My MBP came back from being repaired and it always boots up in verbose mode now. I opened Terminal and typed in sudo nvram boot-args= and it asks for a password. I don't know what it could be.. so I just hit enter.. and it comes back to the command line. Next, I check what mode the boot is in, it still says '-v'. How do I get rid of this? How do I reset whatever password it is asking for? Is it the firmware password? Thanks.
