Live hangs while launching on OSX

  • Live Versions: 8.2.5 - 9
  • Operating System: OS X 10.7 - 10.11


  • Live is unresponsive while launching on Mac OS 10.7 or above and takes 5-10 minutes to start.
  • No MIDI ports listed in Live's preferences → MIDI/Sync tab.
  • This error message might appear: "Company Support Dir not found"
  • Audio/Midi Utility might fail to load the midi window


The most prominent MIDI problem on OSX is caused by a Digidesign MIDI driver which is obviously not fully compatible with later versions of OSX and causes all MIDI applications to hang while trying to initialize this driver. The system's Audio-MIDI-Setup is for example also affected (/Applications/Utilities/).


  • Install the latest Pro Tools 10 update, or:
  • Remove the Digidesign MIDI driver DigiDioMidiDriver.plugin from this folder: Macintosh HD/Library/Audio/MIDI Drivers/
  • Please contact Avid to obtain a compatible MIDI driver for your Pro Tools hardware.

Note: Other outdated MIDI drivers can also cause these issues. If there is no Digidesign driver in the MIDI Driver folder, you can delete any other suspect midi drivers.
