Hi,
today i was trying to update my machine to High sierra from Sierra. When i started the installation, i got the error "this mac is not compatible with high sierra". So i thought that i just needed to update the system definition in Multibeast... Huge mistake! I change from mac 5.1 to imac 17.1 and when i rebooted the screen went black when i arrive to the login. It was really stupid of me to update without searching on the forum first!
Now i need some help to recover the screen or switch back to mac 5.1. Can i do this from clover ? is there a clover flag to help with this ?
I found this thread about the black screen:
But it doesnt really help in my case. I know my machine works fine i just need to switch back to the previous profile.

Black Screen with MacPro 6,1 or iMac 15 or iMac 17 System Definition
The MacPro6,1 and iMac15/17 perform special functions on their specific OEM GPUs/Displays. The MacPro6,1 unloads 1 GPU (with no ports) and leaves one functional for it's pseudo CrossFire function. The iMac15/17s apply a special EDID for their 5K displays. The following snippet is taken from...
