The Mac Version of the PTR client is not working quite yet. We hope to have it working in the near future, but I do not have an ETA at this time.
Character Copy is currently down on the PTR. Like the WoD Beta, we'll be using the new in-game character copy option. The button is already present but copies are currently disabled.
There is currently a known crash that occurs when changing to/from Windowed Mode while in game, or changing the Resolution in-game. We're working to fix that, although it may require a new build.
