MDM locked M1 Macbook Pro 2021 doesn`t allow to enter PIN

Hi, my organization use MDM by Miradore.

in terms of the war in Ukraine, we locked in February some laptops to save data.

After three months my colleague come back home, got her laptop and tried to enter the PIN.

I don`t know how many attempts she did but now I see that Mac is fully locked and proposes to try again in too many minutes? it`s about 24215922 minutes (unbelievable)

I tried to reset SMC and NVRAM, and start it in Recovery mode but nothing. Always I get the same error

Could someone help me with that? I have PIN but can`t enter it )))

You will need to contact Apple for assistance in removing the lock. We had an AASP remove the lock like this for us several times, but you will need the proper proof of ownership and ID for Apple to remove the lock since this is a security feature. Only Apple or an AASP will be able to tell you what is acceptable for proof of ownership and ID.

You needed to use the Apple USB-C charging cable and not a USB-C Thunderbolt/USB3 cable which has the lightning bolt on the connector. Apple makes this very confusing even though it is in their documentation for "Restoring" a USB-C Mac with Apple Configurator 2.


It is very hard supporting people remotely since the tech is unable to notice the subtle behaviors which may provide clues. Sometimes even having the computer in hand is not all that easy either.


Glad you were able to sort it out in the end.
