How do I remove "gamecontrollerd", "AXVisualSupportAgent" and "ViewBridgeAuxiliary" processes from being a passive listener on key tap events?

About gamecontrollerd

It is related to Chrome/Chromium (and so, to every electron application) - I've never saw it running before the Big Sur upgrade.

In my case, when I start the Mac, there is no gamecontrollerd process running, but when I launch Chrome or any Electron App (like slack), it starts.

Note that it is not possible to kill this process until you quit Chrome and all you electron based applications.

With BigSur I too noticed gamecontrollerd taking more than zero cpu cycles, I don't ever need it.

This shell command will keep it from starting when Chrome (or anything else) wants it:

sudo launchctl unload -w /System/Library/LaunchDaemons/com.apple.GameController.gamecontrollerd.plist

And if you decide to undo the change:

sudo launchctl load -w /System/Library/LaunchDaemons/com.apple.GameController.gamecontrollerd.plist

This worked for me, but of course your milage my vary. And as always, be careful when using sudo.

The safest solution would be to uninstall Chrome entirely and use another browser. If you don't like Safari give Firefox a try. It's a lot more secure and noninvasive that Chrome.
