There was also MacMach (<a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;MacMach" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;MacMach</a>), a port of Mach 2.5 (and later 3.0) to the Mac II, and experimental support for running System 7 as a Mach task.<p>Unfortunately the code hasn&#x27;t been available for 20+ years: the license required the user to have an AT&amp;T UNIX source license and a separate agreement with Apple for the Mac task support.
Too bad, it would be fun to play around with today.
