Ragu Posted February 22, 2018 Share Posted February 22, 2018 I tried booting with your files... Brightness and Audio successfully working...But new problem is display is continuously FLICKERING from apple logo starting to 50% loading time... After 50% display working normally...I have tried disabling "Enable Trim for SSD" in kext and kernal patches..This will cause No Display Out in 0% to 50% apple logo loading... After 50% display working normally... Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted February 22, 2018 Moderators Share Posted February 22, 2018 You mean the boot graphics glitch before getting to the login screen? Check BIOS, see if you could try Enabling Legacy Option ROMs Link to comment Share on other sites More sharing options...
Ragu Posted February 22, 2018 Share Posted February 22, 2018 I have already enabled that option... Graphics glitch also comes.. But i don't mind... But, My problem is.. Display Flickering approximately 2 to 3 times per second continuously while apple logo is loading...(display backlight is continuously switching brightness like on/off DJ light effect..) Upto half the way of apple loading bar.. After that it was normal and showing graphics glitch like you told... After that everything working.. Before your patches the webcam was worked... Now its gone... No camera detected erre in face time... Link to comment Share on other sites More sharing options...
Administrators Hervé Posted February 22, 2018 Administrators Share Posted February 22, 2018 You need to replace the IOGraphicsFamily patch in Clover config and enable it. In High Sierra, the patch is: Find: 0100007522 Replace by: 010000EB22 ` Now that you have Optimus enabled again in BIOS, can you post a new IOReg output? 'seems the dGPU would be RP05.PEGP@1C,4...

Ragu Posted February 22, 2018 Share Posted February 22, 2018 Here is my ioreg with optimus enabled in BIOS... Now only i'm going to try IOGraphicsFamily patch.. ioreg with optimus enabled.zip Link to comment Share on other sites More sharing options...
Ragu Posted February 22, 2018 Share Posted February 22, 2018 I have changed IOGraphicsFamily like you told.. Now I have apple logo without loading bar for 4 to 5 sec.. after that loading bar comes but immediately got black screen (no backlight at all) for upto 50% of loading bar... after that only display switched ON ... But i think the IOGraphics patch is for Graphics glitch... now the duration of glitch before login is decreased... Link to comment Share on other sites More sharing options...
