The free, open-source software allows Intel- and AMD-based PCs to run several operating systems compatible with the PowerPC, including Mandrake Linux, BSD, Darwin and, most importantly, Apple's Mac OS X.
Users can download and install a copy of PearPC, and then install a boxed copy of OS X, which can be purchased from Apple for $130.
"Installation (of OS X) works beautifully but takes about four hours on a 1300 Athlon," said Weyergraf, referring to a PC with a 1.3GHz AMD Athlon chip. "I must admit 10.3 (OS X Panther) still has problems.... Some program crashes at startup and makes Panther restart it, over and over. We are working on this."
Biallas and Weyergraf warn PearPC is only a version 0.1 release and is still very experimental. By their admission, it is incomplete, unstable and painfully slow -- running about 500 times slower than the host system.
It is "not meant for productive use," the pair caution on the site. "Don't use it on important data, it WILL destroy them sooner or later!"
