FPS bug still affecting Mac users in 6.7?

So we all know that there was a sound bug affecting Mac users in 6.6 that made the in game sounds fuzzy and also made FPS drop dramatically, and apparently this bug is back in 6.7. The game sounds usually don't buzz out on me, but sometimes they still do. And what's worse is that the FPS hasn't changed a bit. Fortunately the disable sounds option has been my saving grace, but having to play in silence is no fun. Is riot still looking into this?
