I've bored you enough with the story, let's get to the exciting part. I'll describe the method that worked for me; it may be somewhat different on your particular MacBook. I am also not responsible for any bricked Macs this may result in, do this at your own risk with the possibility of a bricked Mac in mind. First, we'll need to verify that we can interface with the EFI flash chip at all. To get to the chip, you'll need to disassemble your MacBook to the point where you can see the top side of the logic board and identify the chip.

On the A, the chip is located near the SD card reader and speaker. The chip will be fairly large and have eight pins. The particular chip on my A was a Micron 25QA. To use it as an SPI programmer, we'll need to install flashrom from the Raspbian repositories. As far as I know, the pinout should be identical for all Mac EFI flash chips, but be sure to check the specific datasheet for your chip and modify the wiring as needed.

This will load the kernel module we need to do SPI programming on the Pi. I was initially worried about the fact that my exact chip wasn't on the flashrom supported devices list , but it turns out that the N25Q You'll probably want to make more than one read of the chip, just in case anything was corrupted. We can check that the reads are identical by checking the md5 checksum of the files. Since the checksums are identical, we know that the files are identical too. As an extra precaution, I made two more reads and copied the files to another computer.

This string denotes the blocks of hex values with the firmware password. To get rid of these blocks, we just need to fill in the hex values with "FF" without quotes. Once we're done, we can copy the modified file back to the Pi. I once again copied multiple times and checked the MD5 checksums, just in case.

And, with our modified file mod. Once the process completes, you can turn off the Raspberry Pi and put the MacBook back together. If you've done everything correctly, the MacBook should just power right up. The firmware password may appear upon initial boot up, but don't worry! This will clear the firmware password from memory, and you should now have no firmware password. Nice and detailed instructions but in my case i did some command line modification for get this work complete. Before read a bin file from chip i did connection test using below command.

To read to a file read. For erase the chip on the logic board i used below command line. And the final part of writing the modified bin file below the command line worked for me. Sorry, something went wrong. However, I encountered a small problem during the process. I couldn't find any solution. I finally, as an act of desperation, just tried to read and then write to the chip using vijaykumarta 's commands.

And it just worked! Skip to content. Sign in Sign up. Instantly share code, notes, and snippets. Last active Mar 7, Code Revisions 8 Stars 25 Forks 6. Embed What would you like to do?

You may be able to reset, change, or disable the firmware password using the same method you used to set the password to begin with, this requires booting into Recovery Mode:. Always check your caps key and num lock key before entering or modifying passwords, often mistakes are as simple as that.

Because sometimes it works, maybe because of user error when typing the password to begin with. Yes you should actually try it. This works on modern Macs, including the following this list is not necessarily conclusive, always contact Apple directly if you can not remember your firmware password regardless of the Mac :. You can contact the official Apple Support channels by phone , or schedule an appointment with a Genius Bar at a local Apple Store.

Again, even if your Mac is not on that list, you should contact them. In most cases, you will need to provide proof of ownership of the Mac which has a locked firmware password in order for them to unlock the computer in question. There may be exceptions for a variety of unusual circumstances, discuss those with them if necessary. They can probably still help you to unlock the Macs firmware login. That is a fairly technical process, which makes it appropriate for advanced users and systems administrators, but it should not be attempted by a person with novice computer experience.

Have another solution to unlock a Mac with a long forgotten firmware password? Let us know in the comments. Get more of our great Apple tips, tricks, and important news delivered to your inbox with the OSXDaily newsletter. Apple would not help! I fixed it by putting one of my passwords for my other Apples on my networks in. Would I have to delete my iCloud account? In my texts back-and-forth with Apple I have screenshots of find my with the Mac still there before they asked me to follow their directions and remove it.

If I can upload the screenshots I will show you. You will be given an unlock code, and the firmware password will be replaced with that code. I am in much the same situation as I forgot my find my passcode and now if I boot up with command or it goes straight to the firmware password lock screen. I am a cancer patient that has been prescribed pain drugs for a considerable amount of time so my memory is not what it used to be.

