Technical information

you boot the computer in OS 9 when installing or using Pro Tools.
● The 2001 and 2002 "Quicksilver" G4 models require OS 9.2, 9.2.1, or 9.2.2 to run Pro
Tools. Users should not attempt to install OS 9.1, or run OSX, (including Classic mode),
with Pro Tools on these machines.
● The Quicksilver G4 models have been tested with the Mac OS as shippped from Apple on
these machines, with a dual boot system which includes both OS 9.2.x and OS X. On
these dual-boot systems, it is absolutely necessary to boot from OS 9.2.x in order to run
Pro Tools. Although you cannot use Pro Tools with OS X or in "Classic" mode
under OS X, it is not necessary to remove OS X from these "Quicksilver" G4
computers.
● Pre-Quicksilver models did not ship with a dual-boot system of OS 9 and OS X pre-
installed by Apple. If you do choose to install OS X in order to create a dual-boot
system, you should not install OS X on the same partition or hard drive with Mac
OS 9.x that you use as your startup drive for Pro Tools on pre-Quicksilver G4
models.
● Whenever updating any operating system, particularly if you are updating Mac OS X for
use with other applications, it is recommended that you remove any plug-in key disk
authorizations and store them on the floppy disk before upating or installing the Mac OS.
After updating the OS, you can then re-install the key disk authorizations after first
booting in OS 9
USB Hubs
The Mbox should be connected using a standard USB cable (included) directly to the computer's
built-in USB port. Connection of the Mbox to a USB hub or USB port on the computer keyboard
is not supported.
Dual Processor G4 Models
Although Mbox and Pro Tools LE are supported on Dual processor G4 models, Pro Tools currently
does not utilize the second processor in Apple Dual Processor CPUs. If problems (such as -6042
errors) occur when using Pro Tools on a Dual Processor CPU, Digidesign recommends the
following: Move the folder named "Multiprocessing" from the System Folder "Extensions" folder
to the "Extensions (Disabled)" folder and restart.
Power Macintosh G4 version history and specifications are also available at www.everymac.com
and www.applespec.com
Incompatibility with older SampleCell II Cards
While SampleCell II Plus cards are compatible with Mbox, older SampleCell II PCI cards may
require a chip upgrade
.
