Error trying to update macOS Mojave I have the problem shown below when I try the update macOS:



I restarted the computer but I still have the same error. I tried to release the PRAM but it doesn't work. I don't know why I can't update. I try to update from macOS 10.14.6 to 10.14.6. I think maybe is a minor update because I also updated my MBP normally without any problem.
The latest 10.14.6 has sometimes its quirks to install.
I suggest to uncheck "automatically keep my mac up to date".

Download the COMBO update and install it,
