    Pre 2011 Apple Mac Firmware Password Removal

    1.) DUMP EFI ROM from a EFI Locked mac (PRE 2011 Models) using a BIOS programmer
    2.) Search the below HEX inside the Rom using a Hex Editor (Try HxD) :

    730065006300750072006900740079002D00700061007300730077006F0072006400

    3.) Copy the Hex Between "00 00" "AA 55 7F" or "AA 55 7D" from the HEX Editor
    4.) Go to http://halflight.com.au/wp-content/u...8/macHash.html
    5.) Paste the copied HEX code in to the Hash input field with % instead of spaces between HEX and click Decode. You'll have your password decoded. Enjoy!

    started a topic Firmware password on A1286 820-2850 A EMC2353

    Firmware password on A1286 820-2850 A EMC2353

    Hi Everyone,

    Can someone please explain how can I remove firmware password from Mac-book A1286 820-2850 A EMC2353 i5 2.53ghz .

    Do I need to flash the new dump? or I can remove the password from old dump using some method?
    If I use the dump from ghostly hacks and replace the serial number would it work fine?


    Thanks in advance
