Copying music from Mac to iPhone
I want to add music in my Mac library to my iPhone. I don't want to subscribe to any Apple music service. At one time, one could simply drag a song or album to the iphone icon. Or somehow synch music. Now it looks like you can't. How do I do it? I'm using a 2071 Mac Pro running Big Sur 11.4.
iMac 27″, macOS 10.15
