Crunchbang was such a good distro! I ran linux for about seven years. Ubuntu and then Crunchbang. Had my 2012 MacBook Pro dual boot into Crunchbang. Battery life was awful. It had no automatic fan control, so the laptop got so hot I could barely touch it. I ended up writing a bash script to manually control the fans using function keys https://gist.github.com/nwjlyons/b29ee6f7e26595f55a2a
As cool as it was, I can't be bothered with any of that these days. Just give me a Macbook Pro, as I know it will work and have amazing battery life!
