Stuck at this alert: "An internet connection is required to verify this startup disk"

Just migrated data from a 2011 iMac to a 2020 iMac. All seemed to go smoothly till restart - now I am stuck at this alert - "An internet connection is required to verify this startup disk". When newer Mac is connected to WiFi this message appears when it is trying to start up, and restarting attempts bring this alert up repeatedly. If connected to ethernet it automatically and repeatedly tries and fails to restart without the alert coming up.

Signed,

Frustrated and Desperate

iMac (2017 – 2020)

Hi,

Your iMac 2020 has T2 chip which is caused the problem. You'd better install macOS from the scratch.

Mac computers with the Apple T2 Security Chip – Apple Support (AU)

Hello again. I have gone to recovery mode, clicked the reinstall macOS, the install progress page completed, but it is now showing a "Transferring Your Information" window with a blue line bouncing back and forth - and it hasn't changed for several hours. Any input? There is a cancel option, but not sure what to do.

Thanks again.

Thank you very much for the reply. The only options available in this stuck state are Restart and Shut Down, so I don't know how to accomplish that. Will I need to go into recovery mode?

Managed to get in to recovery mode, and see the reinstall macOS option - do you believe that will fix the problem?

Thanks.
