Initial Jeppesen Distribution Manager (JDM) installation is handled by a self-contained installer package available from support.jeppesen.com. Follow this link to download and install the latest JDM version for your Mac computer.

To download and install the JDM software, follow these steps:
Administrative privileges are required to install this application and application updates. You must have permission to create directories in the /Applications folder and permissions to create directories in your HOME folder. In a corporate environment, the IT department can change this permission status.
Launch the JDM shortcut from Applications or Launchpad.
Check the box to Save Password, if you don't want to enter your user name and password every time you open JDM.
Click on the drop down arrow next to your user name and customer number.
Select Logout.
If you prefer to exit the application but remain logged in, go to the JDM menu in the upper left corner and select Exit.
A JDM uninstall application is provided as part of the standard install. The uninstaller resides along side the JDM application in the Applications folder. The uninstaller is a smart application and removes the JDM application, agent list file, package receipts, and your user data folder. All deleted items are NOT recoverable from the Trash.
Locate the JDMUninstall in the Applications folder, LaunchPad, or Finder and double-click to run it.
Enter your Username and Password.
Click Uninstall.

Click Close.
