They didn’t use any real talent for programming. They just used existing hacks that allow OSX to run on generic hardware. Psystar couldn’t even create a way for users to apply system updates or reinstall the OS if anything happened to the hard drive.
The people who wrote the hacks were annoyed that these guys were selling their software even though it was licensed as free software.
If someone wants to build a hackintosh, they should buy a copy of Leopard, then install the hacks themselves. It’s surprisingly straightforward these days.
Well, to be perfectly honest, OSX already runs on generic hardware. It's just a very small subset of available generic hardware for quality control purposes.
Apple just has the OS query the hardware and look for Apple's permission slip. If it's not there, OSX won't run.
The "hacks" simply let the hardware lie to the OS. And it runs fine, provided that the hardware chipsets are the same as on the Apple machine.
