I'd like to use my iPhone SE as a hotspot for my rMBP. I've decided to work remotely at a local park, given I normally work at home.
Whenever I turn on my Mac, it apparently eats through mBs of data, as related by Little Snitch. I don't even know what it's doing - but it doesn't matter at home.
But setting up a mobile office, I'd like to restrict ALL activity to the most bandwidth "stingy" browser - which I believe is Opera. I can just handle email through my phone - as I'm guessing that Mac's native Mail chews through data like nobody's business.
Anyway, I'd like to shut absolutely everything off when using my mobile hotspot, other than Opera - or whatever browser any of you might suggest. No Mac system BS filtering through and eating up data.
Thanks very much for any help and advice.
