Energy Saver 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.

Processor Performance & 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:

  • The PowerPC G5 processor in your Power Mac G5 can run at various speeds. The default setting for this feature is "Automatic", which allows the system to run the processor at full speed when required, and at a lower speed during periods of light processing activity. Certain real-time applications, such as audio creation or gaming, may perform optimally when using the highest processor performance setting. You can change the processor performance setting in the Energy Saver pane of System Preferences.
