Back up your data, check the application compatibility table, click here, and if your Mac is a 2012 or newer model(2013 for desktop Mac Pros), then on the download link for it.


Catalina and above won't run 32-bit software; use Go64 as well.

Which upgrades—Apple calls bigger and potentially app-breaking changes upgrades, and smaller changes are called updates—are available depends on the Mac model and Mac model year.


Here is: How to download and install macOS - Apple Support


If you want us to check which upgrades are available, post the Mac model and Mac model year from the Apple > About This Mac… menu item.
