Love the new Clover 3751!I found that clicking the option under clover works also
Just click it under Graphics
Thanks for the suggestion, I had gone through the normal fixes. I do use the iMac 17,1 definition, but the config edit fix didn't work. I actually tried a few of the fixes on that linked post just to rule them out.
Like I said originally, the web drivers worked with my 10.11.6 install, thought it took so modification. Same modifications dont work with 10.12, and neither do any other normal fixes.
Seems like someone else should be having a similar issue.
