Troubleshooting iTunes and App Store purchases on Macs with Touch ID

The item you've chosen will begin to download; afterward, you'll be able to use Touch ID for all future purchases in that app.

The iTunes Store and Mac App Store have separate Touch ID authorizations, so you'll need to repeat steps 7 - 10 in the other app if you'd like to use Touch ID in both stores.

Troubleshooting Mac: Third — Give permission to use Touch ID to make purchases for iTunes and the Mac App Store

1. Visit iTunes or the Mac App Store apps and navigate to an item you'd like to download.
2. Press the Buy button on an app or song you'd like to download.
3. Scan your fingerprint on your Mac's Touch ID sensor when prompted.
