I’ve just finished playing with MacOSX Tiger (10.4.1) under VMWare! I added a couple of speed tweaks (getting rid of the ACPI kernel module, removing the floppy/USB controllers and setting the VM guest type to Linux->Other) and it works pretty well considering there are no VMWare Tools to speed up graphics or anything.

Luckily my P4 has SSE2/PAE, although it doesn’t have SSE3 to speed things up more.

I even got networking working using the Maxxuss driver, happily surfing away using Safari (Camino and Firefox wouldn’t load due to missing libraries or something).
