[OFF TOPIC] Yosemite 10.10.3

Just installed this update a couple days ago, came with a new app (Photos). I’ve been having some problems, three-finger lookup no longer works just shows a blank box and my keyboard stops working randomly so I have to restart. Going to take it in when I have time but I wanted to see if anyone else has had issues.
