Thank you for the answers.
I was in the countryside where the connection speed tends to be slow and no ISP offers better connection in those areas.
So that's why it would be helpful to offer functionality allowing you to restrict bandwidth usage to only essential communication (Even if you don't need it 99% of the time, there are times when this would be amazing to have)
Is there a wishlist anywhere on the apple site where one can vote for features (or create them) to be implemented?
*I'm new to macOS and I generally like it, but sometimes I want to bang my head against the wall with the way some functionality is implemented (or it's just missing)
