OS X's Verbose Boot Process

Posted:
in macOS edited January 2014
I use the "Apple + V" key a lot to watch the Mac boot. How can I make a Mac boot in verbose mode automatically everytime? Is there a sys config file or firmware hack to do this?

    Good question...i am curious about that, too.

    Ah, an easy one!



    Open your terminal and enter this command:



    Code:


    sudo nvram boot-args="-v"







    Of course, enter your admin password when prompted.



    To reset this back to the old way, either zap the PRAM at startup or enter this command in the terminal:



    Code:


    sudo nvram boot-args=""







    Enjoy!

    It's impressive to see someone else who likes to read the details: not only the Mac boot sequence, but Buzzflash too. The desire to be informed is a good thing, in the best Steeeve sense.
