          Does it have EFI Password or Activation Lock?
          Activation Lock is the same as iCloud Lock on iPhones. Not sure if you could get around that.

                  macOS Catalina allows you to block the firmware from showing the seed that Apple needs in order to remove the password. Type this in Terminal: sudo firmwarepasswd -disable-reset-capability.

                        Hey Siddig, BTW, do not try unlocking it via the image. I unlocked mine using another mac. just link them both and then you can unlock them. now the reason I want to dump the image is because I want to modify it.

                              EFI is stored on the encrypted NAND chips and fed to the PCH by the T2.

                                wrong wrong wrong! the 4mb bin its only thing you can do is change serial no unlock!
                                4mb bin you can read and manage with neo, if you have a good macbook and copy efi free bin to the same locked macbook dont work, also read locked mac and after unlock read again and compare and change is not working! activation lock is not only linked in serial!

                                ps the chip is a wson 2x3 1,8 volt

                                    Have you guys considered hijacking the iCloud dns and pointing it to a local server that is emulating the correct response to report that it is not locked just long enough to unlock it to disable secure boot?

                                          by mferna14
                                          Hi friends., I am working on MacBook Pro A2159 touchbar 2019. The old logic board was liquid spilled so I ordered another logic board from AE. Received it & all worked fine till I got to the Chinese login screen where the login screen password tobe entered. I tried to reset the password but it again gave me options which I do not know about the Apple ID. I formatted the onboard SSD. & wanted to change the startup boot sequence but in order to change it, again the password is needed for that too. Is there a way to get rid of this password?? The seller has not replied back past 2 days, how...

                                          MacBook Air 13 2014 - Remove EFI password
                                          by ritalo
                                          Hello,

                                          I have a MacBook Air 13 inches 2014.

                                          I have set a EFI password and I can't remember it : now I want to reinstall macOS and I can't because the MacBook is asking for the password.

                                          I know how to remove the password with a usb programmer.
                                          I plug the usb programmer to the motherboard and to my pc with usb, I read the EFI and I save it to a file.

                                          Then I have to find this value in the file : $SVS because it indicate where is the password.

                                          But I can't find the value.

                                          I have attached the file​

                                          Thank...

                                          I have done many of these over several years, But its been some time since the last time.

                                          Normally I dump the rom 3-5 times and compare before anything else
                                          Which I do have clean dumps, then I would search for $SVS and ff ff out every thing that follows that including the $SVS all the way down to the next large series of ff ff

                                          Upon 1st boot I will zap pram a few times, Password IS GONE
                                          yet the laptop is acting strange, powers off all of a sudden for no apparent reason.
                                          Besides that, the trackpad clicker does not work in internet recovery and other odd...

                                          MacBook Pro 2018 with Activation Lock

                                          Hi everyone!

                                          I have a 2018 MacBook Pro (with Sequoia OS) that I've been using for years with no problem. I recently received an M2 MacBook Pro so I'm mostly using it and not the 2018 one, but since a friend of mine needs a computer, I thought I could restore my 2018 and give it brand-new-like to my friend.

                                          I tried using the built-in tool to restore the MacBook (Settings > General > Transfer or restore > Delete) but it got stuck when trying to remove the Find Device configuration (it asked me for the password for my old Apple ID -now I use the same account but...

                                          MacBook Pro 2018 - A1990 Dead - not charging - only 5V

                                          Hi,

                                          my MacBook Pro 15" 2018 Touch Bar (A1990) doesn't charge anymore. Board# 820-01041-A

                                          I'm not experienced in diagnostics, but I want to try to solve the problem with your help, because every local shop charges around 600€ (650 usd). Which is the value of the whole Macbook.

                                          The Macbook was charging when suddenly the "charging sound" appeared every other second for around 4-5 times.
                                          After that the Macbook was dead. It isn't charging anymore.

                                          The USB-C Port where the charger was plugged is burned. Also The Cable and the...
