to manage system-update needs

Here, the local-client software could register which operating environment the host computer runs and what eligible applications are on the system so as to prepare an “update manifest” or “shopping list” for the computer. The “shopping list” would be based on the core name of the software, no matter whether different computers are running different variants of the software, such as home laptops running Windows 7 Home Premium while a work-home laptop runs Windows 7 Professional. This manifest would be updated if new applications are installed, existing applications are removed or changed to different editions or the operating system is upgraded to a different version or edition.

A local software manifest held by the NAS

This manifest is then uploaded to the NAS which runs a server application to regularly check the software developers’ update sites for the latest versions and updates for the programs that exist on the “shopping list”. There could be a “commonality” check that assesses whether particular updates and patches apply across older and newer versions of the same software, which can be true for some Windows patches that apply from Windows XP to Windows 7 with the same code.

At regular intervals, the NAS checks for the updates and downloads them as required. Here, it could be feasible to implement logic the check the updates and patches for malware especially as this update path can be an exploit vector. Then the computers that exist on the network check for new software updates and patches at the NAS.

Software requirements

Such a concept could be implemented at the client with most regular and mobile operating systems and could be implemented on network-attached storage devices that work to a platform that allows software addition.

It would also require software developers who develop the operating systems and application software to provide a level of support for update checking by intermediate devices. Initially this could require setups that are particular to a particular developer being installed on the client device and the NAS, but this could move towards one software update solution across many developers.

A change of mindset

What needs to happen is a change of mindset regarding software distribution in the home and small business. Here, the use of local network storage for software updates doesn’t just suit the big business with more than 50 computers in its fleet.

It could suit the household with two or more children in secondary school or a household with many young adults. Similarly a shop that is growing steadily and acquiring a second POS terminal or a medical practice that is setting up for two or more doctors practising concurrently may want this same ability out of their server or NAS.

Conclusion

The NAS shouldn’t just be considered as a storage device but as a way of saving bandwidth when deploying updates in to a household or small business who has multiple computers on the same platform.

Press release

My Comments

DisplayLink have updated their class driver for their USB-based “plug and display” infrastructure in order to satisfy Windows 8’s needs. Primarily this is to benefit tablet computers, convertibles, Ultrabooks and other similar portable Windows 8 computers to allow them to work with larger screens or display-adaptor modules and expose the displays to what Windows 8 can offer.

For example, there is the ability to use both the Start user interface and the regular desktop user interface across the different displays that are linked using this system. Similarly, a manufacturer could offer a touch-enabled monitor-dock that uses this connection interface as a point of innovation and Windows 8 users can still use this touch-enabled screen as a control surface for their portable Windows 8 computer.

It still can work across all USB connection types through the use of data-compression techniques for the common USB 2.0 setup. As well, the adaptors will support a resolution 2560×1152 per screen depending on the bandwidth, which can allow for the new high-pixel-density displays.

What I see of this is that the USB-based expansion modules (docking stations) will still be relevant to the Windows 8 touch-focused computing era as they are with Windows 7 and before.

Touch-enabled Windows 8 computers–where to go

Introduction

I am writing this piece about the newer crop of Windows-8 computers that will be equipped for touchscreen computing. This will explain the different types that will be available and how to get on board this platform.

Types

Portable

Tablet

This class of Windows 8 portable is a simple touch-sensitive tablet that can come with a keyboard and mouse. If you don’t have the keyboard with the computer and you want to do some text entry, these computers will use a touchscreen virtual keyboard for this purpose. Because Windows 8 uses the Bluetooth and USB class drivers for input devices, you can use third-party keyboards and mice that connect via these interface methods. This can come in handy with using the Bluetooth keyboard attachments that are available for iPads and Android tablets.

An extension of this class is Sony’s VAIO Tap 20 which is a 20” tablet that isn’t considered all that portable. Here, this one works with supplied keyboard and mouse accessories but can work as a tablet. It also has a kickstand so it can work like the typical all-in-one computer.

