I installed an RX 580 into my Mac, and honestly, no Apple logo screen or progress bars get annoying. Not knowing if any errors are present is even more annoying. So, I looked into EnableGOP and watched Mac Sound Solutions' video on how to do it. I ran a backup of my current ROM through the Macschraubers Rom Dump app and found this.

"Length of 2nd VSS Store is wrong (FF FF FF FF)
20454 bytes free space of 65464
VSS1 (Formatted) (Healthy), found 77 variables (30 valid, 47 deleted)
VSS2 (Formatted) (VSS2 header problem), found 42 variables (42 valid)"

I did try a sudo nvram -c to try and help, nothing changed. Every time I try to do the NVRAM reset on my keyboard, my USB power goes out before it can register the 3rd reset, so I only get to the second chime.

I am in no way familiar with how to handle ROMs or programming, I just want to be able to see my boot up screen and errors with the RX 580. Can someone help me fix or clean my ROM so I can carry out with EnableGOP?
