MoltenVK is a driver for Vulkan on macOS and iOS. It will work with any Vulkan development kit or engine that links to it. However, it is up to the development kit or engine to use the extension required to support any given platform (e.g.- Windows, macOS, etc).
GLFW is open-source. We recommend that you post a request to the GLFW development community to support macOS on Vulkan by making use of a library such as MoltenVK. We will do the same, and we’ll see if we can get the ball rolling.
