Photos and Albums on iMac not syncing properly -- Big Sur issue?
I access Photos on my iMac, (27", Late 2014, Big Sur 11.6.2 -- not eligible g for OS Monterey) ) MacBook (now running OS Monterey), iPhone and iPad (iOS 15.2). All are connected to the same iCloud account, which I use for photo storage, and have purchased more than enough storage capacity. On my 1TB iMac I have settings set to keep originals on the iMac. On the other devices I have selected optimization using iCloud.
A week ago I created a new album of 30 images on the iMac. A few days later I noticed that while the new album appeared on my other devices, it had just 16 of the 30 images. I looked in the "All Photos" for each device and saw that the images appeared there; they just do not appear in the album.
I have also noticed that sometimes images created with the iPhone or iPad do not show up on my iMac, although they do appear on my other devices.
I have tried a variety of fixes with my iMac: Forced Quits of the Photos app; restarted the iMac: shut down and restarted the iMac; ran the Library Repair tool a few times; Went to Photos > Preferences > iCloud, and unchecked and then checked the "iCloud Photos" box. Nothing has fixed the problem.
As a test I did four things to see if the issue might be with one of the other devices:
- on my iMac I created a small album of 10 images. The new album and all images appear in iCloud Photos accessed via the web, on my iPhone and iPad, but NOT on the iMac (even a full day later.)
2. I created two new albums of 10 images on the iMac. Initially, they did not appear in iCloud (via the web) or any of my other devices. Then today, when I checked in iCloud Photos accessed via the web, both of the albums were there but they are empty. Now, the albums are filled with the images and they also appear on the other devices. [So, is this fixed or just chance?]
3 & 4. I created a new album on my iPhone and a new album on my iPad. They both synced to iCloud and appeared on my MacBook and the other iOS device. As of this moment, however, those two iOs created albums have not appeared in Photos on my iMac, despite my quitting Photos and re-opening it a couple of times.
Thoughts? Solutions? Is this an issue with my iMac or (more likely?) a Big Sur issue?
Thanks.
