Updating OS to a previous version
I need to update to Big Sur from Catalina. Is this possible?
Then click on the link Niel posted and select Big Sur.

You need one of these Macs to install Big Sur.
macOS Big Sur is compatible with these computers - Apple Support
Back up your data, check the application compatibility table, click here, and if your Mac model is recent enough, then on the download link for it.

Yes, I have iMac 2019. I am having trouble with Adobe creative cloud apps now, but don't want Monterey or Ventura as I lose QB 2019 desktop for mac.
Love that compatability table! Thank you.
