The 9600 came in a new case identical to the 8600, but was internally similar to the 9500 that preceded it, with 12 memory slots and 6
PCI expansion card slots instead of the 8 memory and 3 PCI slots on the 8600. The 9600 used the new
PowerPC 604e CPU, an enhanced version of the 9500
604. Like its predecessor, the Power Macintosh 9600 has no built-in video; instead, it shipped with an 8 MB
IXMICRO TwinTurbo 128-bit PCI video card installed. The Power Macintosh 9600/350 was the most powerful Mac ever in Apple's four-digit model numbering system, the last multiprocessor Mac for three years, and the last model with six or more expansion slots until the
2019 Mac Pro. No version of
OS X was officially supported by Apple on the 9600; its installation and use required the use of the third-party software solution XPostFacto.
Mac OS X 10.3 or
10.4 was only possible with a G3 processor upgrade installed, and
OS X 10.5 was possible with a G4 upgrade. The 9600 was part of the final generation of Macs to ship with a
SCSI hard drive as a standard feature; subsequent Macs adopted
IDE for the internal hard drive bus. == Technical specifications ==
