If your Horizon device is not connecting to Horizon Control after installing the software and driver, check the following macOS settings.
Allow Local Network Access for Horizon Control
Horizon Control requires access to your Mac's local network in order to communicate correctly with the Horizon Thunderbolt driver and connected Horizon devices.
If Local Network access was not allowed when Horizon Control was first opened:
- Open System Settings.
- Go to Privacy & Security > Local Network.
- Find Horizon Control.
- Make sure access is enabled.
After making this change, please restart your Mac before opening Horizon Control.
Once your Mac has restarted, open Horizon Control and check whether your Horizon device is now detected.
Check That the Horizon Driver Extension Is Enabled
In some cases, the Horizon driver extension may appear to have been allowed during installation but may not actually be enabled.
If your Horizon device is still not connecting:
- Open System Settings.
- Go to the macOS Login Items & Extensions settings.
- Check that the Horizon driver extension is enabled.
- If it appears disabled, enable it.
- If enabling it does not initially take effect, open the extension settings again and allow the Horizon extension once more.
After making this change, please restart your Mac before opening Horizon Control.
Once your Mac has restarted, open Horizon Control and check the connection again.
Check That Horizon Control and Firmware Are Up to Date
If your Horizon device has not been updated since installing the latest driver, it may not be able to connect to Horizon Control. Make sure Horizon Control and the firmware on your connected Horizon devices are up to date.
1. Open Horizon Control.
2. From the menu bar, go to Help > Check for Horizon Updates.
3. If an update is available, select Update when prompted.
4. In Select Devices To Update, add the Horizon devices you want to update, then select Update. Keep each device connected and powered on until the update has completed.
5. When Firmware Update Complete is shown, select Finish.
If the connection is not restored after updating Horizon Control and the firmware, restart your Mac, then open Horizon Control again.
If Horizon Control still does not detect your Horizon device after completing these checks, please contact Audient Support for further assistance.
