NeXT Software Inc.'s > OpenStep operating system ran on x86 hardware." I believe NeXT used the Mach 2.5, while OS X uses Mach 3.0. There was a company in Berkeley called Xinu (UNIX spelt backwards), which offered BSD running on either Mach 2.5 or 3.0. They had real problems with Mach 3.0. I am sure Apple has overcome these. NeXT was really loved by those who used it, and OS X appears to be an update of NeXT.
