Catalina This time ... UHD620 Graphics Woes

Recommended Posts

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

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.

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?).

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.

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 ?

Maybe I'm doing something extremely stupid ? (would not be the first time) :wallbash


Appreciate anything you can do.


I've included a bootable version and the one that hangs.

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 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 :wallbash

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 :frantics
