How to Wipe / Hard Reset a MacBook 2015 - with Big Sur

[DaneTheGr8]

Hey Guys,

A family member has gifted an old MacBook 2015 with Big Sur I think as the latest OS however does not remember the Computer's Login Password. I've tried troubleshooting to resolve this. This person has moved predominantly android and does not have any other Mac OS devices to access to get the password.

The email for the iCloud is no longer in use and she does not know her iCloud password or which email address even was used to wipe.

How would I be able to login or wipe the MacBook on boot to set up. Bear in mind I think - it is running Big Sur.

Rebooting in Recovery mode does not work as we are stuck on the password needed to continue.

Without the iCloud login, your only hope is to take it to Apple with proof of purchase. I believe an original sales receipt will suffice. If you don't have that, the machine is worthless.
