Transfer music
My MacBook Air has IOS Catalina installed and I want to transfer a music album from this computer to my wife's iPhone X (updated with version 12.4.1). The internet keeps talking about using iTunes but this has been subsumed into the main system on the new update and I haven't been able to find any instructions on how to do it. Last resort is a local shop next week.
MacBook, OS X 10.11
