Mirone Posted December 10, 2020 Share Posted December 10, 2020 I noticed that you are not using: https://github.com/acidanthera/whatevergreen/releases You could add it to your Kexts folder. Edit: But I agree with @Hervé. 1 Quote Link to comment Share on other sites More sharing options...

Del Posted December 11, 2020 Share Posted December 11, 2020 (edited) You are not the only person to face this issue on HD3000. Most people have HD3000 working ootb. But few unlucky ones have the same issue since Mavericks I tried with OC, Clover & Chameleon. No LVDS display without connecting hdmi. Tried injecting edid as well. No one has solved this issue afaik. PS: ioreg shows entry for Applebacklightdisplay & qeci is working on hdmi Hardware: hd3000 on series 6 chipset (dont need imei patch) Resolution:1366x768 (set in oc/clover/chameleon) yet it chooses 1280x1024 Edited December 11, 2020 by Del 1 Quote Link to comment Share on other sites More sharing options...
doddos920 Posted December 11, 2020 Author Share Posted December 11, 2020 my laptop IHD3000 on series 7, when I use Clover Bootloader is easy to get QECI, just set fake imei to 0X1C3A8086. But to get QECI with OC is really hard. Quote Link to comment Share on other sites More sharing options...
