Finally decided to convert to the penguin. I have live booted mint from a usb, without installing it yet, on a macbook pro 2017. But none of the WiFi networks in my apartment are showing, except for a few weak ones. Help a newbie out :)

Edit: To clarify it is not installed yet. Just used it from a live usb.

Edit 2: Used phone as tether for internet and went through all managers. But none had any updates that worked. I also tried installing b43 and after that wl. But both did nothing on the live usb boot, I assume since modprobe doesn't do anything on a live boot. But I ain't installing if it won't even work on the live boot.

@RedNight left a link that suggests this macbook, version 14.2, wifi doesn’t work with linux. https://github.com/Dunedan/mbp-2016-linux

Final edit: Fedora also didn't work. So it's a hardware compatibility issue.

TLDR: If u have a macbook 2017 version 14.2 the wifi won't work on linux so don't try.