If any of you start a lawsuit please, please contact me. I am in close to the same situation as much of you. I forgot my Find My password on my mbp. I just plugged it into a cat six ethernet hardline one day and it locked! If I reboot and hold down command are instead of going to safe mode it comes up with the firmware Lock Screen!

I have had marketplace send emails to the seller with no response. I have tried to get a hold of the seller with no response but I bought it in and the gentleman was 65 then so I fear the worst. I am feeling very discriminated against by Apple As I said and if any of you start a lawsuit please, please include me!

Apple needs to pay!!! No option to enter password. Question mark folder with most key combinations. White screen when hold command with mous cursor. A flashing question mark folder usually means the boot drive or boot OS can not be found, try booting from a boot disk. This just means that your device has no drive to boot from.

U need to boot from utilities and then reinstall the os and then the problem will be fixed. Hi Hina, at least you were able to formatted yours. And I still cannot format my Mac late I have a macbook pro, and i forgot the firmware password. I never expect something like this will happened lol. I just locked out of my macbook last year and now I just keep it without using it because my mum bought it for me and it means a lot to me.

Think about it. You think apple would assist in bypassing the firmware login screen? Dumb question, I know, but its not your fault someone else committed a crime. The original owner of the computer should have a gripe with the person who stole it, wouldnt you say? Yes, I just tried it and it worked great! My MBP was working fine. All good until, I tried rebooting back to macOS — Mojave v However, I can only read any directory or files, since the mac volume is encryption.

I just cannot boot into macOS. Only using the Boot Camp volume. How can I correct this without having to hunt down my purchase document, and then having to send this mac out to an Apple depot?? Use that and put it on a USB and tell apple to unlock it, because the unlock seed is a valid password. Thanks for the tricks. So another trick is : translate your password in qwerty mode! So I locked my Mac after someone at my home was stealing info from it while I was out of the state.

In doing that it locked my firmware too. I have tried multiple times to unlock but nothing has worked. At one point I did upgrade memory for my Mac, would make me a difference? Please help! Hi, the firmware password was activated without me knowing it at all. I have got to visit Apple in central London to fix it and still under warranty. Has anyone been able to sort this out? Unfortunately been a victim of a crook and bought myself a second hand locked MBP.

One of these days they should be sued honestly as this is BS. The iPad stolen from me never made it back home so what kind of security is that. The laptop will likely be confiscated. I am the original owner and am getting ready to sell a mid mbp. Backed up all my stuff, did the Cmd-R boot and set install a new version of he OS.

It worked well and created a new home directory and all that. But there was still gigabytes if used data in the machine. I went into the Cmd-R reboot again and accessed the disk utility and erased the drive. While setting up he new machine, went into find my device and selected the old machine and selected erase. It asked me to enter my iCloud password, which I did. Then it asked me to enter a six digit password to stop the erase on the old machine if I wanted to.

I entered a six digit number thankfully easy to remember, and was expecting the old machine to format itself any moment as both were powered on and connected to the internet. Nothing happened for a while. I out the old machine away for a few hours and played around on the new machine. I did the install OS command and it downloaded the OS from the internet and rebooted. Then it presented me with the firmware lock, which I had never set. I entered the admin password I had used.

No luck. I entered my iCloud password. Then I thought about it and entered It unlocked the firmware password. So, for those of you locked it, log into iCloud on a different machine. If the old machine is still listed in your list of devices, erase the machine. It will ask you to enter a code. Then try that for your firmware password. On and older macbooks the RAM trick works just fine.

But and newer requires either having a utility to rewrite the efi chip, have apple unlock it, or replace the efi chip with another programmed one. I always replace the chips and it works great. Boot up your Apple computer while holding the option key. You will get the screen wanting the firmware passcode. You will get a one time hash code. Call and tell them you have the has code and they will email You a file to put on a FAT formatted flash drive.

