I've decided to use from time to time my "old" Power G5. I've deleted everything reinstalling from disk and creating a new account.

When I try today to connect to the internet ask me for admin name and pass. The entered are good for enter into the account which is a standard one but without admin privileges.

Searching in the communities I find an answer suggesting to someone who deleted by mistake his admin account to enter following path in terminal:

dscl . -read /groups/admin GroupMembership


He got a bad answer: Error..etc . In my case the answer is:  root. I suppose that as root I would be able to give admin privileges but I do'nt know how to do it.


Any halp will be appreciated, thanks i advance.

    Reset OS X Password Without an OS X CD...




    It'll boot like a newly setup Mac, but all your stuff should still be there once filling out the stuff.


    The new Account will be admin.

    Thank you, I've read the same answer in another post but an Apple document says:


              - You cannot enter single-user or verbose mode if the computer owner or administrator has                        enabled Open Firmware Password Protection.


    Tested and confirmed, after reboot open in Finder again. Rebooting from disk is even not possible.


    Is it possible to use those commands in terminal direct?

    Oh, you have open Firmware Password on top of this!


    I think they would work in Terminal, but not sure how that would work in the present situation. Might lock you out for good.


    Firmware password protection in Mac OS X ...




    It would block usage of all the startup keys, like C, N, T, D, CMD+s, CMD+Option+p+r, CMD +v, Option, and Shift, as well as booting from anything but the Hard Drive.


    Force Removing Password Protection


    1) Add or remove DIMMs to change the total amount of RAM in the computer.


    2) Then, the PRAM must be reset 3 times. (Command + Option + P + R).

    Ok, I will try but since this is a major enterprise for me ans it is late enough here in Spain and i have tomorrow one to one Final Cut formation at AppleStore I will let you know tomorrow the results of this battle  :-)


    Thank you very much!

    OK, good luck on both!

    Success! Thanks for your support, both technical and emotional.


    I forced to enter in Open Firmware mode by pressing the start button continously, after follow your instructions and trying to reset PRAM. In the open Firmware I followed


    http://support.apple.com/kb/TS1812?viewlocale=es_ES  to reset NVRAM and Open Firmware.


    Than, still not able to be an admin and ignoring how to do it in terminal I could at least reboot again pressing C and get access to password utility. I've changed both passwords, my account and root... It can be dangerous but it works. Now, when working with the G5, I will learn to be root and myself at the same time.

    I'm happy now. Enjoy yor time and best regards

    Great news, good work, thanks!

    As a logical happy end in Prefs pane > accounts I could assign admin privileges to my standard account. That makes feel better.
