iPhoto: Fix media library - how it works

If you can no longer access iPhoto's media library properly, you will need to repair the database. We'll show you how it works.

Repair iPhoto library on Mac

1. Close iPhoto and restart the program while holding the "cmd" and "alt" keys.
2. iPhoto now starts in a help mode. Select the "Repair database" option and click the "Repair" button below.
3. If this does not solve the problem, try the "Repair access rights" and "Re-create thumbnails" options.
4. If that doesn't help either, opt for the "Create new database" option. At the latest now iPhoto should work again.
