I have a 2011 27 inch Mac computer and I have macOS High Sierra. I have tried to update my macOS system but getting message saying cannot install on this computer, need help on what I can do?

Buy a newer computer. Mojave and Catalina require an iMac to be at least a 2012 model.

Back up your data, check your applications for compatibility, and click on Catalina.

I don't have the Catalina upgrade option on my iMac either even though About tells me: "(21.5-inch, Late 2012)"

Thoughts?
