There are three ways to do this:
1) Use the Unix version, you'll need a X server installed of course, plus
you would need to build a VM. http://mrcla.com/XonX/ Once I get my CD's I'll
look into building a VM.
2) Marcel Weiher marcel at metaobject.com has a Cocoa version at
This of course is the optimum choice.
3) I've a carbonized version lurking somewhere, I'm waiting my public OS-X
beta to arrive and some further work is required for sound and serial
What does Unix buy? Well Squeak is less affected by other processes running.
right now when you surrender control to Mac OS 9 you don't get it back for 1
millisecond to 1000+ This impacts how smooth Squeak runs. File I/O, paging
should better. Having that Microsoft program crash won't zap Squeak. Memory
allocation is quite different and you don't run into those problems of
running out of memory when Squeak is running plugins that become too greedy
about their memory allocations.
