How to disable trackpad tap completely? Force only actual clicks
With the latest software update 10.12.6, the option to disable "tap to touch" works now.  It's in the trackpad options.  Before the update this did not work.
Funny story - after the updating the OS (months ago?) it was still forcing the tapping.  When I went into the trackpad options the box was unchecked, which didn't make sense.  For fun I clicked and unclicked the box, and now it's fixed.  Yay.
