HASH FOR EFI was created by SomeGuy
When you get the hash code how would you go about using it to create a file to then unlock or bypass efi without going back and reading and writing the efi chip. For example I have seen you can send certain people the hash code they then go back and send you a file which lets you sign into mac and then no efi and its like it starts it all over fresh to brand new setup screen.

as far as i know, that service is done by apple. anybody offering that service likely has access to GSX or the like.

Yes I'm sure. I speculate he is working with somebody at Apple. I'm sure if how to decrypt the hash was leaked, it would be over now and everybody would know.
I could be wrong though.

I don't think he decrypts it. I believe somehow he puts it into a file like a clean dump with a serial number because he ask for both" hash & serial "he said that he does something similar but doesn't explain he then sends you a usb flash drive and you plug it in then it starts right up showing the brand new setup for apple. I am thinking about paying him for 1 just so ill have the file to reverse engineer it

Somebody was kind enough to provide us with a signed .SCBO but i didn't have time to check it out.
It's probably worth having a look at indeed.

Sounds like a good idea that would make things so much easier to bypassing efi pw's to be able to just use the hash and serial and create a file

yes well... the .SCBO is only 324 bytes.
it contains the hash, but i don't see the serial used anywhere.
there's not a whole lot to go off of here lol

I know the guy who does it ask for both serial and hash and then says he will create the scbo file and you then just plug It in and it bypasses the firmware lock.

Well I'm unable to say how that scbo is created.
I'd be interested to see what happens simply replacing the hash in the file.
Perhaps the remainder of the file is generated per the serial, but how it's done is unknown to me

I wonder how by changing the file and booting to it that it is able to access the efi location to bypass. I was also told when you do it that it lets you reset it like a brand new mac like you don't have to go in and clean hd and stuff you just pop in flash drive then boot to it then it says setup your new mac etc...

Well, all hearsay aside...
How much does that service cost?
Apple has clearly built in some backdoor access, but as far as I know, that scbo has to be generated by gsx.
I would need a control... to lock a mac of my own and then have the corresponding scbo to compare against this random one... and even then who knows what we may or may not find.
It could be next to impossible if the remaining portion of that file (after the hash) is generated by some algorithm using the hash and the serial

shoot. the average MacBook takes me <5min to unlock with the equipment i have on hand.
paying $160 for the convenience of not having to open the case is not for me lol
