Does Thunderbolt work?

If you can share EFI, please send me as well.

 

[AJaxom]

EFI attached with serials removed.. USB 3.1 does work but haven't tried it with any Thunderbolt devices.

Gratz pal. Would you mind telling how you made sleep+wake work? My build does sleep+wake, but wakes only through the power button (no keryboard/mouse response). Thanks!
