SWsoft, the developers of the Parallels Desktop virtualization software, say that the program has been tested with Mac OS X Leopard, and should be compatible. "We're confident that Parallels Desktop is compatible with Leopard. Performance is great, and core functionality works smoothly," says SWsoft director Ben Rudolph. "You'll be able to safely upgrade to Leopard when it goes live without worrying that Parallels will work." Despite this, the company cautions that it has not actually tried Parallels with the final build of Leopard, which might still generate unexpected errors.
Parallels Desktop costs $80, and is used to run Windows and Linux operating systems alongside the Mac OS without rebooting. Mac OS X 10.4 and an Intel Mac are required. A unique advantage of running Parallels in Leopard is said to be Spaces, which can be used to switch between multiple full-screen operating systems within seconds.
