Live hangs while launching due to outdated MIDI drivers (Mac)
- Live Versions: 8.2.5 - 10
- Operating System: OS X 10.7 and higher
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/).
In this case, you will notice the following problems:
- 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
These are the steps to take in order to solve this issue:
- 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Note: Other outdated MIDI drivers can also cause these issues.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.
