Can I play this game on a case-sensitive file system?
No. Tropico 4: Gold Edition has been tested with the basic formatting option for Mac OS X, which is HFS+. This system is not case-sensitive and identifies files by name without checking capitalization.
The capitalization of filenames is not consistent throughout the game. While this will not always prevent the game from running on case-sensitive file systems, it may lead to crashes and other unpredictable behaviour.
If you have to run a case-sensitive setup and you experience problems with Tropico 4: Gold Edition, please install the game on a standard formatted partition or read/write disk image. In most cases this will allow you to play the game on your machine.
