Macbook Pro (late 2016) egpu passthrough

[AlecB]

Hi all.

The new Macbook Pro 15" comes with 4x thunderbolt 3 connectors. That gives each of these ports 4x pcie 3.0 lanes. Will parallels allow for egpu passthrough to a guest? I was thinking steam running on a Windows 10 guest. Wanted to confirm this setup before I got myself an egpu chassis.

Thanks!

Did some digging, Apple has supported vt-d on OS X since 10.8 (mountain lion). So anyone saying there's no support for it in OS X is just wrong, it's a requirement for thunderbolt to even work period and be secured. All thunderbolt devices get managed with vt-d virtual addressing on OS X to prevent DMA attacks.
