Is there any way i can reset my mac admin password with a tool like chntpw. Booting from a Mac OS X Install CD is not an option, since the firmware password is set. Are there any simple ways of doing this?

Thanks

There are a few ways around even a firmware password, but they take time.

A short summary of the instructions could be useful. The webpage might dissapear. –  vonbrand Feb 28 '13 at 10:41
    
Hi, i don't actually own a Mac, i have a cloned hard disk image. I just want to know if i can reset the admin password without booting it, like you can in Windows if you have read/write access to the HD –  Jack Renshaw Feb 28 '13 at 12:08
