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"
Restart your computer and plug in your SideTrak!
Screen Recording Permissions
macOS Catalina 10.15 requires the user to permit "Screen Recording" in order for DisplayLink devices to work properly. The message is generated by the OS and the screen is not actually being recorded by DisplayLink. Approving it enables the DisplayLink driver to access the pixels it needs to render a mirrored or extended screens, and send the pixels over USB from your computer to the DisplayLink display. It does not send any data or pixels back to DisplayLink.
To approve the permission, please follow these steps:
2. Reboot your system.
3. Open System Preferences.
5. Go to Privacy.
9. Click on the Lock again to save changes.

Mac OS X System Does Not Boot Correctly
This is an extremely rare case, and can occur due to the following reasons:
- A newly installed Mac OS X update is not compatible with a preexisting DL driver
- A newly installed DL driver is not compatible with the installed Mac OS X version
- A third party kernel extension or application loaded at boot is not compatible with the DL driver
In these cases the solution is to shut down the computer by pressing the power button for more than 5 seconds. During reboot hold down the shift key for approximately a minute, this will invoke a safe boot. A safe boot will take considerably longer than usual.
No third party kernel extension or application will be loaded during safe boot and automatic login will be disabled, so the user will have to log in to their account.
Once logged in, the user should run the DisplayLink uninstaller, and reboot. After reboot the user should then try to install the latest DisplayLink driver, or third party kernel extension, which should hopefiuly resolve this issue.
