Using a magic trackpad with multiple macos devices is a mess This is why I created this little script to switch between devices simply executing an application

To do this I'll need:

  • Install blueutil
    • You can simply run brew install blueutil
  • Edit the toggle-magictrackpad.sh file and replace:
    • The MAC addresses with your devices
      • You can find the MAC address of your device by running blueutil --paired
    • blueutil's path if you installed it in a different way
      • you can find with which blueutil
  • Open Automator
    • Create a new Application Type document
    • Select "Run Shell Script" from the left panel
    • Paste the content of toggle-magictrackpad.sh into the script box
    • Save whenever you want

Now you can simply run the application and it will switch between your devices. You will be able to find it in the spotlight search too.
