Z490 & Z590 - Will Z590 ever have macOS Support ?

...

1. Yes
2. The hot-plug doesn't even work on windows.
3. Sleep does not work.

Do I understand this right?

• With original Maple Ridge firmware you simply applied these Device Properties to OpenCore:

• And Thunderbolt Bus got enabled?

a little cup of Champagne (French of course), after all necessary tests for all features, we will have deserved the bottle

LOL! Yes a little cup for now and hopefully a full bottle to follow soon!

With Napa Valley so close to me, however, my little cup may well be a lovely little sparkling wine from Carneros region! Technically, unfortunately, we cannot call it "Champagne".

P.S. I do enjoy French wine as well!

This patch is not enough. You still need to program the OriginalFirmware-Z590iTH4-test01.bin ROM from the post:

Z490 & Z590 - Will Z590 ever have macOS Support ?

I'm ready for testing. Have you a short Thunderbolt tree with AppleThunderboltHALType4 loaded with 2 previously defined patches? I can send you some additional patched firmwares based on your first native. First, you could flash @CaseySJ patched one's here.

It is now detected and loads the Thunderbolt drivers.

Understood -- therefore:

• This is the first time we have enabled Thunderbolt Bus on Maple Ridge by:
  • patching Maple Ridge firmware
  • and applying Device Properties

Current Issues:

• Hot plug not yet working
• Sleep is impaired
• ThunderboltSwitchType3 (not Type4) is invoked
  • Maybe Type4 is not yet possible with macOS

From IOreg files, I understand that OriginalFirmware-Z590iTH4-test01.bin file is needed to enable all thunderbolt tree.

Moreover, we can see Thunderbolt Native Host enabled on port 7 without a patched ThunderboltDROM (0x2C7 to 0x287) !

For hotplug, I don't see IOThunderboltIECSNub with subtree to identify PowerDelivery informations.

We also have new Thunderbolt switch named as IOThunderboltSwitchOS (instead of IOThunderboltSwitchType3) and a new property named as Product Description

Today I took a photo in daylight. This is what the test motherboard looks like.

It's good that I bought a package of chips.

That's some fancy footwork! Truly Mad Scientist stuff!

As I see that XHC3 is not enabled (No driver yet for XHC Maple ridge with PID 0x1138), you could try same patching to see what happen (be sure to have Thunderbolt USB enabled on BIOS):

Config.plist > DevicesProperties > New device (+):
Devices : PciRoot(0x0)/Pci(0x1C,0x4)/Pci(0x0,0x0)/Pci(0x2,0x0)/Pci(0x0,0x0)
Key: device-id
Value: EC150000
Type: DATA

I changed the settings in the BIOS:

"Native OS security for TBT" - Enabled

It is usually recommended to disable Thunderbolt security. And it would be a pity if this simple BIOS setting were responsible for hot-plug not working…

Congratulation for your dedication! Harnessing a SOIC8 socket to the motherboard was a rather extreme step.
