Forgotten password for Mac
Hello! I have a problem with my MacBook. I forgot my password, the Apple ID and the password for the Apple ID, everything. Can I do something and how?

You needed to provide your Apple ID credentials when logging into this site. That means you used a different Apple ID when setting up that Mac. If you literally have no idea what that Apple ID was then you need to initiate an Apple ID Recovery request.

You have a significant amount of work ahead of you since your Apple ID = You as far as Apple is concerned. They are one and the same and indistinguishable from one another. Recovering an Apple ID that you forgot is analogous to attempting to assume someone else's identity.
