Not "probably", definitely. Objective Pascal, if I remember the name
correctly. Sat in on a Mac programming class at Stanford given by
Andy Hertzfeld. Only the Toolbox was (very highly bummed) 68K assembler.

???? Oh, you're collapsing NeXTstep and Mac OS X, aren't you? The latter
only runs on PowerPC and x64, as far as I know.
According to the book _Mac OS X Internals: A Systems Approach_ by Amit Singh,
there is some very low level assembler code on the PowerPC. I don't know
what might have been done about that on x64.
