Big Sur won't sync with iPhone 7

[Reader Rabbit]

Ever since I upgraded to Big Sur, I've had problems syncing my iPhone with my iMac desktop. Originally, it seemed that the only thing that wouldn't sync was Contacts, but now nothing will sync. The iMac recognizes the phone and backs it up, but I keep getting the error message that the iPhone failed to sync because the "sync session failed to finish."

I also have an iPad Pro, and it syncs just fine, so I'm wondering if it's just that Big Sur hates older technology.

All the software is up to date on both iPhone and iMac.

1. I have an iPhone 10...

Once every few syncs, maybe once a month, the sync REFUSES to connect wirelessly…I connect with a cable, sync, then everything works flawlessly for a while.

Just throwing it out there to connect with a cable once, and see what happens.

2. I always connect via cable.

No joy.

3. Some recent updates for Big Sur appear to be for connection issues

4. By this, do you mean Monterey?

According to the Software Update thingy on my iMac, that's the next update. (I'm currently on Big Sur 11.6)
