I have questions about syncing my iPad & iPhone to my iMac
First, I am not subscribed to Apple Music or to Music Match. The majority of my music tracks have been added by importing CDs to my iMac.
What exactly takes place when you sync an iPhone or iPad to the iMac. Are all of the songs erased from the iPhone then reinstalled from the iMac? If there are songs on the iPhone that are not on the iMac, do they get deleted from the iPhone or do they remain on the iPhone and/or do they get transferred to the iMac?
My iMac is a 3 GHz 6-Core Intel Core i5. The iPhone is an iPhone 13. My iPad is an iPad Air 5th generation.
