iMac 2017 sync stuck, photos/music not syncing with iPhone.
I’m having issues with my iMac 27 inch 2017 5K retina display syncing with various models of iPhones from iPhone 12 Pro Max 512gb up to iPhone 17 Pro Max one tb using finder. My iPhoto albums do not sync fully and of the photos that do sync some are in the wrong albums on my phone, my personal saved music does not upload fully ( sync library is unchecked on both my iMac and phones). My movies and tv shows don’t show up on my phone. Lastly while syncing the progress gets hung up on the last step for hours. I’ve used high-speed cables through my thunderbolt port. I’ve fully restored my iPhones, I’ve turned both the computer and iPhones off and restarted them, I’ve also done a repair library function, none of which corrected my issue.
