I am trying to update my Mac OS Mojave which is currently running 10.14.3. Now the latest update is 10.14.6. I tried updating via system preferences but it gave me an error "This volume doesn't meet the requirements". I tried downloading and installing combo update from here: https://support.apple.com/kb/DL2010?locale=en_US It gives me error "The package has an invalid signature" on installation while installing after restart. I tried downloading and installing 10.14.4, but it gives the same error "The package has an invalid signature" during installation.
I have been stuck here for days. I really want to update my mac. Please help.

My security and privacy pane is also not loading. Can the update installation have something to do with it?
