You can upgrade to your iMac 20110 to MacOS High Sierra.


High Sierra is as far as you can upgrade to, your mac does not meet the hardware requirements for

macOS Mojave or macOS Catalina.


Please use Safari to access the following links do not use Firefox


How to upgrade to macOS High Sierra - Apple Support


Before upgrading make a full back up of your Mac.


Check that third party apps you use have updates available for the new OS.

https://roaringapps.com

Check that your printers/ scanners etc have updated drivers and software available for the new OS.


Connect your mac to your router via cable rather than rely on WiFi.

Do not use your mac while it is downloading

and do not use any other devices that share the same internet connection.


If the App Store says Open then it is detecting a previous download of the install app

go to the Applications folder locate Install macOS High Sierra.app.

Move it to the Trash, empty the Trash.

Restart, click on the link again, the App Store should say 'get' or 'Download'.
