# A macOS dev env setup script updated for a Big Sur 
# install (08/2021). There isn't anything macos specific in here 
# though, i just haven't tested it elsewhere. 
#
# I have a seperate script that setups a fresh macOS install with
# a useful set of software applicatiions that you might want to run
# before this one. 
# Link to macos-software-bootstrap.sh:
# https://gist.github.com/jousby/18950c84b21341d48c5c1710065ef96b
#
# DISCLAIMER: This script hasn't been designed to be run more than once.
# If you have failed steps during the first run then you will need
# to manage retrying the failed parts on your own.
