If you don't see your loops in the Loop Browser, use these steps:
- In the Finder, hold the Option key then choose Go > Library.
- Open Logic Pro 9, Logic Express 9, or GarageBand 6, then open the Loop Browser.
- Drag the folder named "Apple Loops" from the Audio folder in the Finder onto the Loop Browser.
These steps reindex the selected loops. After reindexing is finished, your loops should appear in the Loop Browser.
