Just thought I'd report back ... So the same thing started happening again, but this time would not even get into MacOS with QE/CI whatsoever. But would boot with no patch. I spent another half day trying to figure it out with various combinations of patches, fixes etc.. before turning to hardware as a possible cause. Turns out it was only a bad HDMI Cable ? nothing else - Ouch! Don't know how or why that would only affect enabled graphics, but it did. Strange

Well that worked - kinda I used your patch, rebooted - great ! no green screen and HDMI audio once again. However a couple of boots later the green screen appeared again - strange. I noticed I had an Apple folder in EFI - deleted it - reboot, no green screen - Nice! However I could no longer open Hackintool - it crashed every time. Put back my original ID 59160009 and everything is now back to normal. Strange how that happened but the machine is 100% again. Thank you for your help once again.

Fixed the Green Screen issue by changing Connector in Hackintool to HDMI - but now I've lost HDMI Audio

Kabylake-R Here's a realtime video of what's happening on Boot.

So Since after installing the latest Mojave Security update, I'm getting a Green Screen between Verbose and Apple Loader lasting appx 60 seconds. Everything works after that, but its annoying as hell. Have tried a couple of Platform ID's and SMBios without any luck. Same result in both OpenCore (6.0) and Clover (5120). Latest WEG / Lilu System has not had any issues the past 9 months using 0x51960009 / 59168086 or 0x3EA50004 / E39B8086 Same Result regardless if Properties are added via Clover Devices or via SSDT Using Single 1920x1080 monitor Config Attached I hope Apple didn't screw with the driver on this update. config.plist.zip

Ok so it turns out that in order to get Graphics working 100% in Mojave with audio all that was required are these two lines in Xcode. This enables 4k, VDA decoder and appears to have 3 video outputs (Probably 2x via USB C which I cannot confirm). I feel pretty certain at this point that the problem with Catalina stalling lies with faking of the ID. Maybe there will be a future solution. <key>PciRoot(0x0)/Pci(0x2,0x0)</key> <dict> <key>AAPL,ig-platform-id</key> <data>CQAWWQ==</data> <key>device-id</key> <data>FlkAAA==</data> </dict> </dict>

Ok last attempt maybe ... I slow motion captured the output of verbose and transcribed the errors / warnings that I could see below (there might be a some typos) Could any of these be the potential problem in Catalina ? “name” not a kext “failedImage” not a kext ACPI Error: [CPUB] namepace lookup failure, AE not found (20160930/dswload-292) ACPI Exception: AE_NOT_FOUND.

I have no idea either If it works with Mojave it "should" work with Catalina. I think I will have to stick with Mojave for now, look into OpenCore perhaps or even non-vanilla way of doing things

This config works perfect in Mojave 100% Removed some unnecessary bits, tested with other ID's but this is the config that work correctly with Acceleration and Audio in Mojave. Catalina is a mystery, same freeze, same spot each and every time.

Ok ... progress (I think) This config is 100% working in Mojave with no clover injects or ig-device-id. Coffeelake might be the answer, I guess the Kabylake-R is closer to 9th gen than 8th :-S .. Graphics now shows as an Iris Plus 655 though (manual rename) However the config STILL hangs at the same point in Catalina

I wish it did, I transferred my SSD to another (same model) machine in case there was a problem with board. Unfortunately the same problem, Catalina hangs on boot whenever there is a new patch. Everything works 100% in Mojave on both machines with your original graphics fix @ https://Olarila.com/forum/viewtopic.php?f=28&t=10814 and the following settings in clover: Inject intel = yes ig-platform-id = 0x59160009 (clover) iMac 18,1 Catalina will also boot successfully with this patch, but only if inject intel = no, so obviously no acceleration, with inject intel turned on it hangs at the same point which makes me think it might be a Catalina kext issue perhaps ? If I try a new Hackintool patch without the clover properties, I can get acceleration in Mojave, but its a pinkish screen and SMBios makes no difference (tried every 7-8th gen Mac in the list). Frustrating

Comparison between the working Mojave version. Platform ID in your original Mojave patch is Coffeelake though. In Mojave I also need to inject intel and set ig-platform-id to 0x59160009 however

Tried with connectors patch ... no luck it still hangs at exactly the same point. Plist attached. config.plist.zip

Nope 1080

So near yet so far ... I'm certain (kinda) this must have something to do with it ?

I've gone back to scratch - looked over the initial pacth (which was your one here) which works perfectly on Mojave. Attempted to Re-patch using Coffeelake with Hackintool but still no luck whatsoever Something in Catalina just does not want to play nice. Anything else you can think of ?

I wish I had better news .... but It's hanging at exactly the same point.

attached config.plist.zip

Maybe I'm doing something extremely stupid ? (would not be the first time) Appreciate anything you can do. I've included a bootable version and the one that hangs.

Tried that too .... Boot appears to get stuck at exactly the same point every single time if there is any patch or injection in place Could the fact that there is no "Intel Generation" showing in Hackintool be related ? Pic attached of the stall for reference. https://pasteboard.co/IJrNZ1o.jpg

Native is : 0x59178086

Ok I went back to a fresh start, with fresh config file. Patched it using your settings Xcode and end up with exactly the same problem (screenshot of the settings which I hope you can confirm are correct?). https://pasteboard.co/IJmSnqk.jpg 0x59160009 is the platform ID that works perfectly in Mojave with acceleration. SMbios: iMac 18,1 .. I started there. Tried Hackintool to generate a patch ... clicking the "eye" shows me coffee lake, so tried the defaults - No Luck. Tried the 620 kabylake 0x59160009 and 0x59160000 settlings - no luck Tried pretty much all the patch options in Hackintool on / off - no luck. Tried multiple other SMBios e.g. MacBook Air, Mac Mac Mini's which also have UHD graphics - no luck Every time I end up with a freeze during boot at the same point: "render compression for IO surface is enabled" If intel is injected, Without injecting I can boot with 7mb and no acceleration. https://pasteboard.co/IJmTc2w.png I have tried your EFI folder from the thread with the patches included (I had to remove some unessesary kexts and add -lilubetaall) ... I get the same outcome as above. Any other ideas ?

I assume I did it right by replacing the item in the plist? It did not do anything though, simply hangs on boot at the same point. Mojave works perfectly with the old settings with with HDMI Audio.

So I upgraded one of my machines to Catalina and have it working (mostly) with the exception of the Graphics / HDMI Audio. Currently showing Intel UHD Graphics 620 7 MB I used the same SMBios and Graphics settings as I did for my working Mojave install, have tried a number of various SMbios's but no luck. Boot hangs at "render compression for IO surface is enabled" if I attempt to inject intel. Any Ideas ? Send Me File attached. Muchos Thanks Send me Steves-iMac.zip

Thanks for the kick in the right direction it looks like I am not the only one having an issue where there is no MAC address. Now I just hope the airport cards I ordered work and I'll be 99% working.
