The usual method is to go to Apple Menu/System Preferences/Software Update, or Apple Menu/System Settings/General/Software Update, and the computer will look for available updates.


This page describes that, and tells what to do with older Macs:

Update macOS on Mac - Apple Support


If your Mac is old enough not to have Software Update in System Settings or System Preferences, it might be helpful on this forum to include your model year and the current operating system.
