A FLAW IN the super secure Apple OSX enables a user to create an admin account without knowing an administrator password.

According to Hackmac, the security hole is really handy if you are a tech support person who has to deal with a Mac user who forgot that their password was “coldplay”.

Apparently it all takes about 5-10 minutes. You boot in single user mode. Gain root access by pressing Command + S (Apple+S). When the first shade of blue appears on the screen, hold it down until the screen turns black with white text. Everything will load.
Enter the command:

: /sbin/mount -uw /

Next, delete the file that tells your computer every time you start up that you’ve completed the setup by entering this commmand:

rm /var/db/.applesetupdone

Type, reboot. Wait for the setup screen to appear. Select “DO NOT TRANSFER MY DATA”. Choose your internet connection and network. Create a new local account to administer that computer which is different from the one you buggered up.

You should now automatically be logged into your new administrator account and will have lost none of your data.

All really simple and one which would give you total control of any user’s Mac, apparently.
