A Mac User's Best Friend!/PLEASE READ BEFORE POSTING ANY NEW PROBLEM THREADS!!!!!!

You need to install the Base game first. Download the Super Patch (found in another thread at the top of this forum) and make sure your game is up to date. Next install each EP and SP you have in release order (found at the bottom of the launcher by icons). Install each EP, start the game and make sure it runs. If it does, then you're good to install the next one and so on. You should take a moment and read over the three threads listed on the first page of this one thread. It has many handy tips and tricks to keep your game running smoothly.
