@Mwa@wildbus8979 Yes, early on there was AT&T and Berkley, System-V became AT&T’s mainstream though there were off-shoots like CB-Unix for PDP11/70’s which only had 64k I+D space, and Berkeley had 4.2 and 4.3BSD, and now you have offshoots of those, such as FreeBSD and NETBSD, MacOS is a highly mutilated BSD sitting atop a Mach micro-kernel with the Mac finder sitting on top of the whole mess. The Mach microkernel provides a layer of hardware abstraction that makes it easy to jump between architectures as Mac has often done. What I do not like about MacOS is that they include only drivers necessary for their hardware and forbid the use on Non-Mac’s by license. This limits your selection of things like video cards to those they specifically chose to use.
@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.
Unix also including mac and bsds?

BSDs mostly, Mac wasn’t a Unix based system at the time. It also didn’t run on x86.
