ADD During the Boot Process? Here’s your solution…

Maybe you’re old school, or are using Mac OS X because of it’s UNIX pedigree, or perhaps want to remember a little bit of the DOS days, but prefer the Aqua graphical interface. You’re itching to see something during the boot process instead of some half-eaten apple, or a fanciful graphical box. The first thing you can do is replace your hard drive with an Solid-state disk (SSD)– or buy a new MacBook Pro with and SSD– no latency to slow down the boot process, and it minimizes the graphical screen entirely.

Perhaps that’s not an option–or you just want to see text during the boot strap cycle. Well, you’re in luck– it’s easy. If you just want to see it once, for old time’s sake, just hold the option key down and hit the letter ‘V’ when you turn the computer on. Like it? Got your fix? Good, then the next time you boot, it will be just like it always was. Like it? Want to see that every time? Well, here’s your solution.

Open a terminal and enter the following command:


$sudo nvram boot-args="-v"

You’ll be prompted to enter your administrator’s password– do so.

Once you complete the command, you’re set! This will tell the operating system (Mac OS X) that the non-volatile boot parameters (boot-args) are to boot up into Verbose mode. It will remain this way now, every time you boot, unless you clear NVRAM or reset the boot-args parameter (e.g., boot-args=””).

If you’re not terminally ADD, your Mac actually boots, but you can’t access the interface, this may be useful as well. Simply connect to the Mac via SSH (assuming you have SSH enabled) via another computer, and enter the exact same command.

Wah-la! Now your ADD gene will be occupied during the boot process.
