Yesterday, I need to install Microsoft Office 2011 into my boss Macbook Air. During the installation, it requested me to enter administrator password, but the Macbook is using autologin, locked and my boss totally don’t know the password. By searching the web, I found the solutions.
Here’s how to reset your OS X password with autologin enabled.
You can try this (try with your own risk):
Creating a new Administrator on Mac Os X:
The working solution for me was to create a new administrator account by deleting a specific file.
You need to enter terminal and create a new admin account:
2. Hold apple key + s key down after you hear the chime. (command + s on newer Macs)
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 /
shutdown -h now
4. After rebooting you should have a brand new admin account. When you login as the new admin you can simply reset the password or delete the previous Admin account.
I have done it! After that, I can install the Microsoft Office as usual.
