Sorry, but MacOS/OSX is a deriviative of NeXTStep, not Tru64.

There is no relationship to Tru64 except that HP did also support OpenSTEP at one point.

From memory, they did swap out Mach from the version 2.5 used in NS/OS for version 3 from MkLinux (which was from OSF). This was at the time of the Rhapsody to OS X transition. My memory is hazy on the BSD kernel mode component history.
