Absolutely Anton, original poster deserves firm correction. Very little broke in either transition; Apple had excellent success with fast and reliable emulation (68K, classic runtime on OS X, PPC on Rosetta). > and OS compatibility by providing essentially a virtual machine > running Mac OS 9 inside Mac OS X (up through 10.4). > > Sadly, Mac OS 9 applications no longer run on Mac OS 10.5, so it's > true that "the world is disrupted" now for those with software > written prior to 2000 or so. I will miss MPW. I wish they would release sources so we could bring it native to OS X. --Toby (Mac user since 1986 or so). > > To make this vaguely Solaris-relevant, it's impressive that SunOS > 4.x applications still generally run on Solaris 10, at least on > SPARC systems, though Sun doesn't do processor emulation.
