vbmota Posted February 2, 2022 Share Posted February 2, 2022 (edited) I have a setup with Mojave 10.14.5 and Catalina 15.7 and edited DSDT for all working devices. My only trouble is a washed screen since the apple logo until all desktop loads and all. With Hackintool it shows me Video Fully Supported (Catalina runs Metal screen saver and all) Edited Edid wont help for it, but avoided blank screen. If someone have working machine like this, please can you help? I will post my EFI. Samsung NP530U3C-AXXXX Proc : Intel Core i7 Ivy Bridge Motherboard : SAMSUNG ELECTRONICS CO., LTD.

vbmota Posted February 3, 2022 Author Share Posted February 3, 2022 (edited) Sorry, but removing all that I got a blank screen, but my HDMI is always ok. I sent a not updated config.plist. Now its attached here with all EFI folder. If you could explain why and how to apply: |that apply to Broadwell & later iGPUs and add: AAPL,ig-platform-id 03006601 DATA framebuffer-fbmem 00008000 NUMBER // Reduce FBMEM from 16MB to 8MB Cheers!

vbmota Posted February 3, 2022 Author Share Posted February 3, 2022 Well, I will post my booth config.plist for you to see what I got now, before testing it. One with Device Properties edited and no Graphics changes. Other with Graphics without inject Intel, platform-id and EDID. Can you check that, please? config.plist config - without Graphics parameters.plist Link to comment Share on other sites More sharing options...

My Dell Latitude E6430 with the same graphics Intel HD4000 works as it should. I looked at your config and see nothing what to look. Yes, ig-platform-id is good. What else to look? I am not agree with your Quirks section but I don't think it influences on graphics. For example SyncRuntimePermissions should be true for my mind while you set false.

vbmota Posted February 3, 2022 Author Share Posted February 3, 2022 11 minutes ago, Hervé said: @vbmota minhas desculpas, acabei de perceber que cometi um erro na minha resposta acima (agora corrigida). O tipo de valor para framebuffer-fbmem é DATA , não NUMBER . Remova também a falsificação do seu ID de iGPU, não deve ser necessário e você o manteve no lugar. Thanks. Like that? config-herve.plist Link to comment Share on other sites More sharing options...
vbmota Posted February 3, 2022 Author Share Posted February 3, 2022 (edited) If I remove FakeId in |Devices|, I lose bluetooth... With only change framebuffer-fbmem to DATA I got a blank screen. So, I have a great challenge here. Theres not to do more. I will post my DSDT edited with care by @MaLd0n. Someone? Cheers DSDT.aml Edited February 3, 2022 by vbmota Link to comment Share on other sites More sharing options...
