Installing KensingtonWorks Trackball Software

Thanks to a recent flare-up of a shoulder RSI issue related to spending too much time mousing around on the computer, I recently picked up a Kensington Expert Mouse Wireless Trackball.

It works fine out of the box, and seems to be helping with the shoulder.

You’ll notice that it has four buttons. Only two work with the default mouse drivers on Mac OS. To get the functionality of the other buttons, you need to install the KensingtonWorks personalization software.

Here’s the trick: KensingtonWorks won’t recognize trackball unless you configure things in a very specific order that’s not documented anywhere I could find. At least that was my experience.

So here’s the correct order to set it up:

  1. Download and install the latest KensingtonWorks software.
  2. Restart.
  3. Start KensingtWorks.app. You may get some prompts about accessibility settings.
  4. Open System Preferences > Security & Privacy and unlock to change settings.
  5. On the General tab, click the button to allow KensingtonWorks.
  6. On the Privacy tab, go to Accessibility and click the box to allow KensingtonWorksHelper.app.

Now go to the KensingtonWorks app and follow the wizard steps to configure the trackball. You really don’t need to even take the trackball out of the package until this point.

For what it’s worth, I found that setting up with the USB dongle worked better than with Bluetooth.
