Ok so i was trying to change my dock theme, and i followed all of the instructions of replacing my dock files and everything. Now, there is nothing on my computer. It is just a blank white screen with no dock anywhere. I've tried resetting it many times and i've tried switching out the dock options, so its not that. I cannot change my background also. I've also tried to go in terminal and do "killall Dock" a few times and that didnt work. Any suggestions?
