Need help from someon

[Cityofchampions33]

I have a Mac and am having trouble downloading the league file, when i do get the league file on my desktop, and click on it, it says "there is no default application specified to open the document" and gives me the options of canceling or choosing an application. Any help in letting me know what I should do would be much appreciated.

did you download the ootp.exe file already?

Not sure, like I have the file on my desktop, just can't open it.

He has a Mac, and they don't run on it. I can't run the league and make changes. Is there anyone here who can help him out and make his lineup/manager changes?
