TouchID no longer works after upgrading MacBook Pro operating system
Last Updated August 09, 2017
During an upgrade of macOS 10.12.3 to 10.12.4 with TouchID enabled and Symantec Endpoint Protection (SEP) 14 MP1, the enrollment of a fingerprint with TouchID fails. Touch ID also does not work for existing fingerprints. When you uninstall SEP, Touch ID works again as expected.
