MacOS – Network usage whitelist for cell tethering on OSX

cellular-datamac-appstoremacosNetworktethering

I frequently use my Macbook on my iPad's data plan. Unfortunately, unlike iOS, OSX can't limit application network usage based on whether it's on a cell network, and I always have to remember to close Steam, uTorrent, Dropbox, automatic updates, etc. whenever I start tethering. Is there an app out there that I can turn on and off quickly to whitelist a small number of applications and prevent everything else from using the network?

TripMode was made specifically for this purpose, and even turns on automatically when connected to designated cell hotspots.
