What authorizing your Mac means
Authorizing your Mac for Apple Music means telling Apple that this particular computer is allowed to play music you've purchased or subscribed to. When you sign in with your Apple ID on a Mac, the system doesn't automatically assume every computer with your account should have full access to your library. Authorization is the extra step that unlocks playback.
Think of it like giving a key to a specific house. Your Apple ID is the master key that opens many doors, but authorization is you handing a copy to a particular address. Without it, you might be able to see your music library on the Mac, but the Music app will stop playback after a short preview and ask you to authorize the device.
Apple limits you to authorizing a maximum of five computers at once under a single Apple ID. If you try to authorize a sixth Mac, you'll have to deauthorize one of the others first. This limit exists to prevent widespread sharing of purchased content across many devices.
Key Takeaways
- Authorization happens in the Music app under Account settings and requires your Apple ID password.
- You can authorize up to five Macs per Apple ID, and deauthorizing one frees up a slot for a new device.
- If you forget which Macs are authorized, you can see the full list and manage them from your Apple ID account page online.
- Authorization stays active until you manually deauthorize the Mac or sign out of your Apple ID on that computer.
How to authorize a Mac in the Music app
Open the Music app on your Mac. In the menu bar at the top of the screen, click Music, then select Account. A window will open showing your Apple ID email address and account status.
Look for the button labeled Authorize This Computer. Click it, then enter your Apple ID password when prompted. The system will verify your credentials and authorize the Mac when ready. You should see a confirmation message stating the computer is now authorized.
If the button says Deauthorize This Computer instead, that means the Mac is already authorized. You don't need to do anything else. The authorization will remain active as long as you stay signed in to your Apple ID on this Mac.
What happens if you don't authorize
Without authorization, the Music app will play a 30-second preview of any song in your library, then stop. You'll see a message asking you to authorize the computer. This applies whether you own the songs outright or access them through an Apple Music subscription.
The preview limitation is the app's way of preventing unauthorized playback. It's not a technical error or a sign something is broken—it's intentional protection built into the system. Once you authorize, full playback returns when ready.
Managing authorized computers from your Apple ID account
You can see all your authorized Macs and manage them without being at any of those computers. Go to appleid.apple.com in a web browser and sign in with your Apple ID. Click Devices in the left sidebar, then select Manage your Apple ID if prompted.
The Devices section shows every Mac, iPhone, iPad, and other device linked to your account. Find the Mac you want to deauthorize and click it. You'll see an option to remove it from your account. Deauthorizing from this page works the same as deauthorizing on the Mac itself—it frees up one of your five authorization slots.
This online method is useful if you've sold or given away a Mac and can't access it directly, or if you straightforward want to check which devices are currently authorized without walking to each one.
Deauthorizing a Mac you no longer use
If you're selling, recycling, or giving away a Mac, deauthorize it first. Open the Music app, click Music in the menu bar, then Account. Click the Deauthorize This Computer button and enter your Apple ID password. The Mac is now deauthorized and no longer counts toward your five-device limit.
If you can't access the Mac anymore, use the online method described above. Sign into your Apple ID account on any device with a web browser, go to Devices, and remove the old Mac from the list. Either method works equally well.
Deauthorizing doesn't delete your music or affect your subscription. It straightforward removes that specific computer's permission to play protected content. If you later want to use that Mac again, you can authorize it once more.
Troubleshooting authorization problems
If the Authorize button doesn't appear or you get an error message, first check that you're signed into your Apple ID in System Settings. Go to System Settings (or System Preferences on older Macs), click General, then look for your Apple ID. If you're not signed in, click Sign In and use your credentials.
If you're already signed in but still can't authorize, try signing out and back in. Go to System Settings, find your Apple ID section, and click Sign Out. Then sign back in with your password. After that, open the Music app and try authorizing again.
If you've hit the five-device limit, you'll see a message saying you can't authorize more computers. You must deauthorize one of your existing Macs first. Check your list of authorized devices online and remove one you no longer actively use.
Why authorization exists and how it protects your content
Apple uses authorization to balance two competing needs: letting you use your music on multiple devices while preventing unlimited sharing. Without the five-device limit, one person could authorize dozens of computers in different homes or offices, effectively giving many people access to purchased music they didn't pay for.
The system also protects your Apple Music subscription. If your account is compromised, limiting authorization to five devices means a bad actor can't when ready spread your subscription access across an entire network. You can revoke access by deauthorizing suspicious devices.
Authorization is separate from your subscription status. Canceling Apple Music doesn't automatically deauthorize your Macs, but you'll lose playback rights on all of them once your subscription ends. Reauthorizing won't restore access—you'd need to resubscribe.
Frequently Asked Questions
Can I authorize the same Mac twice?
No. Each Mac can only be authorized once per Apple ID. If you deauthorize it, you can authorize it again later, but you can't have the same computer authorized twice simultaneously. The system recognizes each Mac by its hardware and prevents duplicate authorizations.
What happens if I change my Apple ID password?
Your authorized Macs will continue to play music without interruption. The authorization is tied to your device, not your password. However, if you sign out of your Apple ID on the Mac and sign back in with a new password, you may need to authorize again depending on how the system handles the sign-in.
Do I need to authorize a Mac if I only use Apple Music, not purchased songs?
Yes. Apple Music requires authorization just like purchased music does. Even though you're not buying individual songs, the subscription content is still protected by the same authorization system. Without it, you'll only get 30-second previews.
Can someone else authorize their Mac with my Apple ID?
Technically yes, if they have your Apple ID and password. But this counts toward your five-device limit, so you'd have fewer slots for your own devices. For security, don't share your Apple ID password with others. If you want to share music with family, use Family Sharing instead, which lets each person have their own Apple ID while accessing shared purchases.
What if I authorize a Mac and then forget about it?
The authorization stays active indefinitely until you manually deauthorize it or sign out of your Apple ID on that Mac. If you've lost track of which devices are authorized, check your list online at appleid.apple.com. You can deauthorize old devices from there even if you no longer have physical access to them.
