Avernum 4 Windows Version History

v1.0 - Initial Release

v1.0.1 - Bug-fixing update

  • It is no longer possible to enter the Scree Caves from the hidden bandit fort near Fort Saffron. Doing so could cuase problems.
  • The game should do a much better job of sharing system resources when in the background.

Support for Macintosh

We have upgraded Avernum 4 for Macintosh to v1.1.2. The v1.1.2 update fixes problems with the graphics in the new Leopard operating system. Getting the new version is strongly recommended if you are using Leopard. No patch is available, download the full demo to upgrade.

Other Macintosh Issues

Running the Game on Mac OSX 10.12 or Later

This game does not work on MacOS Catalina (10.15.x) or later. Apple has decided to drop support for all 32 bit apps, so this game has completely stopped working on new Mac systems.We hope to someday remaster this game to be 64 bit and to work on the latest versions of the Mac OS, but it’s a large job and it will take a while to get to it.

For older Mac OS v10.12 to 10.14, this game can still run but with a few extra steps:

  1. Go to your Applications Folder on your hard drive. Open the Avernum 4 ƒ folder.
  2. Control-Click the Avernum 4 v1.1.2 application. From the pop up menu, select Show Package Contents.
  3. Open Contents folder and then MacOS folder.
  4. Control-Click the file Avernum 4 (Univ) Release, and select Open from the pop up menu.
  5. This will open a terminal window and should launch the game automatically as a process of that window. Do not close this terminal window (that would quit the game.) If the game window is under other application windows and is inaccessible, select Command-Tab to cycle through your applications.
  6. Game should run normally.

Reactivating the Cheat Codes
for Macintosh and Windows

You can turn off the character editor permanently. Should you have done this and want your character editor back, this is how to restore it: If using a Macintosh, throw away the "Avernum 4 Prefs " file in the Preferences folder. If using Windows, delete the "Avernum 4 Settings" (or "Avernum 4 Settings.dat" if you changed the settings to turn on file extensions) file in the Avernum 4 Data folder. Please note if you have registered the game, this might unregister it. If your game becomes unregistered, contact us for a new key by calling 206.789.4438 or emailing spidweb@spiderwebsoftware.com. There is no charge for this but please include the name you registered under, which game you need a new key for and your current registration code (located in the lower right hand corner of the title screen).
