So i was having some troubles with connecting to the internet and i was told to reformat the *******. so i was reinstalling os x on my macbook pro and now i cant edit my trackpad because i dont have one installed...

i didnt have this problem when i first set up my computer and i cant find anything about it on the web... anything about it or drivers for my track pad.

FURTHERMORE now when i use my volume control on the keyboard instead of changing the volume it brings up the "dashboard."

what have i done?
