The Photo Library First Aid dialog appears.
3 Do one of the following:
•
To repair the permissions of the les within your Aperture library: Select Repair Permissions.
This option should be used when Aperture can’t access some of the image les within the
database or Aperture is unable to open the library itself. The Repair Permissions option
reviews each le in your Aperture library and sets the read and write access of each le where
appropriate, allowing Aperture to access the les again.
Note: This option does not relocate referenced images whose original image les are oine.
For more information about reconnecting oine images, see Reconnecting Missing or Oine
Referenced Images on page 98.
•
To repair your Aperture library le: Select Repair Database.
This is the rst option you should use if you believe there is something wrong with the
Aperture library other than image le access issues.
•
To rebuild your database from scratch: Select Rebuild Database.
This option should be used as your last measure as it can be time-consuming for large photo
libraries. If you have tried repairing your database, and the issues you are encountering with
your Aperture library still persist, you should use the Rebuild Database option. Aperture
examines the library’s entire database and rebuilds each component until it reconstitutes your
original Aperture library.
4 Depending on your selection, click Repair or Rebuild.
Aperture either xes le permissions within the library or repairs or rebuilds the library, and then
opens the application workspace.
