How to Change My Password Without a Disk in a Mac Pro Book

By Jedadiah Casey

The MacBook Pro is part of Apple's line of professional-series laptops designed with higher class features, such as larger screens and faster internal components. All MacBook Pro computers run Apple's Mac OS X operating system. Mac OS X maintains separate user accounts, each with its own files, settings and passwords. You can reset the user account password without the MacBook Pro restore disc by entering commands in the Mac OS X single-user mode.

Step 1

Power on or restart the computer.

Step 2

Press and hold the "Command" and "S" keys immediately after the startup chime.

Step 3

Release the keys after the screen turns black.

Step 4

Type "mount -uw /" without quotes, and press "Return."

Step 5

Type "launchctl load /System/Library/LaunchDaemons/com.apple.DirectoryServices.plist" without quotes, and press "Return."

Step 6

Type "dscl . -passwd /Users/username password" without quotes, replacing "username" with the actual username and "password" with the new desired password.

Step 7

Type "exit" to restart the computer.
