Thank you for the reply. I attempted to use Music to authenticate my new MacBook. I was taken right to a screen sign up for paid subscription. Maybe this is new for the latest Macs, or am I doing something wrong? Far as I can tell, if I want to play my own (not iTunes purchased) music files, I will use the free included QuickTime on the new MacBook. Music (the app) on my machine is a paid listen to, or purchase music app that has replaced iTunes. I still can get to iTunes and play purchases on my old iPad, but from what have I experienced, there is no way to authenticate my new Mac to play my transfers from that old iPad unless I pay for a Music (app) subscription, unless I am missing something here. If you know the procedure to authenticate a Mac for iTunes via Music app without paying for a Music subscription, please post. My goal is authentication to get to my old purchases. Itunes is no more for my MacBook and instructions say that Musci app is the way. Thank you.
