What is the format of the drive? It should be Mac OS Extended (journaled) with Ownership set to be ignored.

Photos often hangs for me with a spinning beach ball when work with folders and albums. Most often, it hangs almost always when I rename a smart album. This has happened for a very long time, since macOS 10.13 for me. I also migrated to Photos from Aperture, but I have no reason to think that this is the cause. I cannot exclude this possibility either, although the problem is not fixed when I create a new empty Photos library and then populate it by syncing with my iCloud Photos library, which indicates it is a fundamental problem with Photos.

Where is the library located? If on an external HD how is that drive formatted and connected to your Mac?
