My rant aside, does anyone have any insight on a method to get around this restriction? For what they charge for hardware, I should be able to do whatever I want to this machine. I know Apple is "Big Brother-ish", but this obnoxious. I also really don't like the idea that I've purchased hardware which doesn't allow me to install the software I actually want. I'm not willing to put High Sierra on my network yet, it doesn't play nice with profile management or Munki. I imagine it's just a piece of information somewhere with a version check, if I could find that file maybe I could lower the minimum version? I wish I knew how Apple was able to perform this restriction. I'm now thinking of trying to clone the hard drive from the other MBP I have that's running Sierra onto the new one. I've tried to sidestep it a few ways, none of which have worked. Is there any way to force this laptop to boot into a bootable Sierra install USB drive so I can perform the downgrade? I can't even get this laptop to boot from a live Linux USB, I just get a giant "No" icon. The explanation I found is that the drivers don't exist, but I know for a fact that the drivers exist since there is another MBP at my company shipped just a few months prior with the same specs, running Sierra. I'd like to downgrade to Sierra but am running into the issue that you can't install a version of the OS lower than what was shipped. New MBP purchase shipped with High Sierra.
