Compiling Universal App in windows which won't run on my Mac

Hi I have compiled my application on windows using unity 2.6.1f3 to a mac universal binary. When I copy the app to my mac and try to run it nothing happens at all. I checked the Mac player log file and no errors are generated.

I checked inside the /Contents folder of the app and in the MacOS/ folder. The file in that folder which should be a unix binary file shows up as a Document instead. I suspect this has something to do with it, but am unsure how to change the type of the file or why unity is compiling it this way.

My application works perfectly when compiled for windows or the web player.

Any pointers would be appreciated

Thanks.

There seems to have been a bug in 2.6 which doesn't set the permissions for the executable inside the app

If you do

chmod 755 /PathToYourApp/Contents/MacOS/YourBuildName

from a mac, it should fix it immediately

It also seems that if you copy the app from windows to Mac then back to windows and then back to the Mac again the problem goes away. Go Figure?? but it works.
