Power Mac G5 Pro Tools|HD & Pro Tools|HD Accel Requirements
With Pro Tools HD 7.0/7.1 for Mac OS X 10.4 ("Tiger")
Supported Power Mac G5 PCI Express Computers
These Power Mac G5 PCI Express models require one of the following configurations:
These Power Mac G5 PCI Express models require Pro Tools 7.1 or higher, included with Pro Tools|HD PCIe Core Systems.
All 3 new Power Mac G5 models listed above use PCI Express (PCI-e) slots. Previous Digidesign PCI cards: HD Core card, HD Accel card, HD Process card, Digidesign 64-bit Expansion Chassis, ATTO UL3D, or any hardware that requires PCI or PCI-X slots cannot be installed internally on these G5 PCI Express models. For more information on PCI Express-compatible Pro Tools|HD Core and Pro Tools|HD Accel cards, please see the following announcement in the News section:
Avid Mojo & Apple Power Mac G5 PCIe (PCI Express) Alert
Please see the information farther down on this same page regarding the use of Avid Mojo with Power Mac G5 PCIe (PCI Express) models.
There is a known issue with low hardware buffer sizes and the multiprocessor RTAS engine of Pro Tools 7 (HD, LE, and M-Powered). Specifically at buffer sizes lower than 512, multiprocessor setups of Pro Tools can show a marked INCREASE in CPU utilization as you enable more processors. While dual processor models also exhibit this behavior somewhat, it is more noticeable with 3 or 4 processors enabled on the Power Mac Quad G5.
Digidesign is aware of the problem, and is actively working on the issue. We have run a number of tests, and while we continue to investigate a fix, our tests have turned up a few situations where this problem is likely to manifest, and a workaround for those scenarios.
At buffer sizes 512 and higher, we recommend you use the maximum number of processors. More processors will give you more cycles to run additional RTAS plug-ins and more tracks with little additional overhead from Pro Tools' management of additional processors.
We recommend the following setting for existing or new sessions that require lower buffer sizes:
Once you are mixing, you may use all processors, and restore any inactive tracks/plug-ins. You can then increase the HW buffer size to 512 or higher to prevent errors.
We are fully engaged in this investigation and we will update our customers as we have more information.

Compatibility Alert — Power Mac G5 2.3/2.7GHz Models
Digidesign has identified an intermittent problem with Pro Tools|HD and the following Power Mac G5 2.3GHz and 2.7GHz models (introduced April 27, 2005). At times in a small number of these systems, not all of the cards in a Pro Tools|HD or Pro Tools|HD Accel system are seen by the Mac in Apple System Profiler or DigiTest. During launch, Pro Tools shows "DAE error -1123" or "Flex Cable Error".
This is because the configuration is seen as an extra TDM flex cable attached to the last recognized card, but not connected to the subsequent card. This problem can usually be resolved by restarting the computer. In rare occasions, multiple restarts may be required. If restarting fails to solve the issue described, please contact Digidesign Technical Support for additional troubleshooting and diagnosis.
Not Qualified with Pro Tools|HD and Pro Tools|HD Accel Systems
Dual Processor G5 & 2 GB RAM Required with the following:
Not Tested with Avid Mojo with Pro Tools HD 7
Supported Expansion Chassis
For detailed information, please see the following:
SCSI Accelerator Cards
For maximum track count, Pro Tools|HD systems require the use of a qualified SCSI HBA card. Supported SCSI Cards for the Power Mac G5 models listed at the top of this page:
For more information, please see the following page:
Dual Monitor Graphics Cards
All dual monitor cards which ship as standard equipment with qualified Apple Power Mac G5 models at the top of this page are supported.
Apple Cinema HD Display (30" flat panel)
The Apple 30-inch Cinema HD Display has been qualified by Digidesign with Pro Tools HD 7.0 with the following graphics card:
These graphics cards do not block the adjacent PCI slot, and allow the use of all 3 PCI and PCI-X slots
Not Tested by Digidesign with Apple Cinema HD Display
Apple has qualified the following optional AGP graphics cards for use with the Apple 30-inch Cinema HD Display.
Due to size of the following optional NVIDEA AGP graphics cards qualified by Apple for use with the Apple 30-inch Cinema HD Display, the adjacent PCI or PCI-X slot will be blocked and reduces the number of available PCI or PCI-X slots from three to two:
Maximum Performance Guidelines
Energy Saver Settings for Power Mac G5
For optimal Pro Tools performance, you must set Processor Performance (located in System Preferences > Energy Saver > Options) to "Highest". Updating your Mac OS may reset this to the default setting: "Automatic". After updating your Mac OS, check to make sure this is set to "Highest".
Apple's Mac OS help documentation provides the following info on Energy Saver Processor settings:
Pro Tools Does Not Support Sleep Mode
In the Macintosh System Preferences, launch Energy Saver, click the Sleep tab, and disable all Sleep features. Set "Put the computer to sleep when it is inactive" to Never. Do not manually put your computer to sleep when running Pro Tools.
If your Avid Mojo is not recognized by an Apple Power Mac G5 PCIe (PCI Express) computer, you must update the video peripheral's firmware on another computer. The firmware cannot be updated on the PCIe computer. (This will be true for all Avid Mojo interfaces manufactured before January 2006.) To update the firmware:
Note that using an updated video peripheral with an earlier version of Pro Tools or Media Station software will downgrade the firmware, and the process above will need to be repeated.
AVoption|V10 is only compatible with Windows XP
Incompatible with Power Mac G5 due to 5.0 volt limitation:
Third-Party PCI Cards Incompatible with Power Mac G5
Older versions of the Igniter, IgniterRT, and IgniterLT card are not electronically or physically compatible with the Power Mac G5, as they are 5 volt-only cards. You can tell if your card is compatible by examining the edge connector. If there is only one "slot" in the PCI edge connector, it is the older style 5 volt-only card. For details on how to upgrade to the newer IgniterX card, go to:
Other Digidesign PCI cards are not compatible with Pro Tools|HD Systems or Power Mac G5
Previous Digidesign PCI cards are incompatible with Pro Tools|HD systems. You cannot combine Pro Tools|HD and these PCI cards, either in the CPU or an expansion chassis. Doing so will cause crashes, or the CPU will simply fail to boot. The following Digidesign cards are not compatible with Pro Tools|HD systems for Mac OS X or Power Mac G5:
The following Digidesign hardware is also not compatible with Pro Tools|HD systems:
