I know little about Macs, but this little utility was compiled for Mac/Win/Unix.

In your savegame folder, you should see a filepath: \<myleague.lg>\news\txt\players
Take that players directory and simply make a copy of it and all its files in the news/txt directory.
Get your flip utility and place it in the players folder.
Get to a command line and then run:
flip -m *.* (if Mac uses syntax similar to Windows)
Code:
Usage: flip [-t|-u|-d|-m] filename[s]
Converts ASCII files between Unix, MS-DOS/Windows, or Macintosh newline formats
Options:
-u = convert file(s) to Unix newline format (newline)
-d = convert file(s) to MS-DOS/Windows newline format (linefeed + newline)
-m = convert file(s) to Macintosh newline format (linefeed)
-t = display current file type, no file modifications
This should convert all the Windows linebreaks to Mac.
Load the game and see what it looks like. If it's even worse, revert back to your backup directory.
