Mac

Reset Lost password

First up, you need to reboot your computer while holding the Command and the R keys down. Hold your Mac’s power button down for about six seconds, and it will turn off. Wait a couple of seconds more, and then hold down Command-R on your keyboard while pressing the power button again to turn the machine on. Keep holding the Command-R combination until you see the little spinning circle just below the Apple logo on the boot up screen.

Once your Mac boots, you’ll see a window with various options. Use your mouse to select Terminal from the Utilities menu, and Terminal will launch. Type in

resetpassword

and you’ll get a dialog box that will let you do just that. Choose the user you want to change the password for, and type in the new password twice. Hit OK, close the reset password window, and reboot your Mac.

To set it back (that .DS_Store on the Desktop is hella irritating), execute those same commands, but just switch that TRUE to FALSE
