«Thank you for contacting Aspyr Tech Support!
Unfortunately Indiana Jones and the Emperor's Tomb was not developed for Mac OS X 10.5.1 Leopard.
Games that were developed for a previous Mac OS, as this one was, may have many problems running on Mac OS X 10.5.1 Leopard. Unlike PC operating systems the Macintosh operating systems have video card driver and other updates built in, and this can cause problems we cannot immediately fix. Thus, this game is not supported on Mac OS X 10.5 Leopard. We will be working diligently with Apple to get these issues resolved if possible. Please keep in mind that there are some things that can only be fixed by Apple, and we will be in direct contact with them to fix the issues that can be fixed. Please feel free to let us know of any problems you are having relating to our games and their ability to operate in Leopard. It will take some time for us working with the new OS and our customers to identify issues and make the necessary patches as needed.»
