I don't have a Mac, so I can't get specific. But given that launching the tequila.exe file, or in this case re-launching it, serves to update the game, the solution seems to be to find wherever the CoH folder is installed on your system, double-click the file, and have the update installed. That will result in a launchable version of the game.

There was an update to the game, so don't try to run it from the old icon that's likely sitting on your desktop or in your tray. Double-click the tequila.exe file again, from within the COH folder, which will launch the game and install the update. After that, you should be able to get in without difficulty.
