Good luck.

Pro Tools does NOT use Metal. There's a big misconception that since the introduction of Metal in El Capitan, every app somehow "has to" to be using Metal to work under El Capitan/Sierra/HS -
not at all. Metal is actually used mostly in games, but for a vast majority of apps out there, including Pro Tools, Metal is almost irrelevant. That's about to change with Mojave though, but that's because Apple chooses so. I bet PT 2018.x will still work under 10.14, and will still not be using Metal in any way shape or form. As frustrating as it may be for Apple, Open GL still has to be part of the OS. And as Jack said above, the stock GPU in the 2010/2012 Mac Pros doesn't support Metal, yet PT runs perfectly fine on these machines, not to mention El Cap, Sierra and HS by the way.
