EFI BIOS of Imac Pro leaked some time ago

A bit old news, but
With some of DP for high sierra Apple has accidentially released fw for imac pro.
You can find it here –

Why I think it’s imac pro ? dsdt has name of model – imac. ALso there is uefi driver for amd radeon vg10.

That matches imac pro.

few other interesting things I’ve found: apple secure boot and microsoft secure boot support. first time spi flash rom is 16 mb (prevuously it waws 8 mb). voice over uefi driver (siri on separate cpu will work even in uefi ?)

    I have tried to register using two different email addresses none work.

    Having looked at the sticky notice which says to email you if you have not received the activation link after three days. I left it a week and have still yet to receive an activation link.
    I cannot see anywhere where there is an email address to write to.
    So I am writing here in the vague hope you see my request for an activation email please.
