Just opinion but i will be not surprised if it's apple fault. I remember when apple dropped support for OpenGL, and arenanet make announcement that macos client support will be dropped because of this. What was funny in this story is, people blamed anet, not apple - which is irrational. Before you blame someone, think twice. Also, releasing software on mac is pain and their requirements are pure joke. Chill.
We don't know full story so i encourage empathy and patience. Some things may be out of their control.
