Claiming "two brains are better than one," Apple introduced the first dual processor Power Macs since the 9600MP, which had two 200 MHz 604e processors. Although Mac OS 9 has some multiprocessing support, until OS X shipped, only a few applications (such as Photoshop) took advantage of the second processor.

Fortunately for the buyer, Apple added the second G4 processor without raising the price of the Power Mac G4. This meant that anyone buying a "Mystic" G4 would be ready for the multiprocessor enabled OS X.

Because of voltage differences between the AGP 2x and 4x specifications, AGP 4x cards may be electronically incompatible with computers designed for AGP 2x cards, although many cards are designed to work in both 2x and 4x slots. Be sure to check compatibility before purchasing any AGP 4x card for this Power Mac.

Although the Mystic Power Macs support up to 2 GB of RAM, Mac OS 9 is only able to recognize up to 1.5 GB of RAM.

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 (not a CD).

Cautions

Leopard (Mac OS X 10.5) boot times for Power Mac with the GeForce 6200 fall into the 4-5 minute range, and was initially suggested that you install Leopard with the Mac's original video card to avoid slowing down the process. "gotoh" has posted the fix in The Mac Elite Forum. The delay is due to Leopard not supporting temperature sensors in G4 Macs. Simply remove AppleHWSensor.kext from /System/Library/Extensions, and the delay goes away.
Power Macs earlier than the 2002 Quicksilver models do not have built-in support for IDE hard drives with capacities over 128 GB. Without a third-party solution, larger drives can only be formatted to 128 GB in these models. There are three options (as noted on Accelerate Your Mac):
- Intech's ATA Hi-Cap Support Driver
- A PCI IDE card that supports big drives
- A FireWire enclosure that supports big drives
