Important info (and question) on Open Firmware

[simX]

I don't know what I would've done if I hadn't had this forum here.

Remember how Apple released the Firmware Password utility just before they released OS X 10.1.2? Well I decided, for the hell of it, to enable Open Firmware security. The utility told me that the security would be in place on next restart.

So I kind of forgot about it until I restarted my machine. Needless to say the password that I supposedly put in did not work. I was ready to freak out until I remembered the Open Firmware thread on here. So I just shut down my computer, took out a RAM module, zapped the PRAM about 10 times (to make absolutely sure) and booted up my computer. Thankfully the open firmware security was reset to have none. *phew*

Lesson? First, don't mess around with security that you really don't need. And second, always know how to get around your own security. If you don't, someday you will screw yourself over. Thank god it wasn't today.

Now for my question: isn't there a way to enable open firmware security by booting up from your computer and holding down Command-Option-O-F or something, and then putting in some commands? Can somebody tell me exactly how to do this (the commands for the three levels of security, etc.).

Apple will not provide any support once you tinker with Open Firmware. If you forget the password, or otherwise mess-up in Open Firmware, you will render your computer completely unusable. To quote from another thread, "you might as well throw your computer in the river".

Funny, Apple is providing the Open Firmware Password utility now, so I am inclined to say that they must be providing support now. Furthermore, as I said in my original post of this thread, you CAN get around the open firmware password, so you shouldn't "throw your computer in the river". Thankfully I didn't need to resort to that.

Thanks a lot for the commands, though.
