Aspyr Media Support Response Terry At times, updating the operating system can cause games to become glitchy. I recommend the following troubleshooting steps. Try running the Repair Disk Permissions function of the Disk Utility located in Applications/Utilities. Also, avoid installing the game to Applications or the Desktop; there are permissions conflicts that can arise when games are installed here. Games work best when they are installed in the Users/Shared folder or in a separate games folder on the top/root level of your hard drive. If the game is not currently stored in one of the two aforementioned locations then sometimes just moving the game is not enough and it is necessary to reinstall. Reinstalling also gets rid of any game data that may have become corrupt. Be sure to trash the game's preferences files located in Home/Library/Preferences and Home/Documents when you do so. Then just trash the current copy of the game and install a new copy. Then run the 1.0.2 patch again. Thanks for choosing SimCity
