You know the Shift + Option + Command keys & whilst holding them down, depress the letter R (and I’m sure you know all this already but just in case….👍

Are you getting back to me pal you need to DM me as it’s a little complicated and it will be easier messaging each other that way but alas don’t worry as long as it’s YOUR machine you will not have a problem you will be back up and running in 15 minutes 👍

Oh just incidentally you say you have tried all the recovery steps but did you actually manage to get into the recovery page/mode? I know you said it didn’t work but did you manage to get onto that actual page pal….?

Do you need help still pal or have you rectified your situation, if you do still need help message me and I’ll explain to you how to get yourself back into your machine ok my friend regards Byron
