Hi everyone,

I have been using OpenCore Legacy Patcher for a while - successfully. Running Monterey on my Late 2012 27" iMAC.

I have just tried to use the new Opencore legacy patcher version (0.6.8) to install the new version of Monterey onto the external SSD I was using for the previous version.

I follow all of the instructions and have created and built the installer onto the external SSD.
However, when I click on the EFI boot icon and then select the installer icon on the next page, the iMAC goes into the Apple Recovery Mode and says the SSD is "locked".

Am I doing something wrong, or is there a setting I need to change so I can boot from the SSD I installed OpenCore on?

My Mac is a 27" late 2012.

I don't think I had these issues when I first got Monterey working via OpenCore.
