Sixty views and yet no body replied or helped. However, I just solved the issue and was able to get GTX 660 fully working in Mojave. First I used this script
bash <(curl -s https://raw.githubusercontent.com/Benjamin-Dobell/nvidia-update/master/nvidia-update.sh)
The screenshot you see in my above post is after installation of web drivers with the help of this script, but my card was still not working properly (metal was not supported).
Yesterday I remembered that I had a backup of kexts used in High Sierra. I just copied those kexts of nvidia web driver in the Library/Extension folder, before restarting the system deleted all nvidia web driver kexts from S/L/E and rebuilt the cache. The result was this. Every this is working fine
Hi There, Anyone experienced a graphic glitch issue when opening any video? this problem appeared after updated to high sierra 10.13, however there was no problem before in sierra 10.12.6, and my graphic card supposed to be native and no need for Nvidia web driver, So, any solution for this or...
GTX 660 was giving black screen before I installed web drivers 3220.127.116.11.40.127 with the help of github script, after that only resolution become full hd (i.e. 1920x1080) but card was not working properly. No hardware acceleration was available. I used nvidia web driver kexts from this WebDriver-318.104.22.168.40.105 version which were used in High Sierra 10.13.6. No boot flag was used. I just removed all web driver kexts erlier installed and copied these kexts in L/E and built cache and restarted the system. I have attached those kexts here I think all nvidia cards which were working fine in High Sierra can work in Mojave too by using these older kexts
