How do I move GarageBand's Lessons and other libraries to another drive?

Solution 1:

  • Quit GarageBand
  • Move /Library/Application\ Support/GarageBand/Learn\ to\ Play/ to another drive
  • Open Terminal
  • Type ln -s followed by a space
  • Drag the folder created in the second step into the Terminal window to insert the path
  • add /Library/Application\ Support/GarageBand/Learn\ to\ Play and press Enter

Test it both the external drive connected and disconnected to be sure GarageBand doesn't have a problem with the LearnToPlay content not being available.
