HELP ME PLEASE! So I turned on my MBP to see that my x key wouldn't work (I can't capitalise it either.) I restarted the laptop to see if that would fix it. After I rebooted my MacBook keeps typing a lot of x's in all of my iMessage conversations or if I open the iMessage program it spams x's in this content box. I am honestly mind boggled... I haven't spilled anything on my MacBook or damaged it in any way!
