Manage Your Applications
You can actually use Touch ID as a way to control and manage apps on your Mac. With Touch ID, you can confirm that you want to delete an app and also confirm that you want to install it on your Mac. This way, you don’t have to enter your password every time you install an app, which is especially nice when you get a new Mac.
It’s not just about buying and downloading apps; you can also use Touch ID to download books or other media from Apple Books or the iTunes Store, respectively.
