    MDM removal on 16 inch 2019 A2141 MBP & 15 inch 2018 MBP A1990

    Hi there,

    This is my first post. I just wanted to come here to get a clear answer from some people about MDM removal on the 16 inch 2019 A2141 MBP & 15 inch 2018 MBP A1990. I have seen a lot of things on MDM removal, and wanted to know exactly what is needed to remove it, and what the best option is in 2024 when running Sonoma.

    I know that Checkm8 have an MDM removal service now, that seems to be a permanent removal. I also have heard you can remove the T2 ROM and use a programmer to read the data and change the serial number. Im not 100 percent sure if this is a permanent solution or not? I also have the UBOS-2 tool, that I got a little while a go. I was also wondering if this is any good for removing MDM locks? Do I need to get a known good serial number from somewhere to use?

    I would really appreciate it if someone could explain the best way to remove an MDM lock permanently from these models of Mac. I have just heard multiple ways to do it, and not sure on what is best?

    Thank you so much.

    Apple MacBook Pro 16-Inch 2019 - A2141 - stuck at 5V
    by martyjelen
    Hello, I have this Macbook A2141. It stuck at 5V / 0,075A. I measured all 4 ports, all the same. PPBUS_G3H is present but only 12,3V. Should be 12,6V ? according to this article : https://repair.wiki/w/MacBook_Pro_A2...w_at_5V_repair

    PP3v3_G3H_RTC_X is present - 3,3V

    PP3v3_G3H_SOCPMU is present - 3,3V

    ​What else should I check?

    Thank you for your help.
