Do NOT upgrade until you have made a Time Machine or other backup of your startup drive.
To be clear, software update generally means to install software to update the macOS currently running on the Mac; update Catalina 10.15.1 to Catalina 10.15.7, for example.
A software upgrade is usually a generational step up to a newer macOS; upgrade from 10.13 High Sierra to 10.14 Mojave, for example, or from 10.15 Catalina to macOS 11 Big Sur.
How to Upgrade macOS:
The macOS version you can upgrade to depends on the year your Mac was released.
Click the (Apple) menu at the top left of your screen and choose About This Mac.
❗️ – IMPORTANT – Backup your data, now, before you attempt an upgrade.
