Although the new MacBook Air and MacBook Pro officially support Touch ID authorization of both App Store and iTunes purchases, setting it up can be a bit of a process. When you're having trouble, check out these troubleshooting ideas for macOS Big Sur.
Troubleshooting Mac: First — Check your software

- Click on the Apple icon in the upper left corner of your Mac.
Select About this Mac. You should see macOS Big Sur with the version number under it. If you are running an older version of macOS, update it now.

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