It seems likely but I&#x27;m still not entirely convinced.<p>I can&#x27;t entirely figure out how much the former Apple engineer quoted there was involved. He clearly knows how the SE firmware is loaded, but I&#x27;m not clear about the level of his knowledge from the SE side. The described mechanism of running a signed blob from RAM doesn&#x27;t exclude some sort of wipe-on-update mechanism, but it would have to be very low level, part of the hardwired secure boot stuff.<p>The blog post that&#x27;s quoted afterwards is total speculation and contains no information about this, even though it claims to.<p>So, probably, but still lacking a properly definitive statement.
