Hey everyone,


I recently bought a MacBook Pro 15" last week, and have been having some major issues in trying to connect my M-Audio Keystation 49e. It doesn't recognise the midi keyboard when i connect it, and when i go into my audio/ midi drivers there are no drivers listed.


I know the keyboard is in full working order because I've tested it on various other MacBook Pro laptops and it works fine on them.


My operating system in OS X 10.8.2. I've read about others having similar issues with this as well but so far no one has come to with a solution. I also can't even access my MIDI set up as it just gives me an error message. My mac was especially for music production but so far I'm having no luck. I've also tried to download and install various drivers and updates but still no luck.


Could anyone help me please? Literally at the end of my tether!

MacBook Pro (15-inch, Mid 2012), OS X Mountain Lion (10.8.2)

    Two things,


    1) Make sure that you have installed the driver for the keyboard (if necessary)


    2) Check in the Audio MIDI Setup utility (located in the /Applications/Utilities folder) if OSX recognizes this MIDI Device. If not then GarageBand won't see it either.






    Hope that helps

    If the Audio MIDI Setup utility doesn't open, then you have a total different set of problems on your hand.


    Did you try to remove all the exisitng MIDI drivers from the system directory. Maybe some files are corrupted which won't let AMS to open up.


    /Library/Audio/MIDI Devices

    You may have looked in the wrong library.


    There are two libraries, where midi  drivers get installed on a mac:

    • For all users: /Library/Audio/MIDI Devices
    • Your user library: ~/Library/Audio/MIDI Devices


    Your user library (in your Home folder) is hidden by default in Lion or later. You can reveal it from the Finder's "Go" menu:

         Finder > Go

    then hold down the options-key, until "Library" appears in the drop-down menu, select it, to open it in the Finder.






    Added: If you want to reveal the User Library permanently, open a Terminal window and enter:


    chflags nohidden ~/Library
