    no admin. password, old school computer
    I purched a used macbook from a yard sale. this was suppossed to be an exwifes computer that he didnt know the passwords to. So i figured that I would just buy the restore disc and reset every thing including passwords. well when I put the disc in instead of any thing prompting me to reload. A lock with a place for a password pops up. can I get around this. I think this might be an old school computer with the extra protection so you cant reboot the computer. Is there any way I can reboot this?

    Ok so try this ... Put the Restore disk in ... reboot the MacBook right after the ding press and hold the C key ... till the Apple comes up..

    Then you should be able to navigate to where you can change the passwords you need to.

    I tried that . It just displayed the place where you log on. oh corse I cant log on. when I place the disc in I had to hold the opion key. So I also tried to press and hold the opion key till the apple came up. Th lock came up. Its a plaine black lock with a box under it then off to the right side of the box is a black circule with a arrow in it that you click onto after you put the password in.

    ok so you have a firmware password set ... I have not tried this but looks like you will have to change what the system sees by removing one of the Ram modules .. from the battery compartment.

    I hope you have 2 sticks of ram in there

    After removing / adding more RAM than before, Turn on the computer and immediately reset PRAM by holding the Command-Option-P-R key combination. Press the keys until you've heard two successive startup sounds.
    Open Firmware password protection should be now disabled.

    Try and boot to the disk again.. clear or reset the passwords ...
    Shut down the computer and return it to its original RAM configuration.

    and see if it boots.

    Imac 27" Retina 3.3GHz, 512GB Flash, 16GB memory, OS X.11.4.
    And if it does not return it. Firmware Password Protection can be the very devil without the password and as you have found you cannot even boot from the system disc.

    Specs:
    15" Macbook Pro 2.0Ghz i7 8GB AMD 6490M 256OCZ Vertex 4 SSD | iPhone 5S 16GB
    Try this one:

    Remove the AC Adapter

    Remove the MacBook's memory

    Put the Memory back into the MacBook.

    Plug the MacBook's Power cord back in.

    Press the MacBook's Power button, and then immediately hold down the Apple key, the option key, the P key, and the R key - using both hands, and all four keys down at once, and hold those four keys down, until you "hear" the MacBook chime three times. Should take 30-40 Seconds between each chime.

    If not, you might need to take it into an Apple store and chances are they're gonna ask for proof of purchase.

    It should work. Just remove one module of memory, not both. Then follow the directions to reset the PRAM/NVRAM. The firmware password should be gone.
    Then reinstall the module you removed and see if you can boot back up normally.

    If the firmware password still persists, go back in and try removing the other module - but only one at a time. Reset the PRAM/NVRAM again.
