Just open MaciASL app, it will open your system DSDT and save it as DSDTosxfr33k.aml ( not dsl scroll the arrow down)

Sorry got caught up back and forth from Menards buying fake Owls to place all around my house getting sick and tired of woodpeckers and squirrels.

MacIASL compile errors so I had to save as DSL in the zip I included the Hackentool DSDT.aml its also as System DSDT as far as I know?

Are these DSDT no longer native? Since OpenCore does it patching won't that show up in DSDT? I know clover will let you dump Native DSDT's from the Clover GUI but here you go for now.

I looked at some of the other SSDTs for the 10G Sage and I think some of them may need modification for my board Sage II?

Find attached DSDT from MacIASL as DSL and Hackentool DSDT as aml

Correct. MaciASL sees the DSDT "as patched."

For a native dump with Open Core: https://dortania.github.io/Getting-Started-With-ACPI/Manual/dump.html#from-opencore

Ok let me create a new dump so I get a native DSDT. Well I get an error file size and when I try the EFIshell method I get a write error could it be the EFI is secure? I need to figure out how to get the file under another /users/home/user or maybe flash drive. I'll put the ACPIdump file on the flash drive and run the command on the flash drive and see what happens.

Ok I see what is going on it keeps writing the DAT file over and over until it runs out of space and even though I had the path correct it wrote the files to the root of EFI. So I managed to get the Native DSDT.

Downloaded DiffMerge and compared Hackentool DSDT.dsl with the one dumped from OC efishell they are identical except for the 8th line about disassembly which is expected, somehow not sure how Hackentool can dump Native ACPI Tables from booted MacOS?

Edited Again:

MacIASL also is able to get Native (System) DSDT not sure how either?

Here is the Native DSDT from OC EFI Shell Dump as aml. Takes a long time to load in MacIASL its a huge file 767kb.

Here is an EFI adapted from yours above:
- new SSDT-X299-TB3HP with the same name ( XCH4 section according to USB.kext see below)
- added SSDT-VEGA64
- assed SSDT-X299-XHC (XHC2 / XHC3 section according to USB.kext see below)
- changed SSDT-RTC0 (for new bios)
- new USBASUSX299SAGE.kext ( only match with MacPro 7,1) : with XHC2 / XHC3 / XHC4 section added , XHCI unchanged)
I checked it but it's late here...
Try it with an USB stick and attach your IOREg
Thanks @Loloflatsix! It was late where I am too, but the workday here is about begin shortly. I’ll check it in a couple of hours and get back to you with an IOREG. Thanks for your efforts!

Thanks ! : all was told above I know...
My intension was not to have compiled DSDT...
Just DSDT quickly to see the PCIe entries. (It is the Sage II therefore different from the Sage I...)

@osxfr33k and other owners :

Here I attach the Pdf guide from Kgp to create or modify your own SSDT.

This method is simple and requires patience and time.

So I invite inexperienced people to read and try it.

Enjoy :thumbup:

In the Asus software repository, I found any chipset update for Windows (see attacched screenshot). As I run a dual boot system, what appens to my build on the macOS side if I apply these upgrades?

I think these updates are for Windows only.
