I was under the impression that since Macs went over to x86, they were capable of running Windows. They are IBM PC compatible.
Once you get past that step a Mac works exactly like a "PC". Just like a "PC" works exactly like a Mac if you fake the EFI-boot via a custom BIOS-to-EFI bootloader on a USB-stick.
There is basically no difference between a modern Mac and a PC - except for Mac OS X, which can be run on "Hackintoshes".
Which is beside the pedantic point, that to be an "IBM PC compatible" you have to NOT run EFI.
I never said that PCs are called PCs because they ARE IBM PC compatible, only said they are called PCs because in the past "IBM PC compatible" defined their category.
Also it's a bit freaky that my disk from 1987 still works in a machine I built last-year. Some games assumed a 4.77MHz clock though, and I there's no turbo button, so they don't really work :(
The PC moniker for Wintel machines, while heralding from the "IBM PC compatible" era, it's used as a designator of the category of, well, PC-derived machines now, not as a technical spec. We mostly use the word Wintel for the respective thing now.