Turn you computer off boot with the flash drive in while holding the option key and that should do it. Apple may require proof of purchase to do this. Hi I am in the same situation as most of the people above. I bought an iMac 2nd hand and the previous owner had installed Windows 10 as the operating system. I wanted to reset it and install OS X so I thought it was a good idea to format the drive so I can do a clean install.

I confess I saw the warning on file vault but since I knew I was formatting it I went ahead and formatted the drive. Now I am learning about the firmware lock the hard way around. If anyone finds a solution please post. David at Rabya dot biz. Got a all in one apple computer.

I got it at Best Buy 5 years ago. I turn it on and I am getting a flashing? I never set up a password of any kind on this computer. And I have not got the receipt any more. If any one can help please e-mail me. And why was I ever apprehensive about registering a new apple device and fearing foregoing privacy with each new device. Am I getting close to solving one of apples problems? Cause my invoice is already in the mail.

Very suspicious as my mac air locked itself down to the firmware password screen during normal operations. All the sudden the mac air basically crashed as it appeared then emerged a black screen with multiple languages hovering over the firmware padlock icon??? Have no idea how or why it happened… thAnk you all for sharing your insight and experience- learned a good amount While locked out.

How is that possible? I am asking seriously, not ironically. Device costs a LOT. Very important to remember. With PC you get unlimited tries, you just have to reboot after 3 wrong tries. Bought my macbook pro on ebay.. Took it to an apple store, and same thing happened to me. They told me they want proof of pucrchase such as the original owners reciept. My cousin try to unlock it but couldnt… all he ran into was this proplem. Can some one help me???? I have a macbook air and bought when the owner did not know it had set the firmware password, but was set up and it turned out that he had no way to get it.

I need to get it back. You can try rebooting the Mac into Safe Mode hold down Shift key on boot and see if that helps, if so it may be a kernel extension or system plugin that is causing the problem. The Console app can sometimes help to locate the problematic issue, find the kernel panic in the Console log and look for what was running immediately before it, it can sometimes be telling.

Rarely, it could be a hardware issue causing the kernel panic, like a component or some other accessory. My Macbook Pro is locked by a theif using the findmyiphone in my stolen IPHONE 6, I already showed to apple my receipt and my box but they cant allow my mac to be reformatted because the serial number is not indicated in the receipt not my problem anymore because the store forgot to include it.

Already Contacted apple security but they are very strict. The apple ID in the mac is registered under my name matches my ID but they never considered. I hate how they misjudge and dont help their loyal customer. I will not buy apple device again if they cant help the true owner of the device. I already brought it to the apple service center and paid a hundred dollar just to reformat it not under warranty anymore but it was not refundable and still my mac is locked because apple does not honor my receipt.

Please teach me how to reformat it my self contact me using my email. Thank you. How are you ment too.. Paul…why so condescending? There are many honest ppl trying to purchase expensive products secondhand. To think everyone is stealing is more of a reflection of yourself…. Apple has the mind power to create a tracking system based on serial numbers.

Register the device time of purchase. And upload that info into a database available for later. If a device has been stolen, they customer calls in. The device is locked simple. If there is no report of the de ice being stolen then apple should be able to assist. Customer service is another part of sales ppl tend to over look.

Hmmmm if you go to buy a MBP you should probably learn to check to make sure they clean and rest the computer so that its a clean slate for you before you buy it and that includes the EFI.. Duh and if your going to set a password using a different keyboard.. Your fault duh think… Ahead.. Use some common sense.. Need make sure things are clean. To set a EFI password, the system accepted Turkish characters.. Is it my fault??? Did any message apeared to say this to me before I set the pasword??

Of course, not…. I now have a dead machine that costed me USD.. Apple is not a friendly company…And that was the last apple product I buy.. PS: I have lost proof , or documents they give me when I bought it.. Word on the street is that they need the original receipt because there are password bits in the original transaction numbers or something. I am still skeptical. Users can unlock the firmware password as described above, but Apple wants the original receipt because they want proof of ownership, they are not going to unlock the firmware password for a stolen Mac, for example.

