Manage the list of devices that can download and play items that you bought with your Apple Account.
You can have ten devices (no more than five computers) associated with your Apple Account for purchases at one time.
Associated devices are not the same as the devices that you’re currently signed in to with your Apple Account. You can find out where you're signed in on your Apple Account page.
Open the Apple Music app or Apple TV app.
From the menu bar on your Mac, choose Account, then choose Account Settings. Or on your Windows PC, click your name at the bottom of the sidebar and then choose View My Account. You might need to sign in to your Apple Account.
Click Manage Linked Devices. If no devices are associated with your Apple Account, this section won't appear.

If your device isn’t on the list and you can’t use it to make purchases, that device might be vintage or obsolete.
If you reach your limit of associations and want to add a new device.
If you can’t redownload purchases from the App Store, Apple TV app, and other Apple services.
If you want to sell or give away an associated device.
Open the Apple Music app or Apple TV app.
From the menu bar on your Mac, choose Account, then choose Account Settings. Or on your Windows PC, click your name at the bottom of the sidebar and then choose View My Account. You might need to sign in to your Apple Account.
Click Manage Linked Devices.
To remove a device, click Remove.
Sign out of your Apple Account on that device and try again. If you still can’t remove it, you might need to wait up to 90 days to associate the device with a different Apple Account.
Open the Settings app.
Tap your name, then tap Media & Purchases.
Tap View Account. You might be asked to sign in.
Scroll down, then tap Remove This Device.
Use the device you would like to add to make a purchase from the App Store, Apple TV app, or another Apple service.
When you try to associate a device that was previously associated, you might notice a message that says, “This device is associated with another Apple Account. You cannot associate this device with another Apple Account for [number] days.” You might need to wait up to 90 days to associate the device with a different Apple Account.
