AkimoA Posted December 2, 2018 Share Posted December 2, 2018 CPU: Intel Q9550 @ 2.83GHz, MOBO: Gigabyte P43-ES3G WEG will not work properly on non UEFI Boards ...see manual... therefore this is no solution. Quote What is the state of 10.13 support? At the time of the release 10.13 is still being tested, so no support could even be thought about. There exist cases of broken AMD graphics on pre-Nehalem CPU chipsets. If you have older hardware please stay away from using 10.13. For other systems WhateverGreen may work if no drastic changes happen in 10.13. Link to comment Share on other sites More sharing options...

But start the system in Safe Boot mode,it can work. And I didn't use whatevergreen, so I think it can be work. I use whatevergreen only to tried,but it didn't work.

AkimoA Posted December 2, 2018 Share Posted December 2, 2018 9 out of 10 cards work in vesa mode , there are known issues on these 7xxx cards on HighSierra and old 775 socket cpus , go back to Sierra or change card /or mobo & cpu , sounds harsh but is the truth Link to comment Share on other sites More sharing options...

AkimoA Posted December 5, 2018 Share Posted December 5, 2018 hehe nice , well ok i mentioned go back to Sierra as well tbh good catch , in didnt expect Sierra kexts still to respond very well in Mojave( in terms of dependencies) in this case OP should take it for a spin Link to comment Share on other sites More sharing options...
