If you were considering upgrading you Mac OS X to El Capitan 10.11 I would deeply reconsider that if you are using an Mbox 2 related devices.
Over the last couple of days I've installed OS X El Capitan 10.11 GM Candidate and any updates that were available up to September 23, 2015 on a spare hard drive as I'm apart of the public beta program for El Capitan, and the results are not good if you plan on using your Mbox 2 or related drivers.
My tests were conducted with 10.11 GM Candidate and then updated to 10.11.1 Public Beta 1.
10.3.3 Drivers - Installed fine, all green lights on Mbox 2 device are bright green as if everything is working fine, Both directly connected to USB port and via Hub. The preference pane for the Mbox 2 says it's not connected, and under sound (System Preference) it doesn't show up at all. So there is some sort of connection but it does not register at all and it basically useless at the moment, but maybe Avid can do some investigating and work with Apple to find a resolution to the problem.
10.3.9 Drivers - Installs fine, lights are all dim with really no signs of life. Both directly connected to USB port and via Hub, The preference pane for the Mbox 2 says it's not connected, and under sound (System Preference) it doesn't show up at all. So just like Yosemite this driver is DOA.
So these are the results of testing both drivers, as it stands El Capitan 10.11 is your Mbox 2 Killer, unless someone finds a possible solution.

Maximum Performance Guidelines

  • Recording to the system startup drive is not recommended or supported
  • For Power Mac G5 or G4 desktop models, a separate internal or external dedicated audio hard drive is highly recommended for maximum performance and track count.Although limited recording and playback of audio tracks may be possible using the internal drive in iBook, PowerBook, iMac and Mac mini models, a separate external dedicated audio hard drive is highly recommended for maximum performance and track count. Digidesign recommends the use of FireWire drives for use with these computers.
  • Dual processor users will experience increased performance over single processor CPUs
  • Mbox 2 will not function properly if connected to a passive USB hub. If you need to use a hub for other USB peripherals, use a powered hub or a separate dedicated USB port for Mbox 2 to function properly.

Known Incompatibilities

Digidesign Mbox Driver Windows 10

Digidesign mbox 2 drivers mac
  • Mbox 2 will not function if any Digidesign PCI cards are installed in the CPU. (Digi 001, Audiomedia III, TDM cards, SampleCell)
  • Pro Tools LE core hardware systems cannot be combined
  • Pro Tools does not work in the OS 9 'Classic Mode'. You must choose Mac OS X as your Startup Disk.

New Session File Format ('.ptf')

Pro Tools 7.0 uses a new session file format and extension (.ptf) to distinguish its sessions from sessions created with previous versions. Pro Tools 7 sessions need to be saved as an earlier format to be used with pre-7.0 Pro Tools systems. For more information, see the following:

Energy Saver Settings

Digidesign Mbox 2 Mini Drivers Windows 10

Pro Tools Does Not Support Sleep Mode

Digidesign Mbox 2 Software Download

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.
