Earlier today, Apple released version 2.2 of Boot Camp drivers for Windows. Installation requires Boot Camp 2.1 to have been previously installed as well as Service Pack 2 for Windows Vista.

Boot Camp is included with Leopard and Snow Leopard and lets you install Windows on an Intel-based Mac. Shops or individuals who want to go Mac despite an unavoidable Windows-only application should consider Boot Camp along with virtualization options like VMWare and Parallels. For full information on installing Boot Camp as well as upgrade instructions, manuals, troubleshooting tips and more, look here.

Please note that Boot Camp Drivers Update 2.2 is for Mac OS X 10.5 Leopard only.

There are two kinds of people in the Mac world: those who sometimes need Windows, and those who don't. If you're one of the latter group, feel free to skip the rest of this post.

Parallels 5 for Mac has been released, with Snow Leopard compatibility, Windows 7 support, full support for Aero, including Flip 3D in Windows Vista and 7 & OpenGL 2.1 and a host of other new or improved features. You aren't limited to Windows either; Parallels also adds support for OpenGL 2.1 support for Linux guest operating systems. (Although we're a Mac site, I'm glad to see other OSes getting some development attention too.)

It is a free upgrade for those who purchased version 4 on October 1st, 2009 or later. Others will have to pay $49.99USD to upgrade, or $79.99 for a new license.

Parallels is also offering crossgrade licensing to VMware Fusion 2 users. If you have a license key for Fusion 2, you can get Paralells 5 for the same $49.99 upgrade fee as existing Parallels customers.

If you're new to Parallels, check out their introductory video for an overview of how it works.

If you need Windows to go with your Intel Mac, there are a lot of options: Parallels, VMware Fusion (which also recently released a new version), Boot Camp (although Apple isn't yet supporting Windows 7 in Boot Camp), CrossOver, and if you're willing to do a little more "nerd work" to set it up, you can even set up Windows virtualization for free with Sun's VirtualBox tool (well, "free" plus the cost of Windows).

Parallels and VMware Fusion seem destined to be the dueling "favorite flavors" of Windows virtualization on the Mac like Coke vs. Pepsi or vanilla vs. chocolate. Which is the right one for you? Download a demo and take a look. I own both Parallels and VMware Fusion, and look forward to putting them both through their paces with Windows 7.

Thanks to everyone who sent this in.

Update 5:30p: VMware's Pat Lee has acknowledged the problems on the serial-number system and has posted a universal 30-day trial license code and download link to allow users to install the new version.

I never was able to upgrade to a paid version of Fusion 3.0, so I downloaded a demo version and 2.5 hours later received a 30-day serial number.

Installation was trivial, but now I can't find my old version 2.06. That would be bad for people who are trying 3.0 and decide to go back to an older version. I tried a Spotlight search, and my older version is nowhere to be found. That's not good. Has anyone else making the upgrade experienced this? Update: Commenters make it clear that 2.0 will automatically be removed when you move to 3.

I'd already upgraded to Windows 7 on version 2.06, so the same OS came up fine under version 3.0. One of the advantages of 3.0 is that you can assign multiple cores to the app, and since I'm running on a 2 x 2.66 Dual Core Xeon I assigned 2 cores.

Start-up was faster than the old version. About 45 seconds to the Windows 7 desktop, and a few more seconds to bring up a couple of gadgets and settle down. Launch times of apps seem pretty fast, but I don't find the difference dramatic.

Today is release day for VMware Fusion 3.0. The app has more than 50 new enhancements including:

• Support for both 32-bit and 64-bit Snow Leopard kernels.
• Integrated Migration Assistant guides you through migrating from the PC to a virtual machine.
• First virtualization product to support for Windows Aero, including Flip 3D and Aero Peek.
• Support for DirectX 9.0EX with OpenGL 1.4 with new WDDM graphics driver.
• Greatly reduced memory usage when using Windows Vista and Windows 7 virtual machines and newly created Windows XP virtual machines
• Faster disk and graphics performance on Snow Leopard.
• Banish the Start Menu with Always-on Applications Menu on the Mac menu bar.
• Access to Windows taskbar tray items in Unity view in the Mac menu bar.
• Run 3D games and play 1080p video in Unity view.

I started trying to upgrade my copy to 3.0 late last night and into the early morning hours, but the VMware servers insisted I wasn't in the database. I noticed an increasing number of similar complaints on the VMware forums, so I can't tell you about my installation experience, or how it all works with Windows 7.

Stay tuned for more info as we get that sorted out, and hopefully your upgrade experience will be better.

Anil Dash has described how to run Windows 7 on a Mac running OS 10.6 -- as a virtual machine -- for free (after you buy Windows 7, of course). It's not very tricky and, according to Anil, works well. Start by installing Windows 7 in Boot Camp and wait while it grabs the necessary drivers (the duration of this process will vary).

Next, eject the Boot Camp disk and enter a few simple Terminal commands. You'll also need VirtualBox, which is free and open source virtualization software. Once you're done in Terminal, launch VirtualBox and browse to the file you made with Terminal. Read Anil's article for the details.

As today is Windows 7 launch day, we're interested in hearing from anyone who has installed it on their Mac, either via Boot Camp or virtualization.

VMware Fusion 3 features highly improved Snow Leopard support. Most notably, Fusion now sports native 64-bit compatibility and support for the 64-bit kernel. What this means for the average user is improved performance for both the host and guest operating systems.

Further, with support for OpenGL 2.1 and DirectX 9.0c Shader Model 3, gamers will now be able to play more demanding 3D games without the use of Boot Camp. Fusion 3 will also work beautifully with Microsoft's latest operating system by enabling the full Windows 7 experience, side-by-side with your Mac via Unity, complete with Windows Aero and Flip 3D.

