Hi, as far as I can tell, SSDT-BRG0 may solve issues since it defines missing pci-bridge. Send me an IOReg dump on Telegram (my contact here) as it contains SMBIOS serial numbers, as I hope you don't wanna spread publicly your data

@dreamwhite Good morning. Are you talking about 6600 and Ventura with iMacPro or MacPro SMBIOS? Black screen if Henbury patch not added? I’lI get the IOReg with the patch applied, right? Thanks.

Good morning, yeah, theoretically SMBIOS doesn't matter, so you just need to fix pci-bridges. Once you get the IOReg send it on my Telegram so I can send you the right SSDT-BRG0, properly configured for your PCI path

Ok, wait I,m out.

@dreamwhite Ok, I've tried SSDT-BRG0 with iMac19,1 and MacPro7,1 SMBIOS.

iMac19,1 runs fine, I don't see any differences except the different path in IOReg. PCI0@0/PEG0@1/PEGP@0/BRG0@0/GFX0@0

But MacPro7,1 can boot now Ventura without the Henbury patch. As I say in the README, iMac doesn't need Henbury patch in Ventura but MacPro and iMacPro both do, to not have black screen when reaching the Desktop. With SSDT-BRG0 the patch is not needed.

Henbury patch drops down GeekBench 5 Metal scores. With SSDT-BRG0 scores are the same as on iMac without Henbury patch. So, your SSDT-BRG0 seems to be a better solution to avoid black screen on Ventura when using SMBIOS that lack iGPU.

Thanks!

Yes, I'll add a comment in the README file. Thanks again.
