Doesn't work for me.. I open the Battle.net application, it pops up on the Dock and then just disappears. No, I did not select Case Sensitive, I chose Journaled.

Having the same problem. I tried to install Hearthstone and Battle.net client separately starting last night on my Macbook pro. They are working fine on my Windows desktop. I would like to play on my Macbook though.I have tried changing my Sharing & Permissions settings on both the Battle.net application and the Applications directory, trashing the Battle.net directory, reinstalling, looked for the agent.db in the agent directory (which I could not find, so I deleted the whole directory), and I am still having no luck! ):
