either way your right. these cards do not support all OpenGL or other features hardware (i'm unsure if hardware anti-aliasing is one of them or of a different kind). the drivers are supposed to fill in what they dont do (emulate, or HAL sometimes called), but drivers emulating OpenGL version N.M often do need to be updated to work when newly released. intel does release fixed drivers (has done so recently for linux and windows10)
you should contact apple - perhaps an update will be available soon using the normal update features
an example is the Intel Iris Pro 6200. gamers complained of glitches upon first release on Apple. however an update was released that fixed the complaints
