Morning everyone! This query isn't for me, but for my friend located in Australia. Twice now he has tried to use Bootcamp on his Mac. Twice now he's got into a situation where Bootcamp won't even load. He has the same Mac book as me, early 2015. Please does anyone know of a way where the Mac can be completely re-installed with everything wiped? See from Mojave, it appears that Apple have changed the install procedure, so it wont reset everything. He has tried Command plus R and used the re-install option. This won't do anything and his Mac is exactly the same as before, with a Windows operating system that's unbootable. He has heard somewhere about another key combination, command plus R plus P then powering the Mac up. Is this worth a shot? Please any help would be appreciated, as both me and my friend are at a loss as what to do next. And to top it all off, it says in Disk utility bootcamp locked. And he can't even use that app to remove it. Whenever he launches it, and clicks continue, it's coming up with the following message. I can't remember the exact wording, but it's something like this. The disk cannot be restored to a single partition. The startup disk needs to be formatted as Mac Os Extended Journaled. Like I say that's not the exact wording, but it's something to that affect. Please any help would be welcomed. Thanks very much, I look forward to hopefully some responses. Gary Price Sent from my 13 inch Mac book pro.
