Choose Start, point to All Programs, and then choose Windows Update. Do any of the following: If updates need to be installed, choose Install updates. To start checking for updates, choose Check for updates. For more information, choose View available updates. Download Updates Manually.

From the Apple menu in the corner of your screen, choose About This Mac. You should see the macOS name, such as macOS Mojave, followed by its version number. If you need to know the build number as well, click the version number to see it.
Which macOS version is the latest?
These are all Mac operating systems, starting with the most recent. When a major new macOS is released, it gets a new name, such as macOS Big Sur. As updates that change the macOS version number become available, this article is updated to show the latest version of that macOS.
If your Mac is using an earlier version of any Mac operating system, you should install the latest Apple software updates, which can include important security updates and updates for the apps that are installed by macOS, such as Safari, Books, Messages, Mail, Music, Calendar, and Photos.

Reset manual settings (?? all I know is the Apple guy told me to restart the computer holding Command, Option, P and R I think)
Repaired permissions
Repaired disk (worked somewhat because it showed me the available updates but when I went to download them they said the server was unreachable and when I re-opened Software Update the updates were no longer visible)
Does anyone have any other brilliant ideas???
THANKS!
PS: The last successful update was on March 20 2010 with Safari 4.0.5 and a Digital Camera update.