VMware Fusion 3 is available for pre-order now and will be on store shelves October 27. Suggested retail price is $79.99US and on the day of launch upgrade pricing of $39.99US will be available for existing customers with previous versions of VMware Fusion.

I use Fusion 2 when I'm at my home office and while the performance has been good, I am really looking forward to Fusion 3's 64-bit support. Any other Fusion users out there, how will you make use of VMware's latest foray into the desktop virtualization game?

VMWare has pushed out another update to Fusion, the popular virtualization app.

Version 2.06 was released yesterday. The 289 MB download includes multiple fixes for running Fusion in a 32-bit Snow Leopard environment. The release includes enhancements for better 3D performance on Macs with Nvidia cards under Snow Leopard.

There are also the usual assortment of other bug fixes.

You can download the update here for free if you're a registered Fusion user. You can get detailed release notes from VMWare at this page. Users who upgrade should note that VMWare Tools does not automatically update when you do the upgrade. You'll have to install the tools from the Fusion menu bar.

When I opened my older version of Fusion this morning I was not alerted to the update, which was a bit of a surprise. Your mileage may vary, so I and am passing the info along to you in case you don't get flagged on it.

Happy downloading.

VMware Fusion has now been updated to version 2.05. The release number is Build 173382. It is a free update to all Fusion 1 and Fusion 2 owners.

The update includes:

• Support for Mac OS X Server guest operating systems with Intel Xeon 5500 and 3500 series processors
• Experimental support for Snow Leopard Server as a guest OS (32 bit only)
• Experimental support for Snow Leopard as a host OS (32 bit only)
• Reduces CPU usage when a VM is idle
• Contains more than 80 bug fixes

I applied the update this morning and had no issues. You can get a look at the release notes here. Your Fusion app should update automatically on launch, or you can download the update from the VMware support web site.

Thanks to Martin for the tip

Serguei Beloussov, CEO of Parallels, was gracious enough to sit down with us to talk about his take on the Keynote, WWDC in general and some enhancements which were announced at the Parallels shindig at Jillian's. The acoustics in the room were very echo-y and I picked up a lot of air noise and fire trucks. The rescued soundtrack has some spooky artifacts but is completely audible.

The direct access we talk about is shown in detail in the Jillian's video linked above, and is a very impressive step forward for virtualization. Continue reading for the video.

Raise your hand if you remember when a Mac was a Mac and a Windows machine was a Windows machine, and never the twain shall meet. I sure do.

Change has come.

Our own Christina Warren has written an exhaustive set of instructions for installing Windows 7 on a Mac over at our sister site, Download Squad. Windows 7 is in beta, so don't try and use it for any mission-critical tasks. Meant to be an incremental update to Vista (Snow Vista?), the current iteration of Windows 7 includes changes like a redesigned taskbar, enhanced touch performance and improvements when run atop multi-core processors.

While Intel Macs can run Windows 7 via Boot Camp, Christina points out that virtualization is probably the best bet for most users. She described how to set up an installation with VMWare Fusion 2.0, Parallels 4.0 and VirtualBox 2.1.2 (and the VMware team has posted a guide of their own for Win7 on Fusion).

If you're a Mac user who keeps Windows around for compatibility testing or that one proprietary Windows app you can't do without, and you're just itching to try Windows 7, this is the tutorial for you. If you're wondering what the fuss is about over on the Microsoft side, Engadget's deep dive on Windows 7 is a good place to start.

In the world of desktop and enterprise virtualization for the Mac, two companies, VMWare and Parallels, top the list. Each offers a suite of products designed to meet the needs of virtualization aficionados -- whether they need to run a rack full of servers or just use Outlook to check email.

At last week's Macworld Expo, TUAW's Michael Rose visited the VMWare booth and spoke with the company's Peter Kazanjy to get all the latest info on their VMWare Fusion product for the Mac and some news that will be of particular interest to those of you wanting to play some cool Windows-only games.

Even though we love our Macs here at TUAW and, if you're reading this site, you probably do to, there's some things you might have to use Windows for occasionally. So, what's a Mac user to do in that situation? Well, most of you probably choose one of the popular virtualization applications available for the Mac to accomplish this.

One of these popular solutions is from a company called Parallels, which recently updated its Parallels Desktop for Mac application. During last week's Macworld Expo, TUAW's Michael Rose visited the Parallels booth to speak with Parallels' CEO Serguei Beloussov and get all the latest on the company's plans for "virtual" domination.

Click through to see what he found out.

Popular virtualization software Parallels has been updated to build 3810. The software offers many upgrades and fixes, including Windows DirectX 9.0 with Shaders Model 2 support, as well as "experimental" support for Snow Leopard and Windows 7 beta.

The "experimental" caution, as you might surmise, means not all features will work. For example, in Snow Leopard, there is no USB support, and Parallels notes there is no shared networking support.

Parallels has been running a competitive race against VMware Fusion as each software solution tries to out-feature and outperform the other.

The Parallels update can be downloaded at this link, or you can select "check for updates" from the Parallels application help menu.

A complete list of the enhancements in this build can be found here. Some users are reporting faster performance and some improvements with use of peripherals.

If you've been considering Parallels Desktop for your two computers, they have a great deal for you: buy one for $80 and get one free. The price effectively gets you two copies of Parallels for $40 each. Not bad. Just follow this link here.

Parallels Desktop is virtualization software that allows you to run a variety of PC operating systems from within Mac OS X.
