Intel iMac, Open Firmware Password Protection and booting from CD

Question

I have an Intel iMac I'm setting up for use in a public library. I want to prevent single user login with the Open Firmware Password Protection utility, but if I do, how do I boot from the OS disc, zap PRAM, etc? The OFPP page has instructions on removing the OF password, but it does not work on Intel Mac's. Also, is there an alternative way to prevent single user login?

Answer 1

No, you were right, I just misunderstood. Technically it's called single-user mode. But, you were right.
Anyway,
Since it seems that there might not be an answer directly related to your topic you could maybe give this a try.
In Simple Finder the user can not restart or shutdown. They can only sleep and log out.
The other problem, however, is if they log out then there are those Sleep, Restart, and Shut Down buttons on the login screen. Luckily, though they can be turned off.
So as of now, if some is logged in in a Simple Finder account they can not restart or shut down the computer in order to get into single-user mode. They can also not get into the Administer account since it is password protected.
The only problem I can see with this is that a person could do a hard shut down, hold the power button down until it turns off, and then boot up and enter single-user mode.
If you want to go ahead and do this, in order to get the computer up and running in the mean time, just post back and I'll be glad to help you set up a Simple Finder account.
