    • Java 8 (Java may be downloaded from here).

    Troubleshooting Notes:

    • For Mac OS X El Capitan version 10.11, some users reported problems starting GeoMapApp. Ensure that the latest El Capitan bug fixes have been installed, delete your .GMA file (see step-by-step notes here), and restart GeoMapApp.
    • If the default Java-bundled version does not work, please try installing the unbundled version here (requires 60 MB of disk space.)
    • If you installed GeoMapApp, and dragged it to your Desktop or Applications folder but it does nothing when double-clicked, please check the requirements above. You may need to download a newer version of Java - see this step-by-step guide in our FAQ.
    • For Mac OS X Mountain Lion version 10.8 users who might be having issues with installing the application you must configure your default Security & Privacy settings to accept the application. Go to the installation walk-through for more details.
    • The older Mac OS X operating systems Mac OS X Snow Leopard version 10.6, Mac OS X Leopard version 10.5 or Mac OS X Tiger version 10.4 require Java 5 or lower. Try using our past versions here. Mac OS X Panther will not work.
    • When running on Mac OS X Lion version 10.7 and Mountain Lion version 10.8, Apple's new Gatekeeper security may keep GeoMapApp from opening. To fix this: In the Finder, Control-click or right click the GeoMapApp icon. Select "open" from the menu that appears. Click "open" in the resulting dialog box.
    • If your system meets the minimum requirements but you are still unable to run GeoMapApp, please tell us.