Detachable-keyboard hybrid

These portable computers use a supplied detachable keyboard module that clips to the screen. They take this example from the Android-powered ASUS Transformer Prime and operate in two different forms.

The inexpensive varieties have the keyboard and, in some cases, a trackpad just as a controller device powered by the tablet. But most of the desirable variants would have extra functionality in the detachable keyboard such as an extra battery, USB ports, etc. Here, the computer can benefit from a large range of extra abilities when the user wants to enjoy these benefits.

Convertible

Here, the screen swivels or folds over to become a tablet or the computer can open and close like a regular laptop. An example of this type that I reviewed was the Fujitsu Lifebook TH550M that I previously reviewed and you might be able to claw for cheap on the secondhand market. This is one of the classes of computer that can benefit those of us who want to use the computer for a lot of text entry like working on documents or Excel spreadsheets. Similarly, they can he angled in a manner that benefits viewing or showing content like pictures, PowerPoint presentations, video or Web pages.

The simpler variants fold over so that the keyboard is exposed whereas other types have the screen swivel vertically on a pedestal or horizontally through a frame. These ones may have an increased risk of damage if you try to rotate the screen further in a similar way to what can happen with most digital cameras that have the fold-out screens.

Slider convertible

These computers such as the Sony VAIO Duo 11 appear like a tablet in normal use. But the keyboard on them slides out from underneath the screen and the screen can be tilted up using an integrated kickstand.

Most of them may, at the most, use an integrated thumbstick as the secondary pointing device. Here, you may find that the Bluetooth wireless mouse may be more important for these computers if you want that gradual pointing or scrolling ability that these devices have.

Touch-enabled laptop

The mainstream portable option may simply be a regular clamshell laptop computer that is equipped with a touchscreen. The manufacturers would find this easier to offer as an incremental option for their designs thus offering it across the board.

Most manufacturers are offering as a cheaper alternative a laptop that doesn’t have a touchscreen. Instead these machines use a highly-optimised trackpad that is flush with the palmrest, perhaps with a ridge surround the trackpad. This provides proper support for multi-finger touch operation thus providing some support for Windows 8’s touch gestures. This may be a confusing experience for you if you are working your laptop at one area while you view the screen at another area.

For customers, this could be a cost-effective entry point to the touch-enabled Windows 8 experience for a portable or transportable application.

Desktop

Touch-enabled all-in-one

Most all-in-one Windows desktop computers, like the Sony VAIO J Series that I previously reviewed, will have a touchscreen but Windows 8 and its Metro user interface would make the touchscreen come in to its own on these computers. A few of these computers are gaining respect as far as performance is concerned, thus allowing them to be used for intense gaming, video editing or other intense work.

Regular desktop with touchscreen monitor

Most of us who have regular desktop computers and want to upgrade to Windows 8 could upgrade the monitor to a touch-enabled screen. Similarly a newer regular desktop, whether tower-style or low-profile, could be specified with a touchscreen monitor.

The touch-enabled monitors nay require a USB connection to the host computer as well as the DVI or HDMI video connection.

At the moment, it may be hard to look for a reasonably-priced touchscreen monitor, especially with the preferred DVI, HDMI or DisplayPort sockets. This is because quite a lot of computer retailers, especially the “big-box” retailers, don’t sell them at all or sell them at an exorbitant price. The best result may be to do some online shopping or visit independent computer specialists for these monitors.

Confusing issues

Already own a tablet

If you already own an iPad or Android tablet, you may think that purchasing a touch-enabled Windows computer isn’t necessary. This is even though you may use the iPad or Android tablet with an accessory keyboard to create content.

In some ways, the touch-enabled Windows 8 computer may be a way of extending the touch-driven computing experience you started to enjoy with your mobile-platform-based tablet. Here, you could think of working with a touch-enabled large-screen laptop as a main or sole computer with the tablet serving as a casual-use unit. Similarly equipping the desktop computer for touch computing, whether through purchasing an touch-capable all-in-one or adding a touch-enabled monitor to the existing desktop may achieve this goal.

