Update MAC OS 10.15.2 not showing as installed
I have installed the latest MAC OS Catalina Update 10.15.2 5 times from the software update screen of system preferences, each time my mac has restarted and shown it is installing and processing something, however when it restarts and looks for a new update it again says that MAC OS 10.15.2 is available to install.
How do I ensure the update has installed correctly?
