I tried that indeed; reboots, disable/re-enable the feature and it sometimes works and sometimes it doesn't. Very random imo. Only after signing AppleID out and in it works again. But then after a few reboots (i guess) it doesn't work anymore.

I have tried all the Titan and Alpine Ridge flashes and NVM33 works by far the best out of all the Titan Ridge ones. Also, I think you mean NVM23 for the Titan. NVM20 V1 is for the Alpine card while I got video pass threw I did not get Thunderbolt Hotplug. To get sleep to work I had to remove the THB_C cable and Jumper 3-5 pin.

Also, are the camera, mic, and the likes over TB? or are they over USB?
I was referring to this line in your post yesterday
"Now if only we could get a firmware for Alpine Ridge that works as well as NVM 33 works for Titan!"

The Apple TB display has only a single connector--TB1. I believe the camera, mic, and audio are USB devices incorporated into the Thunderbolt connection.

  • iStat Menus might not display the temps, fan speeds and voltages correctly. Instead, please try HWMonitorSMC2 from CloverHackyColor on GitHub.

Got it installed - and no read on the GPU. Everything else looks good. Do I need to configure anything for the GPU to be read? my iGPU is disabled in BIOS - not doing headless yet. When I run the config, it is not seeing the smcsuperio. It is in the kext folder.

there it is... cannot compile with that first few things that is in the dL file - there are other things in there too that don't work "stock". I just started deleting until compile passed the test to save - did I delete anything important? lol - I can hot plug :)
Generally not a good idea to delete items in an ACPI file. The only time Rehabman used to recommend that practice is when working on a newly-extracted DSDT that had errors in it.
An SSDT that is newly built for a specific purpose won't have errors in it or else the developer wouldn't have been able to compile and save it.
Are you using the current version of MaciASL? Older versions sometimes throw errors just due to the version of the tool.

Yes, used wrong MaciASL version. Fixed, replaced, and moved over the DROM info. Thank you!

You are now the question of which file do I need, and where can I get it from the Thunderbolt firewalls so that macOS recognizes it correctly. There are small other ways or SOIC8 SOP8 Test Clip + CH341A Flash BIOS USB Programmer for EEPROM 25CXX / 24CXX.

Can you link me that SSDT? Built in Alpine Ridge here, and I’d love to give that a shot too.
There are guides and information about flashing TB ROMs linked from Page 1 of this thread.
Post 16,393 is the repository of all the patched firmware. In that post also are links to the method for doing the flashing. Most of us have used the Raspberry Pi approach. The official recommendation is a Pi 3B or 4, but I have used a 2B successfully.

The most important thing is to THOROUGHLY read through the guide(s) that you will need to use. Then read them again, before starting. Then follow the guide(s) to the letter and take your time.

I personally used the pi3b+ with the "cheap" soic8 flasher. The method that worked for me was:

  • Disconnect power from motherboard (z390)
  • Connect jumper wires as suggested via guide with PI off. When PI comes on, there will be amber lights on the board. - try to read, wont work.
  • Remove 3.3v from pin 1 on PI (8 on flashing device)
  • Turn on PSU of board with 12v
  • Lights will be bright white and it writes the chip successfully. Verified
Disclaimer: I only followed the guide and had LOTS OF TRIAL AND ERROR. Only used board to "split" the 3.3v from pin 17. No capacitor/resistor. Just the PI, and the board that came in the box
