The "not authorized in your country or region" error for local music you've owned for years is extremely frustrating, but it's usually a licensing "flag" glitch caused by a mismatch in your Apple ID account credentials or a corrupted sync database. Here is how to fix this for your local collection:
1. Re-authorize your Mac Mini — Since this is the "source" of your 20,000 songs, open the Music app on your Mac and go to Account > Authorizations > Authorize This Computer. Even if it was already authorized, doing it again can refresh the local DRM tokens for your files.
2. Verify your Apple ID Region — Go to Settings > [Your Name] > Media & Purchases > View Account > Country/Region. Ensure it is set to your actual location. If this recently changed or was reset, it will block local files that were synced under a different region flag.
3. Sign out and back into Media & Purchases on iPhone — Go to Settings > [Your Name] > Media & Purchases > Sign Out. Restart your iPhone, then tap Media & Purchases > Sign In. This is the most effective way to clear the "region authorization" error on the device itself.
4. Perform a "clean" USB sync —
- Connect your iPhone 13 Pro to your Mac Mini via USB.
- In Finder, select your iPhone and go to the "Music" tab.
- Uncheck "Sync Music" and click Apply. Wait for it to finish (this will remove the greyed-out tracks).
- Re-check "Sync Music" and click Apply. This forces the Mac to re-scan the authorization for all 20,000 tracks and send fresh "keys" to the iPhone.
5. Check for "Matched" songs — If you ever used iTunes Match or Apple Music in the past, some of your local files might have been replaced with "matched" versions from Apple's catalog. These versions *do* have region locks. To fix this, you must ensure you are syncing the original local files from your Mac Mini's hard drive, not cloud versions.
6. Reset Network Settings on iPhone — Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings. This can resolve communication issues between your iPhone and Apple's authorization servers.
Since you've accumulated these shows over a lifetime, they are your personal property. One of these authorization resets should stop the "region" error and let you enjoy your library again!
Hope this helps, John!
