My Function keys are messed up. Volume & Brightness keys don't work!
So yesterday I successfully changed my Macbook Pro Early 2015 trackpad.
All the parts were put on right places and nothing left wrong. After I turned on my Mac everything was working perfectly including my new trackpad.
But! Then I found out that my Function keys don't work properly. When I press them they do work correctly, but they don't do the stock commands like turning the volume up, down, brightness, next song etc ... Instead my volume button takes me to the dashboard with a whole new commands for these buttons.
I have been into the whole keyboard options and have done almost everything like ticking off the mission control settings. Unchecking the F1, F2 as standard keys etc. Everything like this is done.
Still! I can't manage to get the factory commands back. I really don't know how this happened.
I have tried PRAM and these kind of things without any luck. Notice that all the keys do work and nothing is damaged on the hardware, because when I press them they do work but in other ways.
I didnt have this problem before the repair. It is difficult to believe that the repair may have caused this because all the buttons do work properly, but does other things.
Here is a SS of the USB settings.
Это хороший вопрос?
I was expecting to see the Apple Internal Keyboard / Trackpad entry under the USB devices listing it's not there! I've not worked on these newer models yet so that was a surprise. Looking deeper into this model I see they don't daisy chain the keyboard via the trackpad mechanically as they did in the older models as well as use the internal UDB hub connection. The both the keyboard & Force Touch trackpad must use a different connection to the system (PCIe?) You'll need to walk though the different hardware sections to see if you can find the interface. That might offer a clue here.
@alandoski have you figure out the problem? Because I have the same issue, I have changed the trackpad on my MacBook Pro late 2015, and my Fn key messed up.

I also cant use my Function keys, and even though I did the System preferences method, all my laptop does is make some sound every time I click on one of the F keys. When I click F12, something black with graphs and a zoom in/out button on the corner appears.
