Default Re: General Troubleshooting - Pro Tools LE and HD on Mac OS X

If you are experiencing problems with MIDI in Pro Tools (or any other application) where you cannot get input or output, OR your MIDI interface is greyed out in Audio MIDI Setup, try this:

Go to MacHD>Users>your account>Library>Preferences>By Host and trash ' bunch of numbers and letters.plist'.

Go to MacHD>Users>your account>Library>Preferences and trash ''.

Empty the trash and restart, then see if everything is working.
