LWJGL Vulkan on Mac OS X

I’ve been trying to run the LWJGL Vulkan “TriangleDemo” from https://github.com/LWJGL/lwjgl3-demos/blob/master/src/org/lwjgl/demo/vulkan/TriangleDemo.java but just cannot get it to.

I’m using the latest LWJGL 3.1.7 and OS X 10.10.5.

The first problem I encountered was the warning that libvulkan.1.dylib was missing, so I downloaded LunarG and scavenged it from there. Now the demo at least runs, until an error check within the demo throws this exception: Failed to find list of required Vulkan extensions
Described code: https://github.com/LWJGL/lwjgl3-demos/blob/37c20a950c2daaa4ffbea9d14bc3e5f658afc4fa/src/org/lwjgl/demo/vulkan/TriangleDemo.java#L1129

Has anybody got Vulkan running on OS X reliably and what could be a possible solution?
