VortexisTV 0 Posted August 22, 2020 Share Posted August 22, 2020 (edited) I'm trying to enable UHD 620 graphics on my laptop since it's almost impossible to use Catalina with it disabled (freezing), so after I followed this guide, every time I try to boot into Catalina it does get stuck at the apple logo and progress bar. Heres also the EFI if anyone wants to look at. I'm using this UHD 620 plist to try to get my graphics to work.

Hervé 2,099 Posted August 22, 2020 Share Posted August 22, 2020 This is most likely happening because you've not renamed your DSDT's Embedded Controller (or injected an "EC" device). Your patched DSDT currently shows 2 x devices with "PNP0C09" HID: H_EC and EC0. These would need to be renamed to "EC" as known and documented since last year. Lack of "EC" device causes boot freeze.

VortexisTV 0 Posted August 22, 2020 Author Share Posted August 22, 2020 I can't find where PNP0C09 is on my DSDT editor. Where did you find the devices at? Link to post Share on other sites
VortexisTV 0 Posted August 23, 2020 Author Share Posted August 23, 2020 I've done the fake EC method because I couldn't find PNP0C09 in my DSDT but it does still hang in the progress bar or login screen but I can't do anything. Link to post Share on other sites
Hervé 2,099 Posted August 23, 2020 Share Posted August 23, 2020 I don't know how you could possibly miss these 2 x instances of Embedded Controller in the DSDT located in the CLOVER/Patched folder of the zipped EFI you posted... Looking further into your setup, I'm not certain the graphics properties you inject are correct for UHD 620. I would also question some of these unusual kext you inject. Start with the basics (VirtualSMC & PlugIns, Lilu, WEG, AppleALC, PS2 controller) and add further kexts one by one as you go along. You also appear to use an NVME SSD; be aware that not all such SSDs are supported, some Samsung are notorious for causing issues and must be avoided/replaced due to incompatibility. You can search the Net/forums about this, there are lists of compatible/incompatible NVME SSDs. Link to post Share on other sites
VortexisTV 0 Posted August 24, 2020 Author Share Posted August 24, 2020 (edited) Trying to search PNP0C09, H_EC and EC0 got me no results on my MaciASL. I don't know how you found it but mine cant find it. EDIT: I see that I needed to decompile it first, I apologize for my noviceness lol Edited August 24, 2020 by VortexisTV Link to post Share on other sites
