Error Writing to Device on Mac

If you are having the error "Error connecting to device" when trying to write to the devices, make sure you are launching the software from the Terminal App with the following command: 

sudo /Applications/KeyMouse_3.app/Contents/MacOS/keymouse-darwin

You will need to add "Terminal" (or whatever program you are launching the software from) into Settings > Security & Privacy > Input Monitoring to give the OS permission to write to the KeyMouse Devices. If you are on an older version of Mac then you will need to add Terminal to Settings > Security & Privacy > Accessibility. We have tested and without adding this, it will not write to the devices.
