Follow these steps to install Linux on a Mac using Parallels Desktop. Download a Linux distribution file and save it to your Downloads folder. The file will have an '.iso' extension. Parallels Desktop is a software developed by Parallels Desktop for Mac computers with Intel processors. This was the first software product to make this mainstream using the Apple-Intel architecture.

Despite the Mac's recent gains in market share, Windows is still the dominant operating system, especially in businesses. That means there may be times when you need to run the Microsoft OS: perhaps there’s an application your company uses that’s only available for Windows, or you’re a web developer and you need to test your sites in a true native Windows web browser. Or maybe you want to play computer games that aren’t available for OS X. Whatever your reason for running Windows, there are a number of ways your Mac can do it for you.

If you need to run just one or two specific Windows apps, you may be able to do so using CrossOver (), which can run such applications without requiring you to actually install Windows. (CrossOver's vendor, CodeWeavers, maintains a list of compatible apps.)

If you need a more flexible, full-fledged Windows installation, you still have several other options. You could use Apple’s own Boot Camp, which lets you install Windows on a separate partition of your hard drive. Or you could install one of three third-party virtualization programs: Parallels Desktop 7 (), VMware Fusion (), or VirtualBox (), each of which lets you run Windows (or another operating system) as if it were just another OS X application.

Of those four options, Boot Camp offers the best performance; your Mac is wholly given over to running Windows. But you have to reboot your system to use Boot Camp, so you can’t use it at the same time as OS X; it's Mac or Windows, but not both. And while VirtualBox is free, setting it up is complicated—downright geeky, at times—and it lacks some bells and whistles you might want. Which leaves Parallels Desktop and VMware Fusion as your best alternatives.

So, of those two, how do you decide which one is right for you? In the past, I tried to answer that question by comparing virtualization programs head-to-head, to see how they did on specific tasks. This time, however, that task-based approach didn’t work, largely because (with a couple exceptions that are noted below) the latest versions of Fusion and Parallels Desktop are nearly indistinguishable in performance. So instead of picking one program over the other based on how well it performs a given task, the choice now hinges on some more subjective factors. So this time around, I’ll look at those and try to explain how the two programs differ on each.

Note that, for the most part, I've focused primarily on using these programs to run Windows on your Mac. You can, of course, use them to run other operating systems—including OS X Lion itself—but that’s not the focus here.

General Performance

As noted, both Parallels Desktop and Fusion perform well when it comes to running Windows 7 on a Mac. Macworld Labs ran both programs through PCWorld’s WorldBench 6 benchmark suite, and the results were close: overall, VMware Fusion beat out Parallels Desktop by a very slight margin (113 to 118, meaning Fusion was 18 percent faster than a theoretical baseline system, Parallels Desktop 13 percent). Parallels Desktop was faster than Fusion in some individual tests, Fusion was faster in others, and in the rest the differences were almost too close to call.

WorldBench 6 uses automated test scripts and eight different applications to simulate the real-world use of a system; we run the full suite multiple times then average the results together. For WorldBench scores, higher is better. All other results are in seconds; lower is better. Best result in bold. Tests run on a 2011 17-inch 2.2GHz Quad Core i7 MacBook Pro with 4GB RAM running OS X Lion 10.7.1; both Virtual Machines were configured to use a 200GB drive, 1724MB RAM, and 4 processors

Distill these numbers to their essence, and what you have are two fast, capable ways of running Windows on your Mac.

Advantage: Neither (or both).

Specific types of performance

While the two programs are practically indistinguishable in general usage, there are three specific scenarios in which greater differences emerge.

The first of them: gaming. If you want to run Windows in a virtual machine to play games that you can’t play on a Mac, then you’ll want to use Parallels Desktop 7. In my testing, it handily outperformed Fusion, especially on newer titles. One reason is that Parallels supports up to 1GB of video ram (VRAM), versus only 256MB in Fusion. Parallels Desktop also has better DirectX support; one game I tried looked fine in Parallels using DirectX, but awful in Fusion; switching to OpenGL in Fusion solved that problem, but not all games offer this option.

Overall, Parallels Desktop’s 3D engine seems to work much better for games in Windows than does Fusion’s engine. So if Windows gaming is your thing, Parallels is the one you want to use.

Advantage: Parallels Desktop.

Linux with Accelerated Graphics

The second big difference between the two: Only Parallels includes accelerated 3D graphics in Linux virtual machines, so if you need that, you’ll need to use Parallels.

Advantage: Parallels Desktop.

Virtualization Explorer

The third big difference: If you want to explore operating systems other than Windows, Fusion offers a much broader universe of alternatives. Both programs support “virtual appliances”—dowloadable, pre-configured operating systems, often bundled with specific applications. VMware’s appliance library is huge, with over 1,900 appliances available; Parallels Desktop’ library, on the other hand, contains only 98. (Desktop can use VMware’s appliances, but they must first be converted to the Parallels format; it doesn’t really seem fair to give the program full credit for that capabiity, if it’s reliant on the VMware ecosystem.) So you want to explore the wild world of operating systems and applications, Fusion is the way to go.

Advantage: Fusion.

So much for the three categories with relatively clear winners; now for the more subjective criteria.

Purchase and license

Fusion and Parallels Desktop both normally cost $80, but pricing for both is a moving target. For example, VMware is currently offering Fusion at a promotional price of $50. Meanwhile, Parallels will sell Desktop 7 as an upgrade to owners of older versions for $50; if you’re currently using Fusion, Parallels will sell you Desktop 7 for $30. No matter how much you pay for a virtualization program, remember that you’ll also need to factor in the price of Windows itself.

There’s a big hidden cost in those prices: the software license. Fusion’s license (for non-business users) allows you to install and use it on any Macs that you own or control. Parallels Desktop, on the other hand, requires one license per machine, and it uses activation to check those serial numbers. So if you want to run your virtualization program on more than
