Apple Music setup

One time only. In your Apple Developer account (developer.apple.com in Safari works fine):

1. Identifiers → + → Media IDs. Description “Chart Run Drive”, identifier media.com.chasfortescue.chartrundrive, check MusicKit, then Register.
2. Keys → +. Name it “Chart Run Drive”, check Media Services (MusicKit…), tap Configure, pick the Media ID, then Save, Continue, Register.
3. Download the key file (AuthKey_….p8). Apple only lets you download it once. Note the Key ID.

The key is read on this phone to make a token that lasts 6 months. It isn’t saved or sent anywhere.
