Accepted as values for the EGL_PLATFORM_ANGLE_TYPE_ANGLE attribute:

None.
New Behavior
To request a display that is backed by a Metal driver, the value of
EGL_PLATFORM_ANGLE_TYPE_ANGLE should be

RESOLVED: No, use the default returned by the system. It doesn't
seem like recommended practice to choose a Metal version when
initializing a Metal device.
