Updating your Mac

As mentioned before, updating your Mac means that you're going to install the new version of your existing operating system. At the moment of writing,Monterey, Ventura and Sonoma are receiving updates. Older versions of macOS don't receive new updates, but after installing a new copy of the macOS, it is reccommended that you check for software updates via App Store> updates for any old and missed software updates to be installed.

To update your Mac, go to system preferences/ system settings> software update to see if there are updates available for your Mac. Important to know is that when your Mac supports the macOS version, it will also support all the updates for that version. So when your Mac can run Monterey (version 12) it can also run the newest release, 12.5.1. When your Mac supports Sonoma, it supports it up to the latest release.