The Firmware Lock is hurting second hand buyers more than hurting thieves. Even if they did contact me to help them out… what a burden. Am I really going to want meet up with them at an Apple Store to verify the situation? Hell, charge me, fingerprint me, background check me, make me wait a grace period. Find a solution for this Apple to protect your customers.

A solution to this second hand sale glitch helps the seller and the buyer buy more Apple products. This is very true!! And appl eis only going to say: Sorry!! Yesterday i saw a movie in my macbook. Today I cant login my macbook.. I tried with Apple ID password. Anything didnt work.

What can i do..? I donot know about anything of this setteings. I am new to OS system. Beat it! Hey sdpoulter, I wonder if there are enough of us to start a class action suit against Apple. I bought my Macbook Pro a year ago from a doctor who is now out of the country and hard to contact. Two days ago my housemate copied an older Mac OS from a disk onto a thumbdrive on my machine and forgot to remove the disk.

My machine evidently tried to boot from the disk and this triggered the firmware lock. Apple wants proof of ownership that I will not likely be able to provide. I feel the burden of proof is too high and that they have essentially stolen my machine. Bought my laptop secondhand from the owner off of Craigslist. Of course… my emails and texts to that individual are just past the end of my email and text chains so… I am stuck. This is a victory against theft!

So… no one wins, everybody loses. The person I purchased from I have lost contact with as well. After using for six months mine locked up. LOL Same here! Last night, Mar 12 or was it this morning mar 13, ? First and foremost is the monopoly itself. Since monopoly has set that you must produce a receipt, they could very possibly take your item as in seize it just as plausibly could the entire justus system.

We record all video and audio here for every transaction in the hopes of warding off potential miscreants. When we did the reset the firmware lock appears and we do not have the password. We were given a phone number and I contacted the person and he agreed to pay me what I had paid for it, only when we met it was not the guy I bought it from but someone else.

The guy I bought it from had bought it from this guy, who was the original owner. He said he was sorry and could not do that. I told him all he had to do was call Apple and tell them to reset the password because the case is all logged and ready for him to call. I am being held hostage by this guy.

A great post, very good to know indeed. Why pay for Apple or someone else to fix it. I like this knowledge. In all previous terminal machines this never happened. In many cases, e. So a diff. I use File Vault. I selected the option to allow Apple to store my decryption key, so if I forget my password, I can get help.

Really would. The process Apple gives to authorized service providers is a bunch of work. If I remember correctly, they send you some encrypted disk images and a terminal command that you have to use to put it onto a dedicated USB drive. The password they give you is really long, and I think it involves more terminal commands. I work for Apple and scrub Firmware daily.

Low-level passwords are quite secure, which also means there is potentially a headache if the password is forgotten. The process requires the original receipt or invoice as proof of purchase. Earlier versions of macOS required manual installation of the firmware but, starting in , Apple began bundling EFI updates with the macOS updates in order to deliver security patches to all users.

But as security firm Duo Labs discovered in late , some Macs aren't getting the right firmware , which makes them vulnerable to hackers. They recommend checking the firmware version and updating if needed. That lead to a serious security issue, allowing the firmware to be revealed in a native macOS app and weakening the enhanced security Apple had hoped to introduce with the addition of the firmware password.

In , however, Apple added an important change to the system: the firmware password was moved to a separate programmable controller from Atmel. This component contains lockable flash memory to store the password and requires special programming with identifier numbers for both the Mac's motherboard and the Atmel chip to access and reset it.

Since the controller is an independent component, the only way to bypass it is to manually remove it from the motherboard, but this requires highly precise reflow soldering tools and techniques. You can check our guide on how to upgrade the RAM on Macs for further reading. If none of the above methods worked, there are still two more options to try: either have Apple do it for you , so long as you have the original receipt or invoice, or alternatively use any of the EFI lock bypass hardware kits available for sale on various sites.
