Using the provided latest DSDT with my already working SSDT-PM, the system boots fine and works, PM is also correctly working. What the DSDT not include in PCI overview is the Atheros Ethernet Card, but it's working, so no worry's ThunderBolt 3 hotplug via SSDT still breaks my Avid Card, super weird.

With you're DSDT do I still need to activate SSDT-DTPG, when trying to test out the SSDT for Thunderbolt HotPlug ?

Ok, thanks, will try this one out, later today. What did you change from the first DSDT you gave me ? Can I use the already made PM SSDT from in my EFI folder or do I need to redo it with this new DSDT?

Here you go NEP2B_Studio_EFI.zip

Hi, I'm still running OC 0.6.6 but for some reason it's telling OC 0.6.7 What about the other SSDT's in ACPI ? Just disable them ? Btw, the OpenCore guide is telling to let 'RebaseRegions' to false Booted via an external USB drive to test it out, CPU is stuck at a frequency of 800 mhz

Hi @MaLd0n Here is my dump of my system. Please ignore for the moment the ThunderBolt Card inside the system. I will still use the SSDT to inject if it ever works to get the HotPlug to work with my ThunderBolt Chassis and Avid HDX Card. Send me NEP2B-Studio.zip

Ok

Ok, it connects indeed on UPS0 but won't load the Driver for the card, so if we can find a way to force load the driver ?

Ok, I see, you're SSDT is having it in the file. Will try it again! Then, if the device wouldn't connect correctly is their a way to force connect it to that specific path ?

Hi, If you look at both screen shots you see that on the MacBook Pro you have: DSB1@1 =>IOPP ==>UPS0@0 ===>IOPP ====>pci-bridge@1 =====>IOPP ======>pci11af,ef70@0 (Avid HDX Card) And on the Hackintosh: DSB1@1 =>IOPP ==>pci-bridge@0 ===>IOPP ====>pci-bridge@1 =====>IOPP ======>pci11af,ef70@0 (Avid HDX Card) So I'm feeling there is going something wrong or should be abled to get changed. On real mac you got 'UPS0@0' while on Hackintosh 'pci-bridge@0' Is this something we can get fixed ?

yep, if you use the HotPlug SSDT the Card can't find it's correct driver for some weird reason

Hi, I attached 2 screenshots from my Avid HDX Card in the Expansion Chassis. One from on my MacBook Pro where it works and you can see it's recognized in the IOREG. The other one is from on the Hackint0sh WITH SSDTs Injected'. I feel it's like not connecting to the correct sub ports. Avid HDX.zip

So, Cold Boot 2 ports are connected: Port 1: Sonnet Breakout PCIe Box Port 2: Tb3 to Tb2 -> Tb Harddrive Cold Boot System Boots fine, Then the warm boot, OS loader takes for ages to load the OS, but got stuck at the 100% loading bar.

I’m going to my studio, so I will try it for you if both ports work without the SSDTs injected.

Hi, didn't had time yesterday for further testing, I had an recording session so I went for working Thunderbolt without SSDTs. Just needed a Warm reboot for it to work. But Thursday I have time to get more into details

The Card I'm using is an Titan Ridge 2.0 Card, so that's TB3. The Expansion Chassis is also TB3, the card inside it is still an PCIe 2.0 X4 if I'm not mistaken!

Not a problem for me, because it was just to get an PCIe Expansion Chassis. But only problem remains that when the SSDTs are injected the Card doesn't work. SSDT_Injection_Problems.zip What do you mean with one for tbh2 ?

HotPlug works, but only 1 port can be used. When using both, non works. When using this, I see the titan card in my PCI tab, but now my Card is in the list but telling me not having a driver installed. If I disable the SSDTs I can get the Audio Card working

So this is with you kind SSDT injected into the system. NEP2B Studio TB3HP SSDT.zip

BTW Do I Need a DSDT Patch ?

Hi, No options in the BIOS, same as the MacPro 5,1 I guess I need to use an SSDT to get HotPlug working. But when I look at other Guides, you need to replace RP05 / RP21 in the provided SSDT but, that I don't see in my IOREG HackinDROM

Hi, For the test now, I'm using an 'Sonnet eGFX Breakaway Box 550' with my 'Avid HDX Card' installed in it. Thunderbolt Cable is connected to the 'TB3 Port' closest to the 'DisplayPort'. When booting from a shutdowned system the 'External Box' lights up and when starting my Audio Program that takes advantage from the card inside, isn't recognised. When rebooting the system and starting the software, the card is recognised.

Hi, So when I saw that it was possible to run an Thunderbolt 3 / Titan Ridge Card in a MacPro 5,1 with a flashed firmware, I thought, nice should try that out on my 'older' system. So I bought a Titan Ridge 2.0 card and flashed the firmware, but when putting it into my system I had no succes System specs: Z77X-UD5H F16J Mod 11 i7-3770K 32GB 1600 mHz DDR3 (Quad Sticks) AMD Radeon Pro WX7100 (PCIEX16 Slot) PCIEX8: Avid HDX Card [Pro Audio Card] or GC-Titan-Ridge-2 PCIEX4: PCIEX4 Adapter to NVMe Drive PCIEX1_1: Sonnet Allegro FW800 PCIEX1_2: Empty PCIEX1_3: Apple Broadcom BCM943602CDP – 802.11 a/b/g/n/ac with Bluetooth 4.2 I was putting the card in the slot labeled PCIEX4, but yesterday I had the idea, why not trying in the PCIEX8 slot. BAM the card shows up on the system. Now, when booting up with an Thunderbolt SSD connected to it the drive is working but HOTSWAP not. If I'm correct you need a SSDT for HOTPLUG to work. But when looking at 'IORegistryExplorer' I see totally other things then in Guides about Thunderbolt I saw. Can you have a look at my system? I attached the IOREG with my default 'professional Audio Card in PCIEX8 Slot' and one with the 'Titan Ridge 2.0' in the PCIEX8 Slot. I put some screenshots in a second zip from the Thunderbolt cards working as it is now NEP2B_Studio_IOREG.zip NEP2B_Studio_Screenshots.zip

Hi @MaLd0n, I have a question. I'm still running an Z77X-UD5H Board with HD4000 and an 3770K. Currently it's running on Mojave with OC 0.5.8 I use the modded BIOS version: GA-Z77X-UD5H BIOS F16 mod11 I'm currently using an DSDT I found on the internet that works, but don't know if it's complete. What do I need to provide for you to check it ?