Similarly, you may own a Windows 7 computer that has an integrated touchscreen or is hooked up to a touchscreen monitor. Here, if the computer is equipped to modern specifications such as a recent-standard processor and at least 2Gb of RAM, preferable at least 4Gb, it may be a good break to update this unit to Windows 8.

Considering a touch-enabled computer less productive

Some of you may find that the touch-enabled computer less productive. This can be so if you expect to enter a lot of text such as working on spreadsheets or preparing copy. It may not be a worry if you just compose short emails or work the Social Web.

These kind of users should place value on a keyboard as being part of the computer and use the touchscreen primarily for navigation and coarse selection purposes. The main screen in Windows 8 does work properly with the touchscreen as do applications that are written ground-up for Windows 8.

The touch-enabled virtual keyboard can come in to its own in a few situations such as entering foreign-language characters, especially those languages with non-Roman alphabets. This can be enabled if you can implement different keyboard layouts for the virtual keyboard and the hardware keyboard. As well, the virtual keyboard can be useful for entering confidential data if you use a desktop computer that you suspect has been equipped with a keystroke-capture hardware “bug”.

Windows RT computers

There are some tablets and detachable-keyboard hybrid computers out there that use ARM processors and run the Windows RT variant of this operating system. One example of this is the Microsoft Surface detachable-keyboard hybrid. These won’t be able to run the software that is currently available for the Windows platform because this software is written to work on the Intel microarchitecture.

Rather, you have to download extra software from the Windows Store which is the integrated app store for the Windows 8 / Windows RT platform. There will be some software like a home-student variant of Office on these computers so you can “get going” with this platform.

Software in the Windows 8 touchscreen world

The iOS and Android mobile operating environments have exposed the world of touchscreen computing to the consumer. This will lead to various expectations for how the user interface will be designed for various classes of program.

A good place to start for finding this software is the Windows Store which is the platform’s app store. As with all app stores, you may find yourself in a situation where you have to sift through the poor-quality “shareware-grade” software to find the good-quality gems. For example, I would start with the official clients for the online services you use or Windows-8 ports of known software titles from known authors.

Web-browsing

This will become a “chrome-free” application with you having to “drag” to the window edge to call up browser functions or the address bar. In Windows 8, there will be some reliance on the Charms Bar which is selected from the right of the screen for some functions like searching.

Office applications

This class of application would benefit from touch, more as a way to locate the cursor to a point in the text or a particular cell or object in the document. You would still use the cursor keys or the mouse for fine-tuning the location of the object.

These applications would have you touch items on the ribbon bars to instigate processes or select options. In some ways, you could see “full-screen” dashboards being used to select options such as creating new documents or applying themes.

Of course, the keyboard and mouse still remain as the tools to remain productive in these applications. Here this would encompass creating the content as well as manipulation parts of the content so you can be sure it looks right.

Gaming

Most game types can benefit from the touch-screen user interface for handling game objects, coarse menu selection or coarse navigation. Some games may exploit the multi-touch option for swivelling or panning the point-of-view or providing “true-to-form” manipulation of objects by allowing the player to turn or grip the object.

Of course there may be issues with slow touchscreens which may impact gameplay with games that require real-time interaction like action, sport or “real-time strategy” games. This would evolve over time as manufacturers create highly-responsive touchscreens that are suited to real-time interaction.

What could happen for most games is to require support for multiple user interfaces such as keyboard, mouse and touch with the ability for the player to determine which interface suits their current gameplay needs.

It is also worth knowing that some existing games may be touch-enabled “out of the box” or through the latest downloadable software patch. For example, Civilization V has been “touch-enabled” through the latest downloaded patch for those of you who have Windows 8.

How to go about buying in to the Windows 8 touchscreen world

I would suggest that you buy in to the Windows 8 touchscreen world as you purchase newer computer hardware. This is more so as more manufacturers introduce this hardware to the market in increasing numbers and at increasingly-different price points.

