Question: Target disk is not booting
Hi everyone. I have a Mac mini 2018 running macOS Mojave 10.14.6. I have disabled Filevault on the internal SSD and disabled the T2-chip EFI encryption. I am able to get the Mac mini into target disk mode. The problem comes when I want to boot from the target disk using a different computer. I am able to access files on the Mac mini SSD (Macintosh HD shows up as an external disk) after connecting a thunderbolt cable to another Mac (running Catalina) and entering my password. From the GUI, my password works. But when I try booting into the Mac mini SSD from this other machine, it asks me for my password before the boot sequence even begins and my password just doesn't work.
I have even booted into Mojave on the Mac mini, changed my password, and reattempted the TDM boot to the second machine…but the new password wouldn't work either. After a few attempts, it asks me if I want to use my Apple ID to reset my password. When I did that, the computer restarted and attempted to boot into a recovery OS and you guessed it…that didn't work either (flashing 🚫 sign on the EFI boot).
How can I boot from this Mac mini in TDM using a separate computer? The password "protection" is just preventing me from doing anything.
