Moderators Jake Lo Posted May 4, 2021 Moderators Share Posted May 4, 2021 from the Clover file you attached, you have AAPL,ig-platform-id =05003B19 device-id = 1B190000 That's not what I'm seeing here Link to comment Share on other sites More sharing options...
nickelnoff Posted May 4, 2021 Author Share Posted May 4, 2021 OK - my mistake on the last screenshot. Too many config.plist files floating about. The OC Config LHS, Clover Config RHS Below: So can confirm: AAPL,ig-platform-id =05003B19 device-id = 1B190000 OK - I set back to MacBookPro13,1 since this is what I have been using with Clover and also set the boot flag - wegnoegpu since this has also been in use. Are all boot flags from Clover transferable to OC ? Here's what I know see when I try to boot: Error shown: Lilu patcher: @ failed to solve __ZN31AppleIntelFramebufferController17IsTypeConlySystemEv, err2 WhateverGreen igfx: @ failed to route IstypeCOnlySystem EDIT: As far as I can tell from here: https://www.insanelymac.com/forum/topic/325987-whatevergreen-support-topic/page/55/ The above might not be causing issue.

Moderators Jake Lo Posted May 5, 2021 Moderators Share Posted May 5, 2021 Looks like graphics is not loading. Might have to tweak the graphics properties some more. Your display is 4k so maybe change the DVMT script from setup_var 0x432 0x3 to setup_var 0x432 0x4 Link to comment Share on other sites More sharing options...
nickelnoff Posted May 6, 2021 Author Share Posted May 6, 2021 This is done from the BIOS ? If it was working with Clover with the current settings wouldn't the same be working with OC ? I can boot the machine and connect with VNC so it doesn't seem to crash on boot up now. But just no frame buffer available. Link to comment Share on other sites More sharing options...
nickelnoff Posted May 6, 2021 Author Share Posted May 6, 2021 Hi @Jake Lo does this setup_var change need to be done by the BIOS patch method as shown here: https://osxlatitude.com/forums/topic/9179-dell-latitude-e7x70-installation-guides-uefi-only-clover-and-opencore/ or is there an alternative approach with WEG ?

Moderators Jake Lo Posted May 6, 2021 Moderators Share Posted May 6, 2021 If you're using my 7510 bootpack from the guide, it's already included under /EFI/Boot/DVMT Modify grub.cfg and change setup_var 0x432 0x3 to setup_var 0x432 0x4 Save and reboot Go to the BIOS Create a new boot option, call it DVMT or whatever you like Point it to /EFI/Boot/DVMT/Bootx64.efi Save and reboot, press F12 Select the new boot option DVMT or whatever you assign it At the grub shell, select Option 1 for "#1 iGPU-only configuration. No dGPU. " Or you could download modGRUBShell.efi, add it to drivers folder and enable it in the Config file At bootup, press spacebar to review the boot option. Select it to boot to the Grub Shell and run the command setup_var 0x432 0x4 1 Link to comment Share on other sites More sharing options...

When Option 1 is selected the machine reboots. Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted May 6, 2021 Moderators Share Posted May 6, 2021 That's correct, it made the modification and reboots. Link to comment Share on other sites More sharing options...
nickelnoff Posted May 7, 2021 Author Share Posted May 7, 2021 HI @Jake Lo - finally moved forward and have laptop graphics is working. I am not sure the "setup_var 0x432 0x4" changed anything however I downloaded your boot pack (many thanks) and made some small adjustments and things kicked in. I've attached the config.plist that shows the changes made. They are essentially now looking like this: What doesn't yet work is any of the external ports. config.plist.zip Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted May 7, 2021 Moderators Share Posted May 7, 2021 In the BIOS, under graphics, there should be an option next to "enable switchable graphics", to not forward external graphics to the DGPU. I can't remember the exact wording, I don't have the laptop with me now. Found this Make sure it's disabled Link to comment Share on other sites More sharing options...
