I’m back sorry but I’m doing like 20,000 things at once, also Mojave 10.14.2 update came out today
Maybe I shouldn’t have spoken to soon , I feel very bad
I hate having to give good people bad news
I find out what the problem is
The method works but only on EUFI boards
I did the exact same thing with both systems, clean install Mojave and at boot I was having the black screen
So when I finally bypassed the black screen I was very happy and I wanted to share with the ones that were having the same problem
but since I’m used to Nvidia glitch and broken graphics
I didn’t notice that the bios board doesn’t have acceleration until later today
It was my mistake because as soon as the old system loaded
I turn it off and started working on my system right away
since the card was working perfectly fine on my system, I thought that I will do the same on the other system
since I did both the same way
The card work flawlessly in Mojave the way I described but it requires a EUFI board
It seems like the old bios board is missing some features but I will say that is missing the most obvious “EUFI support”
Here are some pictures for you to see the differences between both systems
I did exactly the same thing in both systems but the EUFI board is the only one that has acceleration and properly recognized the card
Also the big difference is that the EUFI board has metal support enable while the bios board doesn’t
Yes you can boot the system but the card can’t work the way it should because the old board is not EUFI and metal is not enable
I guess Mojave needs an EUFI board
If anyone can confirm , if you have a bios board running Mojave with metal support please post the picture
Maybe a newer bios board will be able to run Mojave but I will say that the 775 might not be compatible
Running an EUFI board in legacy mode is not the same as a bios only board
Also there are some drivers in clover that are only for EUFI mode , maybe one of those drivers is need it for the legacy bios
But EUFI drivers does not work in BIOS boards and those features are only for EUFI boards, that’s why the equivalent does not exist in bios driver
Well my apologies
The card works using that method but it requires an EUFI board because it doesn’t fully work on bios board
Because there it seems to be a limitation in the bios firmware
Once again my apologies
If I find out anything I will come back and tell you
Hope you understand , once again sorry for the confusion but is clear now
