When I try to get Big Sur from the App store, System preferences launches Software Update and I get an "Update not found".
2017 27" iMac. Everything up to date. I rebooted.
No Clue. Is this possible a firewall thing?
iMac 27″ 5K, macOS 10.15
Thanks. After discovering that EtreCheck was also blocked from loading, I contacted Duke's computer support. Turns out they snuck and put all manner of spyware on my machine and they're blocking Big Sur for now. They say they have to check it out first. They never told us this was happening so I'm kind of ******. Wasted a bunch of time on this.
Thanks again for your help.

You can save both you and us a lot of time and effort if you do the following:

Maybe. I'm at a University and they have installed some stuff on this machine. Not sure what it is or how to turn it off. Can I boot and by-pass whatever is on this machine? Like one of those Ctl-C things.
Do you have any third party antivirus, cleaning or any other maintenance utilities installed on the computer?
Can't get Big Sur
