Block Internet access to specific apps on specific Wi-Fi networks My company just set my laptop up with Backblaze, and the backups are killing my crappy rural DSL connection when I bring the machine home. Are there utilities that can block specific applications from accessing the Internet on specific Wi-Fi networks?

I've seen recommendations here for apps like Little Snitch or Radio Silence that can control Internet access on a per-app basis, but they don't seem to say anything about specific Wi-Fi networks. Can Automator control these apps when connecting/disconnecting from a specific Wi-Fi network?
Try TripMode, https://www.tripmode.ch

It is specific-network-aware, so you can activate it when you are on the constrained network, and after that it will remember, and auto-activate itself there.
