No. For that Mac, Big Sur is the end of the line.


If your iMac is not running Big Sur yet, you can get it from here:

Note that Catalina and Big Sur will not run 32-bit applications. If you're on Mojave or earlier, you may want to check which of your applications are 32-bit (and will need updating/replacing) before upgrading.

Just to add


If upgrading to macOS 11 Big Sur


Suggest having at least 50 GB of Empty Space on the drive.


It will allow the Full Version ( about 12.xx GB ) to download, then expand and then commence to install.


If there is Third Party Security Software installed - remove it.


It will interfere with both the download and installation process.


Always Make a Time Machine Backup  before doing any upDates / upGrades
