Before everything

Download dotfiles-master (because you still don't have git): https://github.com/icaromedeiros/dotfiles/archive/master.zip

Update software:

sudo softwareupdate -ia --verbose

Install brew

To be safe, follow instructions from brew.sh or use:

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

Install Python / Pyenv

Install Python first than others formulas sh python/python.sh

Brew packages install

sh brew/packages.sh
