Macintosh Mac resolution issue

Hi,
Decided to come back after a little break and now I am not able to play full screen mode, only 800x600. Previously I have been able to play fullscreen after fiddeling abit with the wine settings but now nothing works. I believe I have tried everything in the Mac guide but with no success.
What happens is I am able to start the game with the default 800x600, with black bars when full screen. However anytime I try to change to fullscreen one of the following happens: The game wont start, The game will start but nothing happens only a white screen appears, the game starts and shuts down immediatly.
I have also tried editing the legends.ini with textedit, chaning the HD resolustion but nothing works there except the 800x600.
As I said I have played here before with no issues using fullscreen mode.

Thanks in advance
//Alex

 

Just noticed I am not able to resresh the wrapper, it's just loading until it does not respond.
Any ideas?