Convertibles, to some extent sliders, are a good portable solution when you like entering a lot of text as well as wanting to take advantage of the touchscreen as a tablet. The detachable-keyboard hybrid would suit those of us who want the lightweight tablet but like to be ready to do text entry.

If you have the traditional desktop computer as your main computer, whether as the classic “tower” look or a low-profile chassis, I would suggest that you factor the cost of a touch-enabled monitor in to the total upgrade cost for Windows 8. This could be something to evolve to at a later stage as you consider upgrading the monitor. On the other hand, an “all-in-one” desktop can satisfy your needs if you want something more elegant and less cumbersome.

Conclusion

Once Windows 8 gets a stronger foothold, whether through people purchasing new computer equipment or upgrading existing Windows systems to this operating system, touchscreen computing will start to acquire a newer momentum.

Symantec Symposium 2012–My observations from this event

Introduction

Yesterday, I attended the Symantec Symposium 2012 conference which was a chance to demonstrate the computing technologies Symantec was involved in developing and selling that were becoming important to big business computing.

Relevance to this site’s readership

Most solutions exhibited at this conference are pitched at big business with a fleet of 200 or more computers. But there were resellers and IT contractors at this event who buy these large-quantity solutions to sell on to small-business sites who will typically have ten to 100 computers.

I even raised an issue in one of the breakout sessions about how manageability would be assured in a franchised business model such as most fast-food or service-industry chains. Here, this goal could be achieved through the use of thin-client computers or pre-configured equipment bought or leased through the franchisor.

As well, the issues and solution types of the kind shown at this Symposium tend to cross over between small sites and the “big end of town” just like a lot of office technology including the telephone and the fax machine have done so.

Key issues that were being focused were achieving a secure computing environment, supoorting the BYOD device-management model and the trend towards cloud computing for the systems-support tasks.

Secure computing

As part of the Keynote speech, we had a guest speaker from the Australian Federal Police touch on the realities of cybercrime and how it affects the whole of the computing ecosystem. Like what was raised in the previous interview with Alastair MacGibbon and Brahman Thiyagalingham about secure computing in the cloud-computing environment, the kind of people committing cybercrime is now moving towards organised crime like East-European mafia alongside nation states engaging in espionage or sabotage. He also raised that it’s not just regular computers that are at risk, but mobile devices (smartphones and tablets), point-of-sale equipment like EFTPOS terminals and other dedicated-purpose computing devices that are also at risk. He emphasised issues like keeping regular and other computer systems up to date with the latest patches for the operating environment and the application software.

This encompassed the availability of a cloud-driven email and Website verification system that implements a proxy-server setup. This is designed to cater for the real world of business computing where computer equipment is likely to be taken and used out of the office and used with the home network or public networks like hotel or café hotspots. It stays away from the classic site-based corporate firewall and VPN arrangement to provide controlled Internet access for roaming computers. It also was exposing real Internet-usage needs like operating a company’s Social-Web presence, personal Internet services like Internet banking or home monitoring so as to cater for the ever-increasing workday, and the like. Yet this can still allow for an organisation to have control over the resources to prevent cyberslacking or viewing of inappropriate material.

Another technique that I observed is the ability to facilitate two-factor authentication for business resources or customer-facing Websites. This is where the username and password are further protected by something else in the similar way that your bank account is protected at the ATM using your card and your PIN. It was initially achieved through the use of hardware tokens – those key fobs or card-like devices that showed a random number on their display and you had to enter them in your VPN login; or a smart card or SIM that required the use of a hardware reader. Instead Symantec developed a software token that works with most desktop or mobile operating systems and generates this random code. It even exploits integrated hardware security setups in order to make this more robust such as what is part of the Intel Ivy Bridge chipset in second-generation Ultrabooks.

Advanced machine-learning has also played a stronger part in two more secure-computing solutions. For example, there is a risk assessment setup being made available where an environment to fulfill a connection or transaction can be assessed against what is normal for a users’s operating environment and practices. It is similar to the fraud-detection mechanisms that most payment-card companies are implementing where they could detect and alert customers to abnormal transactions that are about to occur, like ANZ Falcon. This can trigger verification requirements for the connection or transaction like the requirement to enter a one-time-password from a software token or an out-of-band voice or SMS confirmation sequence.

