Zumo 32U4 is not allowing me to use trackpad

I am using a Pololu Zumo 32U4 robot with a Mac that has OS X El Capitan (10.11.2) and when I plug the robot in my track pad stops working. I have installed the Arduino IDE and the libraries twice and I am 99% sure that I have done this correctly both times. I am wondering if anyone else has had this issue and if they have been able to rectify it.

Thanks,
Alex

Hello, Alex.

The issue is likely caused by the fact that sketches on the Zumo 32U4 present an HID interface to the computer. (For more information, see “The A-Star 32U4 USB interface” section in the A-Star 32U4 User’s Guide.) Can you run sudo dmesg in a Terminal after plugging in the Zumo to your Mac and post the output here?

We looked at your output and did not find anything informative. However, we did a quick search on the Internet and found that Mac OS X has an option that disables your trackpad when another mouse or wireless trackpad is detected. Can you go to System Preferences->Accessibility->Mouse & Trackpad on your Mac to see if the option “Ignore built-in trackpad when mouse or wireless trackpad is present” is check marked? If so, please uncheck that option and see if that fixes the issue.

That worked! Thank you so much! You guys are fantastic!
