Basically the title
BSDs mostly, Mac wasn’t a Unix based system at the time. It also didn’t run on x86.
@wildbus8979 @Mwa MacOS was Unix based after Steve Jobs created the Mach/Unix/Mac Finder stack for use on the Next computer, as soon as he returned to Apple, it was adopted there.
I know. At the time of the ACPI debacle, Mac OS X didn’t exist yet, and NeXT was essentially irrelevant because a) it didn’t run x86 and b) it only ran on proprietary hardware.
@wildbus8979 Actually, because it used a Mach microkernel, it could easily be ported to ANY hardware, that is the whole entire point of Mach. Also it did run on the Mc680x0 family and that was what Mac was based upon at the time, prior to Power PC chips, prior to Intel, prior to M chips, and it is precisely that Mach microkernel that enabled the easy transition from one hardware platform to the next.
