Not quite, at least if you're going to include every point release and all OS X versions. Sheepshaver poops out at 9.04 (9.1 and later require an MMU which Sheepshaver doesn't emulate), and obviously the Intel Mac isn't going to run anything prior to OS X 10.4. (And there you actually run into another problem: is there an Intel Mac that shipped with 10.4 that'll go all the way to 10.10? Looks like *maybe* the 2007 iMacs might fit the bill?) I suppose there was that "PearPC" emulator, you might be able to run *some* of the PPC-only OS X builds on that.

In any case that's an even bigger cheat than the vFat-capable DOS thing the guy did in the Windows video, of course. Might as well make a video where you start with an ENIAC emulator and "upgrade" yourself through the entire history of electronic digital computers since 1945. There are emulators for a quite a few famous mainframes and minicomputers out there...
