        We can read user info one year ago. Machine User name. User Icloud. Wifi user ever connected . and wifi pass hash codes. last user location and much more info. NVRAM contains marker activated macbook or not.
        minacriss know how patch nvram to make MAC activate. but we dont know. mina and tha same tool hadly obfuscated and protected for reverse ingeneering. So the algorithm is hard to open.

        with MacEFIUtil we can capture T2 NVRAM with no problem and extract prev user name previous icloud and many inteteresting.
        but what change to make MAC activate in NVRAM - its a big question.

        If anyone from forum can reverse code of minatool.?????

          "with MacEFIUtil we can capture T2 NVRAM with no problem and extract prev user name previous icloud and many inteteresting."

          Can you explain step by step us how you get T2 NVRAM dump with MacEFIUtil ?

          Thanks

I currently do not use Mina because they are using checkrains source code to crack this which I think it's fine however, I personally am waiting for one source to update their code becuase it's easy to read their source code and figure out what they did. Mina however seems to get these things right but it's a collective of a lot of people working on the back end of checkrain.
              Yes, but even then sometimes, you cannot get a hold of the previous owner, or how many owners changed to clear it .

                I am going to buy it, and finally unlock my A1990.

                  The forums rules won't allow anyone to post links to sites that provide that service. You'll have to google it yourself.

                    How was this done, does anyone know?

                    Is this by desoldering the chip that holds that data and reading the data from it or is it some other way?

                    Much appreciated.

                      I think there is not need to desolder just jailbreak target t2 MacBook and extract info ssh commands with another Mac ,tunneling usb.

                      here an interesting paper where is explained how to user MacEFIUtil commmand

                      https://duo.com/labs/research/secure...-era-of-the-t2

                      maybe someone who already know how to do this can help us?

                            Yes, i got contacted from the Mod team.
                            I didn't think that it would be prohibited, because around Google it has a LOT of shaddy websites.
                            That's why i asked, because we are community , and someone that knows for sure that a website is working and is legit, that would be good for the rest of us.
                            That's why ,nothing more nothing less

                            So i will try to find out my way out, because it's been months since i fixxed this Apple and i have it in my bookself without using it ,and it's a shame that i repaired it

                                  Any site charging to remove your lock on your own device you legally own is absurd. That is why myself and a few others are trying to figure out the code they are using to crack into the device so we can unlock them (bypass or removal etc). I think its decent to know we now can get back into these devices however I do not support paying these websites for that purpose because its bullshit in my opinion, however I do believe you should charge people for this service if you are a repair shop that is doing the physical labor and time, but the software should always be free when it comes to this type of stuff. Then again I am biased about it because I personally provided a solution to this issue without paying these companies and had that thread removed because of the bullshit harassment I received, but you wait when we do have one of these softwares our self and watch the salt flow

                                      What he's saying is: He does not support people charging money for bypass/unlock Software and that he is working with some people to provide this software solution for free.

                                            Apple A1990 / Board number: 820-01041
                                            by RWS93
                                            Brand: Apple
                                            Model: A1990
                                            Board number: 820-01041


                                            Problem: I am not an Apple kind of guy to start with. But I am quite experienced with motherboard repairs in general. So the laptop is stuck with 5v 0.250A and does not negotiate 20v. Same symptom on all 4 USB C ports. When charger is plugged the amps start at around 0.060 then go trough: 0.100 - 0.180 - 0.230 - 0.244 and stay like this. Laptop responds to the power button: once I hold it long enough current goes down to 0.060A and then up to previous levels.

                                            Board clean, no liquid damage, no corrosion....

                                            I have changes the keyboard and the touch id. on 14 inch Apple M1 A2442,
                                            "option stuck "

                                            It did not help because the lady was playing intensive games on the laptop : The issue with the Option (Alt) key is related to the Mac’s HID system (Human Interface Device), which manages how macOS receives input from the internal keyboard.

                                            The Option key is not physically stuck. Due to intensive use of the Option key during gaming, the internal keyboard sometimes sends an incomplete input signal, causing macOS to think the Option key is still being pressed....

                                            Hello.
                                            Have this two Apple A1990 EMC3215 that starting to 5W and power off. Byt Thermocam i see that T2 ic is heating little too much right when consumption start to raise.
                                            I dont find any short in coils for it and it looks like there are voltages

                                            Any hint or bad T2 is common on this boards?
