Dragon Age: Origins not opening on Mac OS X Yosemite

I'm having the same problem.  Just bought/installed the game. Is it a patch thing? Or does the game not support the Mac OS X Yosemite system?

I have had this problem too! I just bought the game for my Mac and everything went smoothly until I actually tried to play the game. The game launches, but the new window doesnt open, or isnt viewable. Hopefully we can find a fix for this!

I was having the same problem on my 15" Macbook Pro/Retina.  Work around was to find the DragonAge.ini file located in Document/Bioware/Dragon Age/Setting folder.  Open in up with Text edit.  Almost towards the end of the document is a section called Video Options.  I changed resolution width = 1440 and height = 900.  Make sure you save file.  Start dragon age to check and see if it works.  Hope this may help.

After some research here are settings for 13" Screens1280x800 

Thanks so much!  Worked a treat rtrfamjr2

This worked perfectly for me too! I have the 13-inch MacBook Pro with Retina display and so far, the game is running without issue!! Thanks for the fix 🙂
