- Find your GarageBand libraries in the default install location. Usually here: /Library/GarageBand/Apple Loops/. Logic also installs the same library, but in a different place, so do a search for it. It places it here: /Library/Logic/GarageBand Library.
- Copy all the folders in /Library -> GarageBand -> Apple Loops to another partition. I usually have a folder ready and waiting called "Samples One" or what ever and put them in there.
- Go back to the /Library -> GarageBand -> Apple Loops folder, and delete the libraries you copied over to your new "Samples" folder.
- VERY IMPORTANT! Delete all the contents in the /Library/GarageBand/Apple Loops Index folder.
- Launch GarageBand. Ignore the "error" messages. Logic users, Logic will automatically use the same libraries as GarageBand, so you can also use this method to have an amazing sample "librarian".
- Drag and drop your new "Samples" folder on to the open GarageBand window. A dialog asking "Move to default location or only index?" Click "ONLY INDEX." This will take a while, but it's worth it. It will also index any and all other samples you have in the same folder. Make sure that in GarageBand's General preferences, you have "Keyword Browsing" set to "off," or it won't show them at all.
Hope this helps!