The other area where advanced machine-learning plays a role in secure computing is data loss prevention. As we hear of information being leaked out to the press or, at worst, laptops, mobile computing devices and removable storage full of confidential information disappearing and falling in to wrong hands, this field of information security is becoming more important across the board. Here, they used the ability to “fingerprint” confidential data like payment card information and apply handling rules to this information. This includes implementation of on-the-fly encryptions for the data, establishment of secure-access Web portals, and sandboxing of the data. The rules can be applied at different levels and affect the different ways the data is transferred between computers such as shared folders, public-hosted storage services (Dropbox, Evernote, GMail, etc), email (both client-based and Webmail) and removable media (USB memory keys, optical disks). The demonstration focused more on the payment-card numbers but I raised questions regarding information like customer/patient/guest lists or similar reports and this system supports the ability to create the necessary fingerprint of the information to the requirements desired.  

Cloud-focused computing support

The abovementioned secure-computing application makes use of the cloud-computing technology which relies on many of the data centres scattered around the world.

But the Norton 360 online backup solution that is typically packaged with some newer laptops is the basis for cloud-driven data backup. This could support endpoint backup as well as backup for servers, virtual machines and the like.

Mobile computing and BYOD

Symantec have approached the mobile computing and BYOD issues in two different paths. They have catered for the fully-managed devices which may appeal to businesses running fleets of devices that they own or using tablets as interactive customer displays. But they allowed for “object-specific” management where particular objects (apps, files, etc) can be managed or run to particular policies.

It includes the ability to provide a corporate app store with the ability to provide in-house apps, Web links or commercial apps so users know what to “pick up” on their devices. These apps are then set up to run to the policies that affect how that user runs them, including control of data transfer. This setup may also please the big businesses who provide those services that small businesses often provide as an agent or reseller, such as Interflora. Here, they could run the business-specific app store with the line-of-business apps like a flower-delivery-list app that runs on a smartphone. There is the ability to remotely vary and revoke permissions concerning the apps, which could come in handy when the device’s owner walks out of the organisation.

Conclusion

What this conference shows at least is the direction that business computing is taking and was also a chance to see core trends that were affecting this class of computing whether you are at the “big end of town” or not.

Could an upgrade to Windows 8 yield a performance boost to your computer

Installing Windows 8 on your old PC could turn it into Greased Lightning | ZDNet

My Comments

Some of us might think about upgrading an existing computer system to Windows 8 when this operating system is released rather than staying with Windows 7. Most commonly, there would be a lot of doubt about this process but, in some cases, it could improve the computer’s performance.

A Windows computer that was built up in the last four years i.e. since Windows Vista was launched could easily benefit from an upgrade to Windows 8. This is due to the reworked code that is written to work best with the recent generation of hardware.

The speed increase also comes due to natively-integrated desktop security software as well as Internet Explorer 10 and integrated cloud-computing support.

But I would recommend that the system which is being upgraded has current expectations for RAM and secondary-storage capacity. This would be 4Gb RAM and 128Gb of secondary storage as a bare minimum. If the machine uses a hard disk rather than solid-state storage, I would expect it to have at least 320Gb. As I subsequently mention, the operating system is at a price point that may allow you to budget in a hardware upgrade to these expectations.

Users can upgrade their Windows computers to the new operating system at a cost-effective price due mainly to the “electronic hard-copy” distribution that Microsoft is using i.e. to buy and download the operating system online rather than having to buy a packaged copy with an optical disk. This is in a similar way to how Apple are distributing the MacOS X Lion and Mountain Lion operating-system upgrades. It also comes with some attractive licensing terms including the ability for those of us who are building our own systems to legitimately purchase a “system builder” package.

It would be OK to go ahead with the upgrade if you can handle the changes to how the operating environment works, such as the new touch-focused Start “dashboard” and having to “descend further” to get to the standard operating interface. But I would recommend that those of us who aren’t computer-competent should stay with Windows 7 unless they are buying a new computer that comes with Windows 8.

