FOR EVERYONE STUCK AT 27%:
If you go to FAQ on the website, it says the following:
I'm using a MAC computer and when I start the game, the download stops at 27%, what can I do?
That's because you either execute the game from the DMG file or you don't have writing permissions where you installed the game. You have to uninstall it and follow the installation procedure described just above.
HERE IS THE SAID PROCEDURE, AGAIN FROM THE FAQ PAGE:
How do I install the game on a MAC computer?
to install the game on MAC, you have to:
1. if you already have the game installed on your computer, uninstall it and clear your browser cache.
2. download the game installer from the website
3. open the dmg file
4. drag and drop the .app file to the Applications shortcut
5. go to the Applications directory
6. execute the launcher's game
The launcher will automatically check and update the game if necessary.
When the update is over, click the PLAY button to play!
