However I guess your issues depend mainly from not correctly installing the patched kext and generating the kextcache, instead of KextUtility, better using these commands from Mojave Terminal:Ĭhown -R 0:0 /S*/L*/E* & chmod -R 755 /S*/L*/E* While I can assure if you install correctly mine patched IntelHD3000 VRAM (through KextUtility in your case), they will work and will not affect in any way the brightness/sleep, you just need the stock backup AMD6xxx kext for enabling that, I meant you need the patched AMD6xxx kext based on AMDRadeonX3000 Framebuffer. Oh that's why, you have a MBP 15" dual GPUs IntelHD3000 and AMD/ATI 6xxx series, you need to use the original AMD/ATI kexts in order to have the brightness/sleep functions. I have both brightness control and sleep working in Mojave on my 15" mbp with a broken gpu that won't even boot unless disabled, this is how I did it : You have to do #1 again each time the nvram is reset. Sudo defaults write LoginHook /Library/LoginHook/LX3000.shĦ check that x3000 is loaded and gpu is set to integratedĬompare to the screenshot to make sure its correct.ħ optional, increase vram for hd3000 using Jacklukes method here Sudo chmod a+x /Library/LoginHook/LX3000.sh Mv /System/library/Extensions/AMDRadeonX3000.kext AMD/ (If you want to try this method, just apply the post install patches again and start from #3.)ġ boot into single user mode and set nvram variable: Click to expand.I have both brightness control and sleep working in Mojave on my 15" mbp with a broken gpu that won't even boot unless disabled, this is how I did it :
