Hi, I am using Macbook Pro retina with 10.8 Mountain lion. I am new to Mac OS. I just want to know is there anything on mac os like " password reset disk " (as in windows.) In windows it allows you to save a file on some pen drive and it doesn't matter how many times you change the password, if you forgot the password just insert the pendrive and you can reset the password. Now I know my administrator password to login to my mac, but what if I forgot? Is there anything like that on Mac OS. Thanks.
