Ive been using Garageband for 6 months and never had issue until a week ago. I'm on current Mac OS and current Garageband. Help! When I go to save my music various audio tracks or files will, when I go to save as, give a "the file "modern guitar01.wav" couldn't be opened. side note it does save some and always saves drum files which are build in GarageBand. Next when I do to open the file various tracks within song will now open and error message is "the file "123.wav" couldn't be found". side note: I use Focusright for my audio interface. I have fooled around with the novice troubleshooting such as restart and saving in various locations. so frustrating. thanks in advance!
