Lucy183 Posted June 10, 2017 Author Share Posted June 10, 2017 Hi LuCyr04. I got native resolution on my HD 5670. Still no acceleration by the gpu, but it gets a bit better for use, for now. I just switched the HS kexts from the Sierra 10.12.5 AMD5000Controller.kext, AMDRadeonX3000.kext, AMDRadeonX3000GLDriver.bundle, AMDLegacyFramebuffer.kext and AMDLegacySupport.kext.I do this to be able to reach desktop but I want it fully functional.. @ricoc90 can you look in my dsdt? i think it's something wrong with it..

cedroxim Posted June 10, 2017 Share Posted June 10, 2017 You should have a problem in the dsdt, clover or kext if you have modified it. I have the same asus hd5870 and excellent functional with high sierra.

Guest ricoc90 Posted June 11, 2017 Share Posted June 11, 2017 I don't think it's your DSDT, but your motherboard. Someone reported that for non-apple AMD cards, you'll need a helper GPU. Your motherboard does not have one... That might be the reason why cedroxim's card IS working, because his mobo does have integrated graphics -- Could you run this app for me? While in it. search for "display" and tell me the location of your graphics card IORegistryExplorer 3.zip Link to comment https://www.insanelymac.com/forum/topic/324279-radeon-hd-5870/page/3/#findComment-2441835 Share on other sites More sharing options...

Wppley2 Posted June 19, 2017 Share Posted June 19, 2017 Well, it's not ideal, but I got video acceleration by switching several kexts to those of the Sierra, but with 24-bit colors (if anyone can explain why?). It's great to meet HS. Link to comment https://www.insanelymac.com/forum/topic/324279-radeon-hd-5870/page/3/#findComment-2447151 Share on other sites More sharing options...
