Other Reasons for Doing this:

OS:

Solution:

  1. Boot into recovery mode by
    • Shut down your Mac

    • When you see the Apple logo and loading bar appear, you can let go of Command + R
  2. Let it finish loading and you should now be in the recovery mode utilities screen, if not repeat the above.
  3. In the menu at the top start Terminal
  4. Now in the black Terminal window, type resetpassword and hit Enter (return)
  5. You should now be prompted to reset your password, enter your new password
  6. In the menu top left select restart to restart you computer and boot into Mac OSX
  7. Log in using your new password

    1. Yep. I’ve had to do this 5+ times since I installed Yosemite.

      Fixed now *I think*, replaced my Intel SSD (was supported by Mavericks) with a normal sloooow HDD.
