How do i bypass macbook air master password without a disk

SOURCE: how to reset the master password for g4 mac powerbook ?

1. Obtain a Mac OSX install disc (buy one from apple or try Ebay) 2. Insert the disc then click on the "Install Mac OS" icon. Then click the restart button. 3. DONT INSTALL! Just click through enough of the windows to get to the regular set of choices on the menu bar. One of those choices is UTILITIES and one of the choices there is RESET PASSWORD.
Simple, but you should know that anyone with a Mac OSX install disc can gain access to your computer.

If you don't know your username before you type the dscl command type: ls /Users and find your account and use that name for the user name.

I suppose you have a l&te 2010 Macbook Air... - Plug the Macbook Air to a power outlet
- Plug the Macbook Air USB software reinstall drive that came with your Mac (in the little black cardbox) in any USB port - After the initial screen, go to "Utilities" in the menu bar and then choose "Reset Password" - Follow up the process and you should be OK.
Hope this will help. Cheers.

Hi there,
It sounds like you've just upgraded from 10.5.7 to 10.5.8 - this is a known problem that's totally fixable, don't worry! This should sort you out:

1. Lot in to your account (You are an administrator, you said?).
2. Open up Terminal (located in /Applications/Utilities/Terminal). If you haven't used it before, don't panic - it's not nearly as scary as it looks!
3. Enter this code, exactly as written, but replace (username) with your short username - all one word: dseditgroup -o edit -p -a (username) -t user _lpadmin
4. By the way - there should be no brackets in the code. For example, my username is barnabywalters, so it would be dseditgroup -o edit -p -a barnabywalters -t user _lpadmin
5. Try installing the software again, with your password. It should work this time!

font.f1 {font: 12.0px Helvetica} Thanks for asking your question with Fixya Support. I will be glad to assist you.


Here are some steps you can try to resolve the issue:

• First, hold in your power button for approximately 10 seconds to do a hard shutdown, if you have not already turned your Macbook Air off.

• Once your Macbook Air is shutdown, you will need to perform what is called a PRAM reset (Parameter RAM)

• Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously .

• Turn on the computer.
• Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.

• Now, hold the keys down until the computer restarts and you hear the startup sound for the third time.

• Release the keys and allow the Macbook to start up.

If this procedure does not work, then I recommend you take your Mac OS X installation disc and perform a Password Reset.
-----------------------------------------------------------------------
Don't worry, this procedure will not delete any files on your Mac OS X volume, it is just a simple password reset utility which can allow you to fix any password for your user account.

BOOT TO TIGER/LEOPARD DISK-
• Place your installation Disk (Tiger or Leopard I presume) into your drive and
allow it to load.
• Restart your Mac
• As soon as you hear the Apple Chime, press the "C" key on your keyboard
and hold it.
• You will see a White Screen, Grey Apple first, do not release the C key until you
see a Spinning gear.
• Once you see that Spinning gear, release your C key and allow the disc to continue loading

- RESETTING ADMINISTRATOR PASSWORD-
(Works for both Mac OS X 10.4 (Tiger), Mac OS X 10.5 (Leopard) and Mac OS X 10.6 Snow Leopard)

• When the booting to the Mac OS X disc is completed, you will now be in the
Installer environment
• Enter to next page, look up on upper left corner you should see "Installer" near
the Apple menu.
• Two spaces over you should see Utilities. Click Utilities>Reset Password.
• Select your user name from the drop down list and reset your password.
• When you are done, simply exit the Reset Password and Installer and reboot.
• At the Login window, enter your new password and you should be back into your home profile.

Let me know if this proves resourceful for you, Thanks!
