About This Mac showing Mojave version 10.14.5 despite updating to 10.14.6 I updated my Mac to 10.14.6 yesterday but About This Mac is showing the version as 10.14.5. What is going on?
Most likely the update isn't installed. Go to System Preferences app → Software Update and check if an update is shown available.

Either the update is not downloaded or is pending installation. For latter, restarting your Mac should take care of installing it.
