4.13 VR Blueprint only for Windows?

Hi, installed 4.13 (first-time use of UE) on OSX 10.11.6 and when creating a new project, there is no VR blueprint. I also cannot use VR preview in other projects (grayed out)

Is this a OSX specific problem?

The only potential hint I could find was here: Virtual Scouting | Unreal Engine 5.1 Documentation where OSX is not listed in system requirements.
