Response to: Did Apple learn anything from its past mistakes?

"Putting Unix on top of Mac OS seems backwards to me. I would think that the right way to do it would be to put Mac OS on top of the Mach kernel, along with Unix."


Of course it seems backwards to put UNIX on top of Mac OS. That's why Apple didn't do that. OS X is a real UNIX on the Mach kernel, with a Mac-like GUI stuck on top. If you choose to run Classic (Mac OS 9 running in a virtual machine), which is something many people choose not to do, then it is running on top of Mach, not vice-versa.
