Hello, I tried to get Darwin 10 (the base of Mac OS X 10.6) running on a PC but i got a kernel panic, because AppleACPIPlatform.kext was not found. AppleACPIPlatform.kext is proprierty and does not legally run on a PC. So I tried to begin writing a new Operating System that runs Mac, Linux and Windows Software. Currently you can compile a Hello world program on Mac OS X 10.5 and run it on Linux using ringo. It is called just PC OS X not Mac OS X or OSx86. Its license is not the APSL with the OSx86 clause.
