[GAMEPLAY] New Update Ruined Gameplay on Mac

I'm not sure if anyone else has experienced this problem, but the first game I played after my update finished, all of my controls were horrible and not working. I couldn't use "y" to lock on to my champ; I literally had to click the minimap every time I wanted to see the screen. Also, my left click wasn't working. I had to rapidly click on the merchant about 6-10 times any time I wanted to access the shop. Same for spells. I would click and click but it was only about a 10% chance that the spell actually cast. Please look into this. Thanks!
