1. Reboot
2. Hold apple key + s key down after you hear the chime.
(command + s keys 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 /
rm /var/db/.AppleSetupDone
shutdown -h now

4. After rebooting you should have a brand new admin account. When you login as the new admin you can simply delete the old one and your good to go again!

you cannot install new os if you have a bios password
and flashing yr logic board, is hardware work, I don't think yr able to do it

BUT try those steps
1- try to exchange yr ram with different ram and then try those commands y tried
2- if u have 4g ram for ex, try to put only 2g ram and try yr command
if none of those doesn't work
send me image of the screen u getting

what macbook air? is the password you want to reset a efi password?

[stebel]

how much chances is there to reset the bios password

[iNemesis_d]

@nirav. I think he has an EFI password (firmware pass). This is hard to remove on macbook air ( even the exchange or remove of Ram wont work). Only way to do this is to take out the bios chip out and solder an new one on it. Not an easy task to do....

according to my info :

There is facility to setup a bios passcode in macbook air.
This is probably the administrative password .

So for admin pass you need a installX OS dvd*



Boot from the Mac OS X installer disk by inserting it into the Mac and holding down the “C” key on boot
Select your language preferences and then under the “Utilities” menu select “Password Reset” (it may say “Reset Password” instead, depends on the version of Mac OS X)
Select the hard disk that the forgotten password is on, then select the username of the forgotten password, you’ll then be asked to select a new password
Reboot as usual from the hard drive, using your newly reset password as the login!

You can use USB DVD Drive because Air don't have CD/DVD Drive

Boot with Option key held to display the boot menu's firmware password prompt.
Press Control-Option-Command-Shift-S to reveal a 33-digit hash (mixed letters and numbers) that contains an identifier for your specific motherboard and the Atmel chip used for your system. In this hash, the first 17 digits are an identifier for the system's motherboard, and the last 16 digits are a hash for the password.
Submit the hash to Apple, where someone will put it through a special utility to create a keyfile that is specific for your machine.
Place the file on a special USB boot drive and hold Option to load the boot menu and select this drive.
The system will read the file and properly reset the firmware password stored in the Atmel chip.
This process may seem easy enough, except that the utility for creating the keyfile is kept at Apple so you have to go through an authorized service center, which will contact technicians at Apple for this service. Secondly, the Apple technicians will not give you the keyfile for unlocking your system, so you must get your system serviced to perform this step.

Apple's Firmware Password utility in OS X's Recovery HD partition is still used to set the firmware password on newer Macs.




Even if you were able to get the keyfile, it cannot be used on any other Mac system. The Atmel chip's serial number and motherboard identifier are factory-programmed, resulting in a pairing that is unique for your system. This is why the hash numbers for your system must be programmed into the keyfile, making it machine-specific.
Even so, there is one way to bypass the Atmel chip, which is to manually remove it and solder a new, unlocked chip to your motherboard; however, without precise reflow soldering tools and techniques, this would likely result in an unmitigated disaster that not only would void your warranty, but would very likely break your machine.
Coupled with Apple's FileVault full-disk encryption to protect data should the hard drive be removed, the firmware password in Apple's latest systems provides a very effective hardware security lock. Setting it up involves the same steps as for all of Apple's hardware, but these advances make it so that to change or remove it you need to either use the same firmware password utility and remember the previous password, or have it serviced.

GUYSSSSSSSSSSS, Please stop confusing the guy !!!!!!!!!!
commands R and S will not work in bios password,
only way to do it, is by flashing yr lojic board, which i doubt any can do that, unless its APPLE engineers GUYS( Genius ones too)
2- If you bought legally this mac book air, i recommend you take it to nearest apple store they will fix it for u

most of those macbooks with bios pass, are illegal in another word are stolen or what ever,
