Unknown error occurred (-42408) while syncing itunes to iphone
When I sync my XR Iphone to Itunes via my mac (running majave 10.14.5) I get the message 'iphone cannot be synce. an unknown error occurred (-42408).'
I recently updated to majave 10.14.5 so not sure if this is a problem related to that. A few weeks ago I went to sync my phone to the Mac and it didn't recognize the phone - I had to restore it which is when the music I had loaded to the phone was gone. there are some songs on the phone but not near what I had.
What does this message really mean and how can I get my music back on my phone? Thanks!
