Power Mac G4

Power Mac G4/466, 533, 667, 733

(Digital Audio)

Overview

Apple doesn't make it easy - this is the third computer to bear the name Power Mac G4. What most differentiates this from earlier models is the 133 MHz motherboard with four PCI slots plus an AGP slot, one more PCI slot than previous models.

There are some differences between the 466/533 models and 667/733 models, making it possible that swapping a CPU designed for one of these models may not work with the other model. We have reports that the 733 MHz CPU does work with the slower model.

With processor speeds ranging from 466 to 733 MHz, the G4 had the power to take on any Pentium 4 machine made at the time. It was also ready for OS X.

At least one version of OS X reports the dual 533 MHz Digital Audio Power Mac as a dual 933 MHz G4 (11.3). There never was a 933 MHz dual G4 from Apple.

Note that we have received just one field report of someone trying to run Mac OS X 10.5 'Leopard' on the dual 533 MHz model but seeing failure. We have received several reports in the affirmative, so we can say that this is notnormative for dual 533 MHz Digital Audio Power Macs.

You should have the most recent firmware installed in your Power Mac G4. The newest version for this Power Mac is Power Mac G4 Firmware Update 4.2.8, which is only for Sawtooth, Gigabit Ethernet, and Digital Audio Power Macs. To install this firmware update, you must boot into Mac OS 9.1-9.2.2 from a writable partition
