Apple used Intel then? Really? Say what?
Intel started in 2006 for a transition to Apple for PowerPC
This is likely a partial reference to the the now forgotten
Star Trek project of 1992 (Marklar is the OS X counterpart of 2002 which was formally announced in 2005)
The tagline was to be "to boldly go where no Mac has gone before" which ComputerWorld (Nov 2/92) mocked with the comment "the OS that boldly goes where everyone else has been"
Star Trek had major problems. It at best could only run on a limited subset of the of the 486 hardware available. If that wasn't enough
every program had to be recoded to run on the OS.
Another issue was the Mac OS was a patchwork spaghetti code mish mach of assemble, Pascal, and C.
When Copland was
the thing the Apple representative stated the reason for the OS was taking so long was that much of the original code had become 'black boxed' and despite simulations showing that a piece of code was never actually called removing it caused the OS to promptly crash.
I had corresponded with Bill Appleton (the maker of World Builder) back in the early 1990s and asked why he didn't update it. He responded that the last version of the compiler had a bug where even if you set it to code 32-bit clean it would still compile 32-bit "dirty". More over past a certain version of the MacOS the compiler itself wouldn't run. So to fix it you had to use ResEdit to hack to code to get the program to run in 32-bit mode.
And World Builder was so well programmed that other then issues caused by the compiler itself (such as sounds not playing on certain models) that the ResEdit patch allowed it to run until Apple stopped supporting Classic.
If that was happening with well written programs when what about the MacOS itself which could be very temperamental? This is likely why emulation programs like Sheepshaver have so many issues: the compilers Apple used were doing things that they technically were not supposed to do and totally bizarre calls are happening.
Microsoft ran into much the same problems with Windows.
