@pierpaolo2395,

It is not strictly necessary to enable Thunderbolt Bus. If the Thunderbolt devices you have can work without Thunderbolt Bus, then it’s simpler to use the simple Thunderbolt SSDT. Hot plug should work.

Again, the only factor to consider is whether your Thunderbolt devices work as you expect them to. If they do, then we should use the simple SSDT.

I'm having an issue with my Apple BCM4350C2 being nonfunctional since updating to 0.8.3 (originally using HackinDROM) in OS 12.5.1. The hardware is recognized but shows a 'NULL' address.

I'm beginning to suspect a hardware failure, as downgrading to my 0.8.2 backup didn't fix it, and using @CaseySJ's EFI upload from the 0.8.3 mini guide makes no difference. Curiously, WiFi seems to be working fine. (I've ordered an FV-T919, but while I wait for delivery, I figured it couldn't hurt to troubleshoot.)

BlueToolFixup (and the two Brcm kexts) makes no difference (they're on in this screenshot due to troubleshooting).

The machine has been working fine for more than a year. BT isn't critical, but I use Airdrop, Handoff, ApplePay, and Continuity quite often.
  • Z390 Designare (firmware version F8)
  • iMac19,1
  • Sapphire Radeon RX 480 8GB
  • 32GB DDR4 (2 x 16GB)
  • PCIe adapter for BCM4350C2 (vendor ID 0x14e4 for the adapter)
  • Crucial MX500 startup SSD
  • 3x WD Black series SATA HDD
  • 2x Dell U2415 screens with USB 3.0 hubs
Thanks!

ETA: Removing all USB devices makes no difference.

We need to uncheck the last ACPI patch ("_E2C to XE2C") and add this one:
  • Find: 5F 4C 36 46
  • Replace: 58 4C 36 46
  • Comment: Change _L6F to XL6F
Please post a screenshot after making this change, then reboot and see what happens...

Given the TB3 problem solved, how can I fix the iGPU problem?
Even patching the connectors I can't get video via DP / HDMI on TB3
I don't know why I can't even get the integrated HDMI and audio from HDMI / DP to go

@mustang.dvs,

Good write-up of the problem! My first thought is to perform a CMOS Reset as follows:
  • Shutdown the system
  • Flip power switch on PSU to OFF position
  • Use a flathead screwdriver to short the two designated pins on motherboard (refer to manual if needed)
  • Power back up
  • BIOS parameters will have to be re-configured; start with Load Optimized Defaults, then configure the other parameters
  • Boot macOS and check Bluetooth again

It would be best to describe the problem -- and any procedures you've already tried -- in this thread:

After the CMOS reset, I have a new problem: it doesn’t progress past the Apple on boot (no progress bar; I reset the BIOS settings twice using the guide at the beginning of the thread, just to be sure I hadn’t missed something)
Here’s where it hangs with Cmd-V held down at boot:

ETA: I get the same when booting from a freshly downloaded 0.8.3 EFI USB drive and when trying to boot into either the Catalina install USB or the 12.5.1 recovery partition, so I’m guessing it’s a BIOS misconfiguration, but I can’t see where I might have gone wrong, though it has been ages (and one bout of memory-flextime long COVID) since I messed around under the hood?

This most likely means that Boot —> CFG-Lock hasn’t been disabled in BIOS. We must disable it.

I’m using BIOS vF8, which doesn’t have CFG-Lock in the BIOS Boot settings.

This may be a good opportunity to install BIOS F9g in which CFG-Lock is disabled by default. The file can be downloaded from here:

I have corrected the rename as per screenshot

the TB3 part is loaded from the PC is OFF

the TB3 device does not detect me in the system info


From the PCI list, it loads the TB3 components for me, however by unplug / plug, it no longer loads the components.

IOREG attached.

(With another EFI where I use external DTPG, with SSDT Tb3 v1, Hotplug work stable only with the first Rename)

Also the DP / HDMI port via Hub TB3 does not work for me
Here are two more experiments to try:

Experiment #1:
  • Replace SSDT-TbtOnPch-ThinkPad-T480-OC-V2.aml with the new version attached
  • This one requires:
    • Find: 5f 4c 36 46
    • Replace: 58 4c 36 46
    • Comment: Replace _L6F with XL6F
  • Reboot and test Thunderbolt

Experiment #2:
  • Uncheck V2 and install the new V3 attached below: SSDT-TbtOnPch-ThinkPad-T480-OC-V3.aml
    • This means (a) copy file into EFI/OC/ACPI and (b) add new entry to config.plist --> ACPI --> Add
  • Uncheck the previous ACPI patch ("Replace _L6F with XL6F") and use this one instead:
    • Find: 54 42 4E 46
    • Replace: 58 42 4E 46
    • Comment: Replace TBNF with XBNF
  • Reboot and test Thunderbolt
