Install the LEM Agent on Mac OSX 10.7 and later

Updated: April 26, 2018

See LEM Agent installation preflight: prepare to deploy LEM Agents for Agent download information and a pre-install checklist.


Installation notes for the Mac OS X installer

  • The plist file used to start the version 5.3.1 Agent contains incorrect values, and does not work as expected. This is a known issue that will be fixed in a future release.

  • A reboot is not required following installation.

  • LEM Agents are installed in /Applications/TriGeoAgent/ folder by default.

    To run as a service and start automatically, the LEM Agent also uses the following folders:

    • /System/Library/StartupItems/
    • /Library/LaunchDaemons/
  • Mac OS X 10.7 or later is required to install the Agent.

  • Java Runtime Environment (JRE) 1.5 or later is required to install the Agent.

You will need to temporarily disable the System Integrity Protection (SIP) on Mac OS X. Apple does not allow root access on operating systems after version 10.x, however, root access is necessary in order to copy LEM Agent files to /System/Library/LaunchDaemons/.

Run the LEM Agent Installer on Mac OS X

To run the LEM Agent installer on Mac OS X:

  1. Extract the contents of the installer ZIP file to a local or network location.

  2. Run, and then click Next to start the installation wizard.

  3. Accept the End User License Agreement if you agree, and then click Next.

  4. Enter the hostname of your LEM Manager in the Manager Name field and click Next. Do not change the default port values.

    Use the fully-qualified domain name of the LEM Manager when you deploy LEM Agents on a different domain. For example, enter:

  5. Confirm the Manager Communication settings, and click Next.

  6. Confirm the settings on the Pre-Installation Summary, and click Install.

  7. After the installer finishes, click Done to exit the installer.

    Ignore the error message that says some errors occurred during the install.

Next steps:

To configure the LEM Agent as a Mac OS X service and set it to start automatically

  1. Copy /Applications/TrigeoAgent to /System/Library/StartupItems/

  2. Modify the plist file packaged with the installed Agent by performing the following:

    1. Navigate to /System/Library/StartupItems/TriGeoAgent/StartupFiles/TriGeoAgent/

    2. Open com.trigeo.trigeoagent.plist in a text editor.

    3. In the file, replace /Applications/TriGeoAgent/ with /System/Library/StartupItems/TrigeoAgent/

    4. Save the file in /System/Library/LaunchDaemons/.

  3. Change the permissions on the plist file. This only needs to be completed if the plist file is moved with a non-root account.
    chown root:wheel

  4. Restart the computer.

  5. Run ps -ef | grep -i trigeo to verify that the Agent starts automatically after the computer restarts.

To start the LEM Agent on Mac OS X manually

  1. Configure the LEM Agent as a service and set it to start automatically. See the previous section.

  2. Open Terminal.

  3. Enter launchctl load /Library/LaunchDaemons/com.trigeo.trigeoagent.plist

The LEM Agent continues running on your computer unless you uninstall or manually stop it. It begins sending alerts to the LEM Manager immediately.
