Done. All ports are functional. Thank you so much Maldon!!

Thank you. Please find requested file attached. Optiplex’s iMac.zip

Greetings Maldon! System is running ok, however some graphics glitches make me suspect that I need to tweak DSDT or EDID, etc? Any help on this matter would be much appreciated. Thank you very much! Dell Optiplex 3020 i3-4160 HD4400 Graphics 8GB DDR3 Send me Optiplexs-iMac.zip

Based on your suspicion, I used AppleALC 1.4.3 with i.d.=27. Audio is now working. Thank you for your help Maldon! I'm posting my final EFI, should anyone else want to use. Thanks again. EFI-Optiplex 3060 Micro-10.15.5.zip

Thanks for your efforts in tackling this issue Maldon. Interesting, the same speaker(s) that I physically connected to the audio out of the Optiplex is also bluetooth. Bluetooth is perfect audio, no issues. I also ran Windows 10 on the Optiplex, and no issues with audio at all. I'm attaching Aida64's Windows output of the audio hardware/id's. Thanks again!

Will any other codecs sub for ALC255? I've tried all of the i.d's.

Thank you! Send me Catalinas-Mac-mini.zip

Greetings Maldon, thank you very much, that seemed to do the trick. I have an audio issue.. with headphones, the mix is not "true", and when I plug in powered audio monitors, i'm getting a loud hum along with the audio. I have tried every layout outlined in the ALC255 Codec, with the same results. Any thoughts? Thank you once again. Most appreciated.

Hello Maldon, Did a fresh install of 10.15.5 with the same KP after wake from sleep. Wakes up to full desktop, then reboots. Failing a fix, would you recommend OpenCore as a possible alternative/solution? Thanks again. panic(cpu 0 caller 0xffffff800aa15f27): %22AppleHDAHDMI_DPDriver::setPowerState….pdf.zip Send me Catalinas-Mac-mini.zip

Yes.... used another display to test HDMI and this happens. Changed the cable, no difference. Thanks. https://www.dropbox.com/s/h1vaoqghfvxuxwa/IMG_6453.mov.zip?dl=0

Thanks again. System shutdown works. Unfortunately, sleep/wake/restart is still happening.

Thanks Maldon! EFI.zip

On 19,2, issues are the same. It might be of note that I'm connected to the display via DP because my monitor does not have HDMI. I've attached the details of the error. Thanks Maldon. Screen Shot 2020-06-08 at 10.30.52 PM.jpeg.zip

Hello Maldon, I updated to 10.15.5. Shutdown immediately restarts the system and sleep will wake but then restarts. I did disable hibernate after the update. Any thoughts? thank you very much! ssprod Send me Mac-mini.zip

Yes, that I don't use. Disconnect?

Greetings, Been using an HP Z230 with Maldon's DSDT patch for the last few weeks. All works well, except for some reason, on fresh boot, the system will just shutdown/restart. After that, it's fine.. even for days in sleep mode. Only on cold boot does it shut down after 30 minutes. I have attached a pic of the reboot details. Any advice as to a solution would be most appreciated. Thank you! HP Z230 i5-4570 HD4600 Catalina 10.15.4 Screen Shot 2020-06-06 at 1.50.39 PM.jpeg.zip

Many Thanks Maldon!

Thank You Maldon, worked like a charm!

Greetings Maldon.. any help in DSDT patching this bad boy would be much appreciated. I'm currently not getting any audio. Thanks very much. Dell Optiplex 3060 i5 8500T UHD630 10.15.4 Send me MacPros-iMac.zip

Greetings Maldon.. I've used the appropriate EFI for this configuration, and all seems to be running (sort of) well. "About This" displays as an 8950, but the GPU is a 7950. Don't know if that matters. Any assistance in DSDT patching would be most appreciated. Thank you very much. Gigabyte Z77X-UD5H Intel i5 3570K Radeon HD7950 Send me Catalinas-iMac.zip

Excuse my inexperience... When I use hackintool to patch EDID, I’m doing in HEX then entering it into CC under Kexts To Patch. It is still booting to a black screen. Am I doing something incorrectly? Thanks a lot.

thank you! It boots, but to only 5meg HD. I notice that the boot arg "-igfxvesa" is still there. Is that intentional, and would it prevent correct graphics even if I patched EDID?

Thanks very much, Maldon. Fingers crossed? Send me Catalinas-MacBook-Pro.zip

Thanks Maldon, same issue.. after verbose it finishes with a blank backlit display.

Greetings.. Using the appropriate EFI (w/SSDT), the USB loads then boots to a black screen. Any assistance would be much appreciated. Thank you! HP-17-x108ca i5-7200u HD-620 EFI.zip
