Currently there have not been any announcements about other platforms.
Unfortunately, Parallels
does not have hardware support for DiretcX 11, so you would need to use Bootcamp to run Windows to be able to play the game.
Integrated graphics are not officially supported, but Iris GPUs do have hardware support for DirectX 11. In terms of performance, the best Iris models slightly exceed the minimum requirement, and the lower end (included on the PassMark benchmark list) are half or a third (so might run with usable performance at a low resolution and graphics settings).
