MacBook Pro M4 Plus: Cannot log into Music or Apple TV

Hi brian,

This is a known issue that can affect Music and Apple TV apps specifically even when your Apple ID is otherwise working fine on other devices. Here are the steps to fix it:

1. Sign out and back in within each app:

- Open Music app → Account menu (top menu bar) → Sign Out, then sign back in

- Open TV app → same process

- This forces a fresh authentication token

2. Check for conflicting Apple ID sessions:

- Go to System Settings → [your name] and make sure your MBP is listed under your devices

- If you see it listed twice, remove one entry and see if that helps

3. Reset the keychain entries for Music/TV:

- Open Keychain Access (Applications → Utilities)

- Search for "iTunes" and "Music" and delete any expired or duplicate entries

- Then try signing into Music/Apple TV again

4. Check Screen Time / Content Restrictions:

- Go to System Settings → Screen Time

- Make sure Content & Privacy Restrictions aren't blocking the Music or TV apps

- This sometimes gets set up accidentally

5. Reset network settings for those apps:

- Quit both apps completely (Cmd+Q)

- Go to ~/Library/Caches/ and delete the com.apple.Music and com.apple.tv cache folders

- Relaunch the apps

6. If nothing works:

- Sign out of your Apple ID completely: System Settings → [your name] → Sign Out

- Restart your Mac

- Sign back in

- This is the nuclear option but resolves most persistent login issues

Try step 1 first as it resolves this in most cases. Let us know if that helps!
