 3. You must download [makeMTGArena.command](https://raw.githubusercontent.com/abcbarryn/MTGArena-for-mac/master/makeMTGArena.command) and run it. It will create MTGArena.app, which is a custom Wineskin wrapper you can use to install MTGArena.

If Wineskin ever gets around to updating, you can get the official download [here](http://wineskin.urgesoftware.com/tiki-index.php?page=Downloads).*
