Amazing, thank you Maldon. Would you happen to suspect whether internal WIFI/Bluetooth may be supported on this board? (Intel Wi-Fi 6 AX201)

Thank you Maldon. That worked. Is SMBIOS ok at iMac20,2? Thanks again.

Thank you Maldon, unfortunately upon boot, I'm getting this error. Thank you. IMG_6864.jpeg.zip

Greetings Maldon, following your guide, I'm running my new setup with your OC here, and any assistance in patching would be much appreciated. Didn't know if I should use the DSDT you posted, as my configuration is slightly different than your post. Thank you so much!

That was the answer, thanks again!

Greetings Maldon, Purchased a 2nd system identical to a unit that you patched. That system runs perfectly, however using your patched DSDT and EFI, this system boots to a black screen without -igfxvesa. Bios settings are identical, however connection between monitor and PC is HDMI-HDMI, as opposed to VGA-DP. Any assistance on resolving this issue would be most appreciated. Thanks so much!

Excuse the delay... Wanted to thank you once again. This build screams. Much appreciated, Maldon. Your expertise is unparalleled.

Thank you for your patience. Simply like this? Screen Shot 2020-09-16 at 11.50.24 AM.zip

Greetings Maldon, System boots with your appropriate OC Folder, however wake from sleep kp's. Any DSDT tweaking would be much appreciated. Thank you very much! Ryzen 3900X Sapphire Radeon Pulse RX 580 MSI B450l Gaming Plus AC Catalina 10.15.6 Send me ssprod's-iMac-Pro.zip

Did the trick, thanks so much Maldon!

Thanks very much, I'm booting successfully with your DSDT and the folder you've recommended. What would be the appropriate smbios to use (GenSmbios app)... 18,3? Much appreciated.

Thanks Maldon, I'm afraid it's still booting to a black display. CSM is off and the attached SendMe contains your DSDT. Thank you very much. Gigabyte Z390 Designare i9-9900 SAPPHIRE NITRO+ Radeon RX 5700 XT Catalina 10.15.6 OpenCore Send me ssprod-iMac.zip

Greetings Maldon, I've worked on this config before, however never used OC nor this graphics card. Install works with my 580 but goes to a black display with my new 5700XT. Any assistance in rectifying this issue would be most appreciated. Thank you very much!

Thanks so much!

Maldon, thank you for your suggestions. Re-seated the Ram, updated the bios. Was able to complete installation. Please find "sendme" attached. Thank you very much! Send me MacPros-iMac-Pro.zip

Unfortunately, same KP, thank you for your patience.

Greetings Maldon... Using the appropriate Coffee Lake EFI, the system KP's almost immediately after verbose. Any thoughts? Thank you very much. Asus Prime Z370-Aii 8700k Radeon RX560 4GB 10.13.6 EFI.zip

Thanks very much, Maldon. Everything is solid, even wifi with itlwm_v1.0.0_stable.kext and HeliPort.dmg

Greetings Maldon, Update: System now boots with Macmini8,1 and USBLegacy set to "on" in Bios. If Legacy is set to "off", system KP's. I'm dreaming but is there any way to get iNtel WIFI working on this board? Thanks again for your continued support and expertise. Much appreciated! EFI+IOREG.zip

Thanks for your patience. Just before display, system goes black and reboots. Thanks again EFI.zip

Excuse my confusion. Not sure of the best method of adding this patch to the config. My apologies. Archive.zip

Catalina’s iMac.zipThank you!

Thank you Maldon. I require a video patch or is it contained in the DSDT? System still does not boot without -igfxvesa. Thanks again.
