Malarkey. MacOS comes with a Kext called "Don't Steal MacOS", also known as "DSMOS." If it detects you are running on unapproved hardware, it stops your boot and also echos this message to your logs: "Your karma check for today: There once was a user that whined, his existing OS was so blind, he'd do better to pirate an OS that ran great, but found his hardware declined. Please don't steal Mac OS! Really, that's way uncool. (C) Apple Computer, Inc." It's not just a simple detection either, but actually uses encryption to decrypt certain MacOS components after the verification check (namely, Finder, Dock, SystemUIServer, some others). Removing or bypassing DSMOS is required for all Hackintoshing tools, and it's actually a DMCA violation do that (see Apple vs. Psystar). Legally, removing it is the equivalent of removing or disabling Windows Activation, or using a Windows Activation crack tool. The bypass is most often accomplished with the simulated, fake SMC. However, (again) legally, that qualifies as a DMCA circumvention tool by including the specific key that MacOS is looking for.
