Inadvertently? One needs to unlock System Preferences > Security & Privacy > File Vault and press the Turn On File Vault button. Did you save the recovery key? Otherwise, did you "inadvertently" encrypt your boot drive using some other software?
All I know is it created some jibbers as a user name. I was made aware of that when I went to reboot after dealing with Mojave patcher. I did not see any firevault key. Should I turn fire vault back on? I have it off now
MP 5,1 supports Mojave, no “patcher” necessary, so I’m not quite sure what you’re trying to do. Is your firmware 144.0.0.0?
I could not get it to advance to 144.000 and I tried the button hold many times with metal card installed
It’s all just so time consuming and stressful. Thankfully most of the data is in the cloud. But I would love to get that drive to boot again

Surprisingly it installed Mojave with my original GPU and no boot rom update. But the graphics were terrible. I now know what I did wrong. I thought the metal GPU could not work with High Sierra. And I also thought the black screen was only with Mojave. I carbon cloned a backup of the drive I lost to encryption and got the rest back from ICloud. It will let me drag items from the corrupt one to my new one. Still would love to know how to decrypt via Terminal. I will tackle installing the metal card tomorrow. And I will follow that link to the letter. ThanksYou need to read this and follow to the letter

Ok, so I booted up on the drive that the the Mojave installer with the metal card installed. Began the install and it told me to shutdown, and upon reboot, hold the button til you hear the long chime. I did all that. Display works much better with this card of course, BUT, the Boot ROM version still shows MP51.0089.800. Is it because I installed the Mojave installer on a SSD drive that was formated to APFS?
This is difficult for a reason.
You need to upgrade to Mojave using the App Store Mojave installer application on High Sierra installed on internal SATA drive. You probably need to start over w/ HS and all its updates, a HS supported Metal capable GPU, then upgrade to Mojave following the instructions to update firmware. This way will work.
