Mojave to Big Sur and back

[garmp]

I upgraded my iMac from Mojave to Big Sur. Couldn't stand it. Lost some great apps, 16 bit etc, and just a host of other dislikes. Reinstalled from my back up (Mojave) and kept getting the dialog box, Incompatible Disk, this disk uses features that are not supported on this version of Mac OS.
One hint to correct this was to reformat drive to extended journal. Did all again with the reformat, etc. Now when I start/restart I must first enter a drive password, wait then enter the computer password. Where did this come from and how do I get rid of it?
thanks

Hello,

Sounds like there is a firmware password, or FileVault was enabled.

You can check if FileVault is enabled in  > System Preferences... > Security & Privacy > FileVault. If it is a firmware password: Set a firmware password on your Mac.

Let us know if that works.

You are correct. Somehow I enabled the FileVault. Turned it to off and all is good. Thank you so much for your help.
