Limit what a tethered iPhone internet connection can be used for I have various background services running on my Mac which use quite a lot of bandwidth: Google Drive, a couple of OneDrive sync programs, iCloud sync, Dropbox, and Backblaze for a general backup of my harddrive.

This is fine when I'm on a regular wifi connection, but when i tether my Mac to my iPhone I have limited data -- only 4GB per month. I'd like to be able to limit the services which can use my internet connection when that internet connection is provided by my iPhone.

Is there a straightforward way to do this? I use Little Snitch and think I might be able to set up a specific profile for when I've connected via a tethered iPhone, but this seems quite complicated.
I had the same issue and have been using "Trip Mode" on my Mac to good use. Currently sells for about $10CAD.

What I need now is something that will do the same on my iPad...
