Click on this link to read how to get other versions of macOS - https://support.apple.com/HT211683
- This article also has links to system requirements for each OS version which you should check against your exact computer model. Also make sure you have more RAM than what is noted as "minimum" for any particular system or your computer may run slowly.
- You may find you need to use Safari to get any links using the Mac App Store application to open a functioning page.
Back up your data in case something goes wrong --> Back up your Mac with Time Machine - https://support.apple.com/HT201250 or use a cloning tool.
Check if your old apps will still work with with the OS you want to install - https://roaringapps.com/apps This is particularly critical if you are upgrading to Catalina or newer.
