  1. Download the ET Legacy Mac installer on
  2. Once the download is completed, open the installer by double clicking "ET Legacy v2.76.dmg". A new window appears.
  3. Just drag the ET Legacy App onto the Applications folder on the opened window. If you haven’t got admin rights, you’ll most likely be asked to enter your password.

  5. After downloading, open the installer of Wolfenstein ET by double clikcing "WolfET.2.60d.dmg" and accept the license agreement.
  6. Another window will pop up, containing a folder called "Wolfenstein ET", which in turn contains the etmain folder we’re looking for.
  7. Copy the pak0.pk3, pak1.pk3 and pak2.pk3 from the etmain folder either by Edit→Copy or pressing ⌘C on your keyboard.
  8. Open the Application folder on your finder and search for the ET Legacy app.
  9. Depending on your OS X version, you can CTRL+click the app symbol and either go for "Show Package Contents" or "Open in a new Tab"
  10. Now you can open the etmain folder of ET Legacy and paste the previously copied pk3 files by Edit→Paste or by pressing ⌘V.

Open your Applications folder, then open the Utilities folder. There you’ll find the Alternatively you can use Spotlight to look for "terminal". Type in the following line (or copy/paste it) and press enter:

cd /Applications/ && xattr -dr ET\ Legacy/

As no success message will appear, you can close the terminal again. The app is now allowed to use its known file structure and thus, finding the correct game data. You can start the game without further interruptions.
