I tested the V6 SSDT for GC-Maple Ridge yesterday (with the ACPI patch for _PTS to XPTS) successfully with two different Thunderbolt 3 docks. It’s a bit tricky to activate hot plug, as follows:
- Boot system without the dock connected, and log in.
- Open IORegistryExplorer and scroll down to RP05.
- Now plug the dock into either of the two Thunderbolt ports.
- It won't work yet.
- Wait 5-10 seconds.
- Disconnect the Thunderbolt cable from rear IO panel.
- Connect Thunderbolt cable to the otherThunderbolt port.
- Wait 10-15 seconds. It may not work yet either.
- If it does not connect, remove Thunderbolt cable from rear IO panel and connect it back to the first Thunderbolt port.
- Wait 10-15 seconds. It should connect...
The controller may or may not wake from sleep.
