@Floris497 sorry, misread your question. No I don't even get signal out without the patch :D
Maybe because of the last usb-c update from apple ?

Maybe.. I have no idea what they updated.. But it seems weird to me that it doesn't give signal before the patch.. That's what i don't get.. What type of connection are you using to the display? Only HDMI2.0 and DisplayPort can do 4k@60Hz (USB-C monitors use native DisplayPort capabilities of USB-C port)

I am using a usb-c dock, that has display port out, display supports dp1.2.
And then the apple adapter with HDMI (don't know if it supports HDMI 2.0).

The apple one is NOT HDMI2.0 (most probably HDMI1.4a) Why the DisplayPort dock does not output 60Hz.. I have no idea. Look if your monitor has MST SST settings (sometimes referred to as DP1.1/DP1.2) It can be the case.

@Floris497 yes, the monitor has a d1.2 and it's enabled. But maybe the dock is doing something weird.
I should try to do use a usb-c -- > display port cable!
