Apple on Tuesday release an update to macOS Mojave. Version 10.14.3 is now available, though Apple’s notes on the update don’t offer much detail. The notes state the following:
This update improves the security, stability, and compatibility of your Mac and includes the following enterprise content: When making a file-sharing connection that uses a valid Kerberos TGT to authenticate, users are no longer prompted to enter credentials.
The 10.14.3 update also includes several security updates.
Before installing the update, it’s a good idea to back up your Mac first. Once that’s done, go to System Preferences > Software Update to run the update. The installation will take several minutes and your Mac will need to restart.
