If the installation of GECAMed fails on Mac OS-X, the root user may not be activated on your system or you have the wrong Java version for the JBoss.

This is how to enable the root account on OS-X:

1. Open the “Directory Utility”, located in the “Utilities” folder within the “Applications” folder.
2. Click the lock to make changes. You will need to enter an administrator name and password.
3. From the Edit menu, select Enable Root User.
4. Enter a secure password for the root user, then enter it again in the “Verify” field, and click OK.
5. Reboot your system.
   

1. Open the Directory Utility located in /System/Library/CoreServices/Directory Utility.
2. Click the lock to make changes. You will need to enter an administrator name and password.
3. From the Edit menu, select Enable Root User.
4. Enter a secure password for the root user, then enter it again in the “Verify” field, and click OK.
5. Reboot your system.
   

If you have Java version 1.6 or higher installed on your System (default on Mac OS-X 10.6), the JBoss might not be able to be installed and / or run correctly. To enable the JBoss to use the right Java version (i.e. 1.5), you can download and execute the change java linking script. You may be asked to enter the root password that you have assigned in the previous step. This script links all applications explicitly using java 1.5 (like the GECAMed JBoss server) to our own Java version in the GECAMed folder, which is a modified java 1.5.
You can reset the system defaults by downloading and executing the reset java linking script.

Now do a clean uninstall (see Uninstall GECAMed on OS-X) and reinstall GECAMed from scratch.

On Mac OS-X installations tend to be more complex then on Windows. If GECAMed is obviously not running after the initial installation, or an upgrade, try the following:

1. If there is no icon to start the GECAMed client it can be started manually by typing the following URL in Safari (on the same computer where GECAMed was installed): http://localhost:8080/gecamed
2. if this does not work, chances are that the main server component of GECAMed, the JBoss application server, is not running. To check whether JBoss is running or not type the following type the following URL in Safari (on the same computer where GECAMed was installed): http://localhost:8080
   If it works you'll see a welcome screen from the JBoss, otherwise the usual URL not found” error.
3. another way to test the availability of the JBoss server is by issuing the following command in a terminal session: ps -ef | grep java. The result should look similar to this:
4. If the JBoss isn't running, first try to reboot the computer. Next try to restart the JBoss manually, using the run.sh command.
