Comparison Between Genuine Mac & Hackintosh
Is Hackintosh legal?
Sort of. Installing OS X on non-Apple hardware is a violation of the EULA (End User License Agreement), but the general rule is unless you are a business selling Hackintoshes, Apple does not care.
Apple knows we exist and have had plenty of opportunities to stop us, but they have never so much as tried.
Is Hackintosh Stable?
It depends on the machine and the install.
