Why are all my photos not on my iCloud? Or rather, why is my Photos Library file so large?
A forum member asked this question a year ago, and the answer doesn't cover all of the question. Why does my macOS Monterey (on my iMac M1) show storage usage for Photos (high) when all of my photos should be on iCloud?
Note that all of my devices are synced to optimize and synced to iCloud.
