Why is the Force Touch "taptic" TrackPad not clicking/selecting on 2015 MacBook Pro? I have a 2015 MacBook Pro running El Capitan with the new taptic force touch trackpad thing. Which, I must add, is fantastic!

However, this morning I started it up to discover it would not click/select anything. What is this madness? How do I fix it? How do I stop it happening again?

Things that work:


Typing with the keyboard.
Moving the mouse around.


Things that don't work:


Touch to click (I had enabled that setting)
Press to click (track pad makes a clicky sound but does nothing)
Deep press (track pad makes double clicky sound)
Two finger press (for right click)


Have Tried:


Restarting the Finder
Restarting my Mac
Making sure it is pugged in at the wall
Vigorously tapping the trackpad in frustration
Using expletive language


Unfortunately, I had no success with the above.

Previously, there were no issues with the trackpad. This mac is relatively new, I cannot think of any installed software that could be causing this issue. Any help much appreciated. Thanks.
My trackpad (MBP Early 2015) was working, but there was no haptic feedback, or any indication that force touch was working. Other functions (trackpad, single tap, scrolling, etc.) were working. Here's what my settings looked like:


For me, it was fixed somehow by an SMC reset with the charger disconnected, while powered on. Basically, I pressed Control + Shift + Option + Power button. The system instantly shut down without warning. Force touch and haptic feedback were back when the system turned on.

Do I recommend this? No. It's an unclean shutdown. Did it work? Yes it did.
