jones333333 Posted April 15 Share Posted April 15 So I am running an HP 400 G6 mini pc with Sonoma, all is working very fine and the only issue that I am still encountering with this system is the HDMI that doesn't work. This system have 2 video output-> DisplayPort et HDMI. The display port is working but I would like to fix the HDMI output. I tried to understand the procedure of Dortania Guide in order to patch the HD 630 but I failed. Could someone help me with this? I put my config file and IOReg extract Thanks in advance for your help!! Archive.zip Link to comment Share on other sites More sharing options...
Administrators Hervé Posted April 15 Administrators Share Posted April 15 Seems your HP 400 G6 is fitted with a Comet Lake CPU given that the reported iGPU id is 0x9BC8. It's a desktop platform, yet you use mobile framebuffer 0x3E9B0000 which natively defines the following 3 ports: [0] busId: 0x00, pipe: 8, type: 0x00000002, flags: 0x00000098 - ConnectorLVDS [1] busId: 0x05, pipe: 9, type: 0x00000400, flags: 0x00000187 - ConnectorDP [2] busId: 0x04, pipe: 10, type: 0x00000400, flags: 0x00000187 - ConnectorDP 00000800 02000000 98000000 01050900 00040000 87010000 02040A00 00040000 87010000 This is not suitable given that 1st output port (i.e. connector con0) is defines as an LVDS port. DP output appears to attach to 2nd connector con1 in your IOReg. I would suggest you opt for the desktop framebuffer recommended in the WEG user Manuel, i.e. 0x3E9B0007 which defines the following 3 ports: [1] busId: 0x05, pipe: 9, type: 0x00000400, flags: 0x000003C7 - ConnectorDP [2] busId: 0x04, pipe: 10, type: 0x00000400, flags: 0x000003C7 - ConnectorDP [3] busId: 0x06, pipe: 8, type: 0x00000400, flags: 0x000003C7 - ConnectorDP 01050900 00040000 C7030000 02040A00 00040000 C7030000 03060800 00040000 C7030000 This should give you a better chance to obtain DP + HDMI output. If you do, identify which connector is DP and which connector is HDMI so that you may patch the HDMI one accordingly (i.e. set its type to 00080000) should you wish to enjoy HDMI audio. You may also want to switch SMBIOS from iMac20,1 to MacMini8,1. Link to comment Share on other sites More sharing options...
jones333333 Posted April 16 Author Share Posted April 16 Thanks for your help Hervé! I will try these settings this evening. Also thanks for your advise for the SMBIOS! Link to comment Share on other sites More sharing options...
jones333333 Posted April 16 Author Share Posted April 16 Hervé, I changed my SMBIOS to MacMini 8,1. What I just discovered now is that my cpu is recognized as i5 10400t but it is in fact a 10500t. Anyways to fix this? Link to comment Share on other sites More sharing options...
Administrators Hervé Posted April 16 Administrators Share Posted April 16 That's entirely cosmetic and bears no influence on your Hackintosh. Furthermore, it probably only appears in an add-on application such as About this Hack. If you want the proper CPU model to be reported, inject its CPUID in your OC config.

jones333333 Posted April 17 Author Share Posted April 17 Hervé, I did the changes regarding my Framebuffer and I tried to patch the connector to HDMI 00080000 (tried for con0 and con2 as I didn't know which one is the HDMI ) but still I am unable to use the HDMI out? I suspect that something must be wrong with my config file. May I ask you to have a look please? Thanks in advance! config.plist.zip Link to comment Share on other sites More sharing options...
Administrators Hervé Posted April 17 Administrators Share Posted April 17 It's just a matter of framebuffer and matching of connectors with physical outputs. On rare occasions, certain outputs may not work at all. Patching the HDMI port to type 00080000 is only required to gain HDMI output, it's not required for video output. All I can suggest is that you experiment with the various CFL/CML framebuffers and check them all out for HDMI output. Link to comment Share on other sites More sharing options...
jones333333 Posted April 24 Author Share Posted April 24 I am still trying to define with SMbios should be the best with this system, iMac20,1 or Macmini 8,1. It's seems that iMac20,1 is cometlake cpu and Macmini 8,1 cofee lake cpu. As my HP has a comet lake cpu should it be not best to use the iMac20,1 smbios? What advantage should i got when using Macmini 8,1 with my system? Link to comment Share on other sites More sharing options...

jones333333 Posted Thursday at 08:55 AM Author Share Posted Thursday at 08:55 AM Hervé, iItried the SMbios imac20,1 and it seems that I am getting better geekbengh score with this SMBIOS. Also, it seems that the VGA output of the HP is also working now. So I have DP out and VGA out working but no HDMI out. The frame buffer that I selected is 0x3E9B0007 and when I look in Hacintools it seems that I got 3x HDMI out instead of DP When trying to boot with only HDMI out, I can boot and see the Apple logo but then the display is going to sleep as it seems that I loose the signal when reaching the Apple login page Link to comment Share on other sites More sharing options...