My Comments

You may have just bought the Retina-based MacBook Pro or a Macintosh laptop over the past year but have noticed that you always have to run it on AC power rather than on battery. In some cases, you may have noticed that the fan in the computer is running more than it should.

This has been discovered by Apple as a firmware bug and they have prepared a software update to rectify this problem. This bug is allowing the CPU in the MacBook to run harder than it really needs to, thus allowing it to draw on more power and yield more heat. The software update also improves operating-system compatibility with certain USB devices which may also help with the stability of the system.

This software update is available at Apple’s Website or through the Software Updates panel in MacOS X Lion. Infact, if you have just bought a Mac laptop, I would recommend that you visit the Software Updates option and deploy this and other important updates to your Mac.

My Comments

Owning an older Macintosh computer that is running MacOS X Leopard but isn’t powerful enough to be upgraded to Snow Leopard or Lion? Or you haven’t upgraded your Mac to Snow Leopard or Lion due to keeping a LocalTalk peripheral in service using that link.

You may fear that this situation may make you vulnerable to the recent security scares involving Trojan-Horse programs written in cross-platform code that is targeting the Macintosh platform. Now Apple has remedied that problem by releasing two patches targeting this version of MacOS X.

The Java security update checks for and removes the Flashback Trojan from your Mac, but also disables Safari’s Java plug-in. If you need to use Java in Safari, you would need to visit the Preferences menu by going to Safari>Preferences or pressing [Command] and [,], then clicking the “Enable Java” option.

The Adobe Flash update will disable the out-of-date version of Adobe Flash Player end encourage you to visit Adobe’s Website in order to download the latest version of the software. Here, you make sure that you are downloading for MacOS X 10.4 – 10.5 to get the latest version for your MacOS X Leopard computer.

Microsoft Windows 8 product list now made official–3 product ranges

My Comments

With all of the talk about WIndows 8 coming up this year, there has been a burning question on the variants this operating system will be available in.

The product variants

Windows RT

Firstly, there will be the Windows RT variant which will be delivered with computer equipment based on the ARM microarchitecture. This will have nearly all of the features available for Windows 8 but will have certain limitations to cope with this microarchitecture and what it stands for.

At the moment, users can install Windows 8 “Metro” apps that are compiled and available for the ARM microarchitecture but wouldn’t be able to load and run the typical Windows desktop applications and games compiled for the classic 32-bit / 64-bit x86 microarchitecture. This version will also have an ARM variant of the essential Microsoft Office apps (Word, Excel, PowerPoint & OneNote) onboard.

There will be limited power functionalities with a “Connected Standby” mode as well as the full operational mode, so these devices can keep themselves updated but with the display off and using very little power.

Windows 8

This version is what most home users will head towards and will have most of the features like the Metro touch user-interface, multi-monitor support, ability for users to switch languages amongst other things. It will also have the Windows Media Center functionality for multimedia consumption including TV viewing.

Windows 7 Starter and Home Premium users can upgrade their existing computers to this package of Windows 8.

Windows 8 Pro

This version is pitched at business users and have all of Windows 8’s features except for the Media Center functionality. Instead, it will have the inherent support for volume and file encryption, virtualisation, remote-desktop server functionality and business-class manageability. Of course it will also be pitched at technically-competent home users and they will need to purchase a low-cost “Windows Media Pack” which will have the Windows Media Center functionality if they want this functionality.

Personally, I would also like to see the availability of a “Pro-Plus” package with Windows 8 Pro and the Media Pack targeted at enthusiasts, IT professionals and others who use their computer for work and personal applications.

Conclusion

What I see is that Microsoft has taken the right step with reducing the number of packages available for Windows 8 so they don’t feel as though they have missed out on certain features that are essential for their work and personal computing needs.

Here, I would find that Windows 8 would suit most users while the Pro variant would suit those users with highly-confidential data, a need to link with established business computing environments or want to get more out of their computing environemnt.
