Mac in verbose mode (white text when booting up)

Setting up some iMacs today in our San Diego Adobe training office, and one of the macs was stuck in verbose mode. When it booted up I got this strange white text on the screen of the iMac. It was very strange to see a mac boot up "command line style" like a win-tel. After some serious googleing I found two commands you can enter in the terminal window to put your mac into or take it out of verbose mode.

To put your mac in verbose mode type

sudo nvram boot-args="-v"

in the terminal window

To take your mac out of verbose mode type

sudo nvram boot-args=””

in the terminal window
