hash unlock

To reset the firmware password on newer Macs, you must now follow these steps:
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.

If this is a hash why can't we unlock it by bruteforce?

Anyway if someone wants help with password or pinlock in Poland or Europe, simply email or PM me.

Thumbs up Unlock macbook firmware or icloud password

I see that there is great confusion about how to unlock the post 2010 macbooks for which the ram trick does not longer works. For 2010 -2013 macbooks the password is stored in the atmel chip which is eeprom ( non volatile memory)
There are 2 ways to unlock these macs:
The firs solution is to program a new atmel chip to replace the original one, this involves infrared soldering and is rather dangerous.
The newer and safe solution is to read the atmel chip with a programmer, find where the password information is stored and replace tha password with a blank one.
If you need further support You are welcome to contact me at sim_ser at yahoo . com

Boot into Single User Mode and remove a setup file

Restart the Mac holding down the Command+S keys, this will take you into Single User Mode and it’s Terminal interface

Youl need to check the filesystem first:

fsck -fy
Next, you must mount the root drive as writeable so that changes will save:

mount -uw /
Now, type the following command exactly, followed by the enter key:

rm /var/db/.applesetupdone

reset forgot mac password

After removing the applesetupdone file, you need to reboot, type ‘reboot’ and hit enter
