My MacBook is basically unusable right now. This appears to be the reason. Is there any way to fix it without installing little snitch? Edit: working as usual now, moments after i wrote this. But seriously Apple, how can you allow this to happen? Your services hanging should _never_ prevent my device from running things locally. This is seriously making me reconsider my next computer purchase.
Turn off your internet, open the app, turn it back on.
And people somehow still love their macs...
