I am on Big Sur and my Photos library is on the internal hard drive. The library does not hold the originals. The photos are on an external USB drive which is formatted as Mac OS extended (journaled). The library does not show as the System photo library and I cannot make it the system photo library as it is grayed out.
How do I solve this?
If the option "Use as System Photos Library" is greyed out, it usually means, it is already the System Photos Library.
As a test:
Is there any library in the list marked as System Photos Library? If not, is there any known problem with your external drive - for example, has it been used for Time Machine backups?
