    Hi All
    Im trying to reinstall Leopard on my iMac, im following instructions that say, put disk 1 in the drive and restart holding down C, but the problem is, it does not boot from the disc it just shows the disc on the desktop and when I click install it asks for "Admin Password" which it does not recognize although its the password I have always used for updates.
    Thanks for any help to get it to reinstall
    Chris

    I thought to get into the option boot mode is holding down the 'option/alt' button. I recently setup my macbook for sale and I reinstalled SL with the default DVD. I did that and it pop up with the DVD icon I chose that then use disk utility to erase the disc and start the install. Worked for me.

    That sounds like my friend's macbook. He works for some US corp that should remain nameless (hint: their business has something to do with bandwidth, video stream etc). He had the same problem when he wanted to reinstall mac osx. It will ignore the DVD and ask for password. Turned out his compnay had some ways to lock it down to prevent employees from modifying it. So did you buy it new or get it from someone 2nd hand?

    seems you did protect your Mac with a firmware password , thats the one you need to remember , maybe capital letter or something like that you forgot

    or simply take out 1 of the ram modules
    startup and hold down COMMAND+OPTION+P+R
    wait for the starup chime to sound 3 times
    release the keys and wait for the login screen do nothing there
    shut down the mac
    put the ram you removed earlier back in

    done efi or open firmware password should be reset

    can somebody correct me if i missed a step
