If TripMode does not activate when tethering

The best way to make sure that TripMode turns itself on automatically when tethering, is to connect your Mac to your hotspot, and turn TripMode on while it is connected to it. That’s it: TripMode will remember to activate itself automatically on that hotspot the next time you connect to it.

TripMode can detect most tethering situations automatically and activate when required. Nevertheless, some configurations prevent the detection from being successful:

In those cases, use the manual activation button in TripMode’s window to indicate your choice. Main window, inactive, activation button

This setting will be remembered the next time you connect to the same network so that you only have to set it once.

Please note that if TripMode activated by itself and you turned it off, it will also keep this setting as well. If you experience issues where automatic activation does not take place anymore, you may have turned TripMode off manually at one point. In that case, simply reactivate it and the setting will be remembered.
