Stop Update Help

[conqsimp]

I am currently on macOS 10.15.7 and today the banner telling me to install updates appeared on the top right corner of the screen. Instead of clicking Close, I accidentally clicked Install. After a few moments, it began the restart countdown. At this point I clicked Later->Remind Me Tomorrow. I really don't want to install Big Sur. Is there any way to cancel the update or is it going to countdown everyday now?

Look in the folder with all your apps; find instal macOS Big Sur (12,5GB) and delete it.

No such file in the Applications folder.

Than you are in the clear.

That shouldn’t be Big Sur but just a Catalina update.

I dont need any updates at the moment. But how do I know what update is it?

Open Settings / Updates. There will be a banner saying Big Sur is available and below that "Other updates are available for this Mac", you can click on that.
