Create a new admin on Mac os x

The Working solution for me was to create a new admin

you can create new admin like this by deleting a specific file.

You need to enter terminal and create a new admin account:

1. Restart

2. Hold apple + s down after you hear the chime.

3. When you get text prompt enter in these terminal commands to create a brand new admin account (hitting return after each line):

mount -uw /

rm /var/db/.AppleSetupDone

shutdown -h now

4. After rebooting you should have a brand new admin account. When you login as the new administration you can Easy delete the old one and you're good to go again!
