That totally breaks my use case for Little Snitch: working tethered. When I tether my laptop it thinks it has free reign with the bandwidth and all of the little background processes can kill my data in a few minutes. With a firewall, I can grant access to only the processes that I need to get my work done.

Now, I guess I have to run some external firewall between my laptop and my phone. ... or better yet, abandon Apple.

Yeah, I tethered my MBP on the train and it used my entire 4GB data plan in about 15 minutes downloading an OS update.

Glad to know stopping shit like that is no longer an option.
