Error 50
I keep getting "error 50" appear every time I sync my iPhone or iPad to my Mac, they sync ok, but unable to stop error message every time I sync.
Tried signing out & back into my account on Mac.
Erasing iPhone and restoring by a backup on my Mac.
Never had this before, only since I purchased my new 2019 iMac.
I'd be grateful for any ideas.
Thanks
iMac 21.5″, macOS 10.13
