This being said, I'm not sure Radeon HD5870 remained fully supported in High Sierra. It's supposed to be but I see a lot of people reported issues with it and had to roll back Sierra's AMD graphics kexts to get the card working. You may want to replace that old card by something more recent and fully supported. NB: Why use nv_disable=1 boot arg? You don't even have an nVidia graphics card! Thanks for your reply, I was used another Motherboard withthe HD 5870 and worked flawless I will try to took out the nv_disable 1 Link to comment Share on other sites More sharing options...
