Administrators Hervé Posted January 29, 2023 Administrators Share Posted January 29, 2023 IOReg and OC config show you're using KBL mobile framebuffer 0x591e0000 rather than desktop framebuffer 0x59120000 as expected and recommended by the WhateverGreen User Manuel. ID: 59120000, STOLEN: 38 MB, FBMEM: 0 bytes, VRAM: 1536 MB, Flags: 0x0000110B TOTAL STOLEN: 39 MB, TOTAL CURSOR: 1 MB (1572864 bytes), MAX STOLEN: 115 MB, MAX OVERALL: 116 MB (122171392 bytes) Model name: Intel HD Graphics KBL CRB Camellia: CamelliaDisabled (0), Freq: 1388 Hz, FreqMax: 1388 Hz Mobile: 0, PipeCount: 3, PortCount: 3, FBMemoryCount: 3 [1] busId: 0x05, pipe: 9, type: 0x00000400, flags: 0x00000187 - ConnectorDP [2] busId: 0x04, pipe: 10, type: 0x00000400, flags: 0x00000187 - ConnectorDP [3] busId: 0x06, pipe: 10, type: 0x00000400, flags: 0x00000187 - ConnectorDP 01050900 00040000 87010000 02040A00 00040000 87010000 03060A00 00040000 87010000 Note that this framebuffer defines 3 x DP outputs so you may have to patch the connectors depending on your own physical output ports. No support for VGA of course. Your OC config currently changes connectors con1 and con2 to HDMI type, leaving con0 unmodified. You should also change SMBIOS from iMac18,2 to iMac18,1 since former uses AMD dGPU whilst latter uses KBL iGPU only. NB: you're injecting iGPU unifiedmem property with value 0x80000000, i.e. 2GB; as such your graphics info should show 2048MB in About this Mac, not "[...] 1532MB or whatever the MB [...]".

ashura1125 Posted January 29, 2023 Author Share Posted January 29, 2023 could you show me or give a me a guide on how to change the frame buffer Link to comment Share on other sites More sharing options...
Administrators Hervé Posted January 29, 2023 Administrators Share Posted January 29, 2023 Just modify your OC config using any plist editor app (eg: Xcode, ProperTree, PlistEditPro, etc.) or basic text editor (eg: TextEdit) or dedicated app such as OpenCoreConfigurator (OCC). How else did you build your setup? Or did you just copy/paste a complete OpenCore EFI folder from somewhere and somehow got lucky? Link to comment Share on other sites More sharing options...
ashura1125 Posted January 29, 2023 Author Share Posted January 29, 2023 I had a friend who used a Optiplex SFF model of the 7050s so heh i guess i just got lucky and her efi worked she has the same computer but in the SFF but the difference between the sff and the "regular" models is the regular uses intel hd 630 desktop graphics but the SFF model my friend has uses the laptop graphics even though there the same desktop cpu and as you mentioned the framebuffer is different and my friend found the efi on github and it has been a ton of help and i would even go as far as to say that github has helped me alot and watching youtube videos and figuring out everything .
