How to Install Minecraft on a School Computer

Heads up: There's a chance that trying to run MultiMC on a Mac will give you an "untrusted program" warning. There doesn't seem to be anything I can do to get around this but it only happens on some computers. Windows users should be fine.

Yeah but if my school block request (or packets, I don't know how it really works) from Mojang, and I can't login because of that, do you have a solution?
