Photo App is extremely lagging after Sequoia 15.2 upgrade
I upgraded my M1 MacBook Pro from the initial Sequoia version to version 15.2. After the update, the Photo App is extremely lagging in loading photos in full resolution - it takes between 4 and 11 seconds for photos to be loaded in full resolution!
I tried various steps - complete reboot, ran the First Aid on disk, cleared all cached - nothing help. I also tried the reinstallation the OS - this also did not help.
I finally did a full factory reset (wiping the entire disk), a full installation of the OS, reinstalled all of the apps that I had. The Photo App is now back to normal - no lagging in loading photos in full resolution.
I did notice it is the Sonoma OS that got installed after the full reset. I am not going to upgrade OS to Sequoia until Apple fixes the problem.
Did anyone experience the same problem, and how was it resolved?
