I am trying ways of getting rid of firmware EFI passwords on newer macbook's. Back in the day all you had to do was change the ram configuration, do a COPR key sequence at reboot and the password was erased. Now it's not so easy. I see gadgets on ebay and new ATMEL flash chips available to solder on, much like the newer PC laptops with the dreaded bios password.
My question is, do you think a USB Jtag NT could be used to flash the chip and remove the efi password?
I saw a method posted online to use a OSX 10.5 disc and use the firmware password reset utility and I tried it and it worked on a Macbook Pro (late 2011) running OSX 10.7, but the same method will not work on my MBP pro early 2011 running mavericks. It says it was successful but when I reboot, it is not.. just bored and playing around trying to learn something here.
Anyone else care to try it?
