I have a late 2012 iMac 21.5" running High Sierra V10.13.6 and would like to know if and how I can update to the latest possible iOS
iMac 21.5″, macOS 10.13
Your 2012 iMac is capable of being upgraded to macOS Catalina 10.15.7.
To upgrade to it, please review the following article: How to upgrade install macOS Catalina safely - OWC
Ref: macOS Catalina is compatible with these computers - Apple Support
A 2012 iMac can run up to macOS 10.15 Catalina. It can not run the latest macOS 11 Big Sur.

Thanks for answering my question... doing Time Machine back up thats taking a long time as I have almost 800 GB to back up.
I think I will do the normal Catalina not the clean up though, Thanks again
