Can my Imac 2011 running Mac OS High Sierra 10.13.6 update to Big Sur? It has not received an update to install it. It also has received notification that iMovie, Keynote and Pages are incompatible because they Require OS X v10.15.

The last security update for High Sierra was back in November.

You can check to see if you received that one by downloading and trying to install it.
Sorry, no one here knows if Apple is going to release more security updates for High Sierra or not.
You would need a 2014 or later iMac to install Big Sur.
No sorry, 10.13 High Sierra is the highest macOS that a 2011 iMac can run.
If you want to run Mojave, Catalina or Big Sur, then you will need to upgrade to a newer or new Mac.
Ok, does that mean I am or no longer receive security updates?
