Hi Team,
After preparing a USB drive with Monterey and configuring its EFI partition for a 2011 macmini5,3, I used bootpicker to choose the EFI volume, and then chose Install Monterey to continue installing macOS on a macmini5,3's internal drive. From the macmini5,3, the Monterey installer seems to boot most of the way and then reaches a flashing screen (1:30 into this video):
Verbose logging shows no significant errors. Has anyone encountered this and found a way to get past it? The project team has an
issue report on this.
