I have macOs Catalina 10.15.7. How do I upgrade to macOS Sonoma

I have been trying to get the newer macOS Sonoma upgrade on my computer. I have tried going to the App store and have no luck being able to update the OS. Certain web sites say I need a current OS.

Is your iMac a 2019 or later model? That is a requirement for Sonoma. See: How to upgrade to macOS Sonoma - Apple Support

A mid 2014 and late 2014 iMac can be upgraded to the latest version of Big Sur macOS 11 but no later. See: How to download and install macOS - Apple Support
