Hey you might want to try some of the new progress I've made, especially if you only have 1 GPU. Basically go into Clover and set the sys def you prefer, whether that's MacPro6 or 5 etc. Click ok. Then on the board ID just change it by 1 digit at the end. Copy the board id. Then go into S/L/CoreServices and change the PlatformSupport.plist and add this fake board-id to the list. That way it'll still boot.
Now you should have a fully functioning GPU fully utilizing the nvidia web driver features including MST or 5K. Doing it this way, I no longer have any cursor issues, and you can potentially keep other enhancements based on sys def that you may have set up. You shouldn't have to change AGDP plist either, so this change will survive updates.
Note however, that I'm not sure what else might BREAK elsewhere because it's a fake board-id. For instance, I don't bother with iMessage. But everything else for me has continued to work and work better than before. Airdrop, wifi, bluetooth, USB, sound, all the normal things that sometimes are hard to make work... everything. Not sure about CPU states and power management, that's another thing I don't care much about.
Your mileage may vary.
For me, with a 2nd GPU, this hack doesn't let the 2nd GPU's ports be active. It's still in the machine and accessible to apps if an app wants to use it, but didn't solve my problem of being able to run a 5K AND a MST display off the one card (I wanted to plug the 4K MST display into my second GPU but can't get any luck out of the ports). Only way I can make the ports work is if I use a valid board-id, but then I lose MST/5K support which I don't want to give up.
Anyway, hope this helps someone who wants to try this out especially if you have a MST or 5K display (of any kind).
