I need 2 reset my macbook air i want to take all passwords off..

to reset without any admin passwords, you'll either need a boot disk or use command line to reset the admin password

use the factory disc provided

Maybe the owner's manual might make reference to some sort of reset option. If the password is a simple 4 digit code, then guess it. Most peoples' passwords have something to do with the person who set the password, I.e. a nickname, name of a family pet, anniversary date, etc.

If it is the firmware password protection, then the only way to have that reset is by taking the macbook to an authorized repair center or Apple Store.

If the issue is with the operating system password, then you'll need the original system CD that came with the Macbook. Power-on the Macbook and immediately insert the system install disk and then press and hold the C key down until the circular icon stops spinning.

You'll then be able to select Disk Utilities that you can use to reset your password.

if the password is set on the firmware level you will need to take it to the apple store.
if you have the restore usb stick you can boot off it by holding the d key when you power on your mac.
after it starts up from the usb stick you will go to utilities at the top and click reset password.

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.
