I have the Open Firmware Password enabled, which prevents my machine from booting into Safe Mode when I hold the shift key at startup (as expected). As a result, if I want to use Safe Mode I have to boot up from my install DVD, disable the password and then reboot. Very time consuming!

I just read about a way to boot into Safe Mode (at Apple Support[/URL)] by entering the following terminal command:

sudo nvram boot-args="-x"

Has anyone tried this before? I'm a little hesitant to test it out in case I run into some sort of Open Firmware/Safe Mode conflict.

Extrapolating from [URL="http://hintsforums.macworld.com/archive/index.php/t-102785.html"]this thread
, it seems that this approach will allow you to boot into Safe Mode even with an Open Firmware password enabled. But I'm not going to test it on my system. :)

Worked just fine. To get back to a "standard" boot, just remove the -x from the command.
