The only actual restriction they have is DSMOS. Other than that, the rest of restrictions are just because of their own implementation of things like EFI, etc

The only actual restriction they have is DSMOS. Other than that, the rest of restrictions are just because of their own implementation of things like EFI, etc Just by using the Clover bootloader + FakeSMC.kext (to bypass DSMOS) you can boot... if your system is supported. You can't blame them for not making drivers for everything, taking into account they control the hardware they sell.
