It does not appear to have a Metal backend - just OpenGL and Vulkan.
From what I can tell, commercial game devs treat Mac gaming as an edge case and mostly only the large engine devs care about Metal support (with exceptions, of course).

Looking at a running 1.15 Minecraft instance I see it is using lwjgl 3.2.1 and there a link to "net.java.openjdk.cmd/com.apple.metal", when I do an lsof.
Any further insight would be appreciated.
