Issues unresolved[edit]

You can work around many glitches by using game's character editor.

Issues fixed[edit]

Black screen with only sprites visible[edit]

When transferring old save games, this can happen because the game acts as a demo and a registration key is required (this does not happen on GOG.com version of the game).

Performance issue on Intel OS X Tiger[edit]

This shouldn't be a problem on OS X Leopard. Upgrading to the new operating system will solve the problem, as long as your machine can run in Thousands of Colors mode.

No CarbonLib error[edit]

If you get an error that you don't have CarbonLib installed, your machine is missing the software that let's you run OS X compatible application. Fortunately, you can download this software here.

Installing from CD on Vista and later[edit]

If you have problems, follow these steps:
CD on Vista and later[citation needed]
  1. Open "Computer" in the Start menu, right-click on the CD and select Explore.
  2. Run the installer program (the application that has Install at the beginning of the name).

Screen Freeze Bug On OS X[edit]

Screen Freeze[3]
In recent versions of OS X, game's graphics might occasionally freeze for a small number of users. The game is playing in the background and sound effects are still happening, but the graphics are no longer refreshed on the screen.
  • Solution: When the screen freezes, type Shift-R. This should enable you to resume the game normally.

Installer/game not launching correctly on newer Macs[edit]

Renaming to .app[citation needed]
Avernum 3 might not run properly on newer Macintoshes and trying to run the game/installer will give an error. This problem is caused by the name of the program not ending in .app.
  • To fix the problem, change the name of the program so it ends in .app. If you are trying to run an installer from a CD, copy it to your machine, change the name so that it ends in .app, and run it.

Reactivating Character Editor[edit]

Character editor[citation needed]
  • Macintosh: Throw away the "Avernum 3 Prefs" file in the Preferences folder.
  • Windows: Delete the "Avernum3.dat" file in the Avernum Data folder.
If you have registered the game, this might unregister it. If your game suddenly becomes unregistered, see Requesting a new key.

"Requires admin privileges to run" when installing CD on Mac[edit]

Admin privileges[citation needed]
  • First solution: Install the demo and request a new key.
  • Second solution:
  1. Open the Install file. A window will open with the game art and an installer with the game icon. It will have a name like "Install Avernum 2 (Full)". Drag this installer onto your desktop.
  2. Hold down the Control key and click on the installer and select "Show Package Contents."
  3. Open the Contents folder and then the Resources folder.
  4. Open the file "installscript" If it asks you what program to open it with, choose TextEdit.
  5. Scroll down until you find these lines and change it to FALSE:

Require Authentication


  • Save and quit. The installer should now work.

Other information[edit]

Backing up the registration key[edit]

If you want to play the game with the same key, transfer the "Avernum3.dat" file (Windows) in Data folder or "Avernum 3 Prefs" (OS X) located in the Preferences folder (inside the Systems folder on your hard drive) to a safe place.

Requesting a new key[edit]

If you have lost a registration key, go to this page or e-mail the developer to get one.[4] Be sure to add:
  • The game title
  • The complete mailing address you ordered the game under (NOT an E-mail address)
  • The new game and/or editor registration number the game is giving you now
  • Windows or Macintosh version
