I've seen this happen twice now and still investigating but figured I'd ask here as well just to see if anyone has encountered this before. Using an AutoDMG built OS image, two different computers are exhibiting weird behavior when using the touchpad on the MacBook Pro (one is 2012 and the other is 2013). The only similarity is 10.10.5. It's a rather strange problem. Magic mouse works fine.
I'm not touching any preferences for the touchpad or any mouse for that matter. No changes in User Templates that would touch the mouse settings. No tablet drivers being installed either.
I'm wondering if anyone else has seen this behavior before.
EDIT: Forgot to clarify. Single click does not work, but double click does work. You can drag the mouse with one finger as well. And everything works fine when you are at the boot picker (holding OPTION at boot up).
