So, after I upgraded to macOS High Sierra 10.13, the Photos app updated and iMovie no longer attached it in the Library. What I had to do is to set “Use as system photo library” in the Photos preferences, but it was grayed out. In order to reset this, I had to launch Photos with the option key pushed and a menu will come up, create a new library. After created a new library, open it up go to preferences, set Use as system photo library and the new one shows up in the iMovie. Now, I open the original Photo Library with Photos, go to preferences and the option Use as system photo library available, set it and my old Photo Library appear again in iMovie. Delete the new library.

Issue

Either the iPhoto application is corrupted or it is the iPhoto Library that has corrupted. We can rebuild your iPhoto Library and see if that works or not. Close iPhoto if it is open. Hold down the Command and Option keys on the keyboard and open iPhoto. Keep the keys held down until you are prompted to rebuild the library. Dec 21, 2020 Apple provides a repair tool to address a corrupt Photos library. The repair tool examines the library's database and repairs any conflicts it senses. Depending on the magnitude and size of your library, the whole process could take a bit of time. When the process is done, Photos opens the library again, with your files intact.

Macbook Air (MacOS 10.11 - El Capitan) with empty Photos library cannot download photos from iCloud (previously uploaded by another Macbook). iCloud Photo Library status in Photos > Preferences > iCloud stuck on 'Updating' for over 24 hours.

Restarting computer, pausing iCloud upload, re-creating or repairing Photos database doesn't make any difference.

Resolution

The fix was a bit a bit random... Open System Preferences > iCloud, click Options next to Photos, then without changing anything (providing iCloud Photo Library is already selected) click Done....

As soon as I clicked Done, Photos app immediately started downloading photos from iCloud...
