Limited Availability: Uninstall Horizon Agent from macOS

Uninstall Interactively

1. Run the uninstaller application included in the original installation package.
2. Follow the prompts to complete uninstallation.
3. Restart the macOS machine.

Silent Uninstall

To uninstall Horizon Agent silently, mount the original installer and run the uninstaller from the Terminal with the --silent argument.

1. Open the original Horizon Agent for macOS installer to mount its disk image.

2. Open a Terminal window.

3. Confirm the exact mount point name under /Volumes/ before proceeding:

   ls /Volumes/
   

   Note: macOS assigns the trailing numeric suffix (for example, Horizon Agent for macOS 1) dynamically at mount time to avoid a name clash with an existing volume. This suffix is not guaranteed to be 1 and may differ or be absent depending on what else is mounted on the machine. Always confirm the current mount point before running the uninstall command.

4. Run the following command, substituting the confirmed mount point:

   sudo open "/Volumes/<confirmed-mount-point>/Uninstall Horizon Agent for macOS.app" --args --silent
   

Remove Residual Configuration

After uninstalling Horizon Agent, remove residual configuration files if needed:

1. Delete the Horizon Agent configuration and log directories:

   sudo rm -rf "/Library/Application Support/Omnissa/Horizon/"
   sudo rm -rf "/Library/Logs/Omnissa/Horizon/"
   

2. Delete the machine configuration file:

   sudo rm -rf /etc/omnissa/machine-cfg.cfg
   

Remove MDM Profiles

If the macOS machine was enrolled in an MDM solution, remove the PPPC profile after uninstalling Horizon Agent:

• Workspace ONE UEM: Unenroll the device or remove the Horizon Agent privacy profile assignment.
• Jamf Pro: Remove the configuration profile from the device record.
• Microsoft Intune: Remove the device configuration profile assignment.
