MacOS 10.14.4 Apple Developer Beta 1, released earlier this week, includes a new tool for MacBook Pro and MacBook Air owners who have a Touch ID. The update allows you to add AutoFill to Safari with your finger for the first time.
Currently, in the Safari Mac application, you can use auto-fill to automatically fill forms, user names, and webpage passwords, including contact information, credit cards, and other forms. You can set the webforms to automatically populate in Preferences in the Safari app.
Once MacOS 10.14.4 is released and if the feature remains (it's still beta), Mac owners with supported devices will be able to use Safari AutoFill by simply tapping the Touch ID reader. The new Touch ID setting is in System preferences at Touch ID,
You can now use the Touch ID for MacOS to unlock your Mac using Apple Pay, as well as make purchases on iTunes and the Mac App Store.
In addition to adding Safari Autofill with Touch ID, MacOS 10.14.4 Developer Beta 1 also includes Apple News for Canadian users. The same feature is available for iOS users in the upcoming iOS 12.2 update.
