If you are still experiencing connectivity issues, we recommend completing the following system preference updates.

System Preference Updates


Some Macs have stricter security policies that requires a few extra DisplayLink installation step. Follow these steps to connect to your SideTrak! 

Note: Be sure that you have installed DisplayLink within the past 30 minutes. If this is not the case, you will need to uninstall and reinstall the software. 

Open your security settings (Settings Preferences -> Security & Privacy -> General)

Unlock and authenticate security changes if your device requires it.

Find "System software developer DisplayLink Corp was blocked from loading" and click "Allow"

If you don’t see an option to “Allow”, click into the Privacy tab, then Acccessibility, and check the box next to DisplayLinkUserAgent.

Your screen will not actually be recorded by Displaylink, approving this just allows DisplayLink to extend and mirror the pixels to the SideTrak monitor. 

Restart your computer and plug in your SideTrak! 


DisplayLink Diagnostics

If you have completed all of the troubleshooting steps and are still experiencing connectivity issues, we would like to run a DisplayLink Diagnotic on your device to identify an alternate solution.

  • Download and run the Mac DisplayLink Support Tool. 
  • Connect the SideTrak to your Mac 
  • Click on "Collect Info" 
  • The system information will gather into a zip file on your device and may take a few minutes.
  • Close the tool and send the zip file to us at with the subject link DisplayLink Diagnotics Mac and a brief explanation of your issue

We will work with the DisplayLink IT team to find a solution for you.
