Old Mac won't load AO website or forum

So it's actually a 2014 that I bought on sale in 2015. We're looking at updating it to Monterey as you suggested but it looks like it requires a 3rd party package purchase to do that because it still has the original operating system that it came with on it. How did you go about uploading it for yours? Apple Tech support told me in 2021 that I couldn't update and had to buy a new laptop. I'm seeing that that information must have been false if you worked out an update on yours.
