I’ve just been playing with a very cool piece of software for the Mac. Or is it a piece of software for Windows? Actually, it’s kind of both.
Crossover is based on the work of the WINE project – a curiously-named self-iterative anagram that stands for Wine Is Not an Emulator. WINE has long been used in the Linux community as a means of getting Windows programs to run under Linux. When I first looked at it several years ago it was still very raw and new and difficult to use. However, in the last few years, WINE (and in fact Linux too) has come a very long way. Linux development moves forward at an amazing pace and the last few distributions I looked at were very impressive indeed.
Back to Crossover. Although it’s still only in Public Beta, Crossover runs as an application on either the Mac or Linux platforms and it allows genuine Windows applications to be run natively on either of those OSes. Not emulated. Natively. That means you can take a Windows program and install it on the Mac (or Linux) and have it run as just another application under Mac OSX. It works by translating the API calls of the Windows app directly to the equivalent API calls in the Mac OS, effectively allowing the program to exist in the new OS environment. It’s an incredibly clever piece of software engineering that I think is greatly significant for those of use who don’t want to be restricted in our choice of operating system.
The neat thing is that it truly does run the program under Mac OSX, so the speed of the programs is pretty much the same us it would be under Windows… it’s not an emulation like Parallels, and it doesn’t require a reboot like Boot Camp. It just runs the program in OSX as though it was in Windows. You can copy and paste between the two environments, and the Windows app has full access to the Mac’s file system. The application toolbar resides in the window, just as it would under Windows, while the Mac toolbar shows the Mac as running Crossover… very neat! The installation was very straight forward, and sports a long list of supported Windows apps, including several versions of Photoshop, several versions of Office, plus a bunch of others, including games. You can also try to run other Windows apps, but obviously they can’t test everything. I suppose that’s why it’s still a Public Beta.
It’s kind of weird seeing Windows apps running on my Mac. I don’t really have a need to do it, since there is a Mac program to do do pretty much everything I need to do. I suppose it would be good for software training, as you can effectively use one machine to run an application for whatever platform you need. Other than that, I’m not sure why I’d even want to run a Windows app on my Mac. Still, it’s pretty cool that it can be done, and opens up a whole range of options for those people who would really like to switch, except for that one Windows program that they just can’t live without…
We live in interesting times.
