Photos was unable to open the Library (4302)

I've been using a T7 SSD for several years to hold my library. It is formatted OS X Extended. I'm running Sonoma, which is at the same version 14 for many months. Never had a problem until now. Nothing has changed, but today it will not open. I've run Disk First Aid on the T7, but no problems. Is there a Photos library repair tool anywhere? There should be.

MacBook Pro 16″, macOS 14.0

You don't say if you are using iCloud. If so, then the best bet may be to create a new Library and populate it from iCloud. If you need help with that, let us know.


There is a Library repair. Close Photos and re-launch by "option-command-clicking" the app icon, and telling the pop-up dialog to repair. It may take a few minutes. As always, it's good to have a backup of the Library before doing something like this.
