Issues fixed[edit]

DirectX issues[edit]

To ensure the original game and its expansions run properly, install the latest DirectX End-User Runtimes. This is not a problem with the Complete Edition, which installs the correct DirectX version automatically.

Failed Initializing Python[edit]

Caused by discontinued support for Python 2.3 in OS X Yosemite 10.10.
Copy Python 2.3 back into OS X[4]
  1. Download BTS YosemitePython Fix.7z.
  2. Copy the folders '2.3' and '2.5' to /Library/Python/. Enter your administrator password.
  3. Navigate to /System/Library/Frameworks/Python.framework/Versions/ and delete the alises for '2.3' and '2.5' and copy in the '2.3' and '2.5' folders from the BTS Yosemite Python Fix.
