- Managing Metered Connections on OSX 5 answers
When on the road, I would like to use my phone's LTE connection and tether it to my macbook.
However, I do not have an unlimited data plan, so I don't want the mac to download a bunch of stuff (OS X updates, Chrome updates, and so forth) and kill my monthly allowance.
As far as I know, when tethering from the mac side it looks like a regular wlan connection, so I am not sure if there is an easy way to do this. I use Little Snitch, so I was considering creating a restrictive profile there to block connections when in this mode. Is there an obvious way to do this that I am missing?
