Ignore built-in track pad not working
I'm still have a problem in 12.4 with the Accessibility option Ignore built-in track pad when mouse or wireless trackpad is present. I'm using the standard apple wireless Magic Mouse 2. When the mouse is connected the trackpad still picks up movements. Sometimes after a reboot it works but other times not. Uncheck the check box and re-checking makes no difference. It seems this problem has been around for a long and should be fixed.
