Unlock Bios Password iMac 27 19,1 a2115 Firmware Password Unlock.

[JohnnyHotPockets]

Hi Guys,

I need a firmware password removed from my iMac that I bought 2nd hand. I've searched as far as I can and found this website, excuse my ignorance but I'm not sure how it works. How do I find the BIN file to supply to request unlocking? Once I have it, how do I apply the new one? If there is a link to a tutorial or something to assist I'd love to know. I found this post here: Unlock Bios Password - IMAC A2115 which is the same iMac I have, but I wasn't sure, is there unique identifiers per firmware or can I use the unlocked file from this one? If I can use this one, how do I use it. My apologies for the questions, but I'm at a loss.

My details are below:

Motherboard number: 820-01236-A
Family name: A2115
Production week : 26 (July)

I've mounted the EFI partition, but I'm not sure if what I need is in there or if it is, where to find it.



Any assistance would be very much appreciated.

Johnny

Again, thank you for your patience, I found this and extracted it, is this it?

yes it is
but this file does not have bios password on it

 

[JohnnyHotPockets]

Hmm.. OK what about this one?

 

[Vahab Hemmati]

Hmm.. OK what about this one?

this one too
there is no password on file

 

[JohnnyHotPockets]

Hmm.. maybe I'm doing it wrong. So when I boot to recovery, I get the firmware password screen. Those two files were extracted from refi > APPLE > FIRMWARE > IM191.fd on disk /dev/disk0 and /dev disk1

maybe need to try new bios

Bios - iMac Retina 5K 820-01236-A Bios

iMac Retina 5K 2019 820-01236-A Bios

If I replace the IM191.fd with the BIOS file from here Unlock Bios Password - IMAC A2115 will that reflash it?

yes its possible
give it a try

 

[JohnnyHotPockets]

yes its possible

Just so I'm sure, and again, I appreciate your patience and assistance, like you have no idea. If I do it, I call the replacement file the same name (rename it to IM191.fd)

If it doesn't work, is there a chance it will brick my iMac?

the only way to unlock bios password is removing it from bios bin file
but the files you have sent are clean! and there was no password on the file

I'm at a loss haha. I thank you for your assistance, I might just try to replace the file with that unlocked from the other thread and see what happens as it definitely has a firmware lock on it.

Thank you for your assistance though. I very much so appreciate your help. If I can find something else ill post it here.

I would but again, no where that I can find explains how to flash Mac with a new BIOS.. unless I'm a dumbass, I can't find how to. I been looking for a few hours now. For example, where to put a bin file. or how to flash using a BIOS bin file on Mac. I can't access anything outside of live OS because of the fw lock.

unfortunately the schematic is also unavailable for this board
it would be helpful

 

[JohnnyHotPockets]

Yeah, thanks man, but it's midnight here and I'm kinda over it for now. Ill look more tomorrow.

Appreciate the help
