If there’s a mac which has a password, which you don’t know that you need to boot into. Then you can do the below to create a new account and reset the other users password 🙂

Boot into Single User Mode and remove a setup file

• Restart the Mac holding down the Command+S keys, this will take you into Single User Mode and it’s Terminal interface
• You’ll need to check the filesystem first:

fsck -fy

• Next, you must mount the root drive as writeable so that changes will save:

mount -uw /

• Now, type the following command exactly, followed by the enter key:

rm /var/db/.applesetupdone

Hope this helps!
