    I got this old school G4 and went to go start it up and there's a big ol silver lock on the screen... Wait about 15 seconds and the Finder guy face ;) will flash for a millisecond and it will unlock... then it will lock itself in another 15 seconds. :confused: WTF?!?! :confused::confused:

    A few helpful links:

    More generally, try this and this.

    More specifically, it looks like you've got a Mac with an Open Firmware password. Helpful hints here and here

    I understand, but mine doesn't have any field to enter anything in! The padlock flashes from locked to unlocked.
    What is that supposed to be http://google.com I don't know why it's censored. :confused::confused:

    Did you try resetting PRAM as suggested by the links above?

    When powering on, hold Cmd+Option+P+R. (Tricky to do with one hand on a qwerty keyboard, but I just did it the other day). Keep holding until you hear the startup sound a SECOND time. You should then be able to log in normally.

    BTW, the way you would have gotten the field to enter something in was to hold option I believe.

    Remove one bank of memory and restart. Shut down and replace the memory. If it is an Open Firmware password, that should clear it.
