Problem solved.

As you suspected, the iMac vs MacBook Air settings were different. I deselected the VIEW option on the MacBook Air which now matches my iMac setting. Color now remains the same for both locked and unlocked. Seems I need to pause long enough to revisit the OPTIONS again.

Thank you for the quick (and easy) fix.

Hi Scott, you're welcome I'm glad it was solved.

If you want to make sure any other settings are the same you can do that by copying over the moi.ini file from your intel iMac over to your M1 MacBook.

To do that, in Finder click the "Go" menu on the top menu and choose "Go to folder...". In the dialog that pops up, put in:
~/Library/Application Support/Moi

That's where you should find the moi.ini file which is where the settings are stored.

Copy the moi.ini file over to the same location on the new machine.

Thanks, - Michael
