  3. Open up the terminal on your portable or computer and type the folowing command:
    nvram boot-args="-v"
  4. and enter:
    reboot
  5. Done.

Alway boot Mac OS X in Verbose Mode

To boot Mac OS X in verbose mode, you could hit Command+V during startup, which brings up the familiar white on black console. If you'd prefer to always see the system messages on boot, you can adjust the firmware from the Terminal with the nvram command.

To turn on Verbose booting, at the Terminal type the following:
sudo nvram boot-args="-v"

Disabling Verbose mode:
sudo nvram boot-args=

And to see the current firmware nvram settings:
nvram -p
