Day 0 - Bootstrap MacOS with Ansible

After factory resetting the maching you will need to do the following things to bootstrap it with Ansible.

• Set default shell to bash chsh -s /bin/bash (optional)
• Open the App Store and sign in (but do not install anything)
• Install command line tools
  • xcode-select --install
• Add Python 3.8 to the $PATH
• export PATH="$HOME/Library/Python/3.8/bin:$PATH"

# The default BAR address space available on the CM4 may be too small to allow
# some devices to initialize correctly. To avoid 'failed to assign memory'
# errors on boot, you can increase the range of the PCIe bus in the Raspberry
# Pi's Device Tree (a .dtb file specific to each Pi model).
#
# You should probably read up on Device Trees if you don't know what they are:

# Attempt to set up the Nvidia GeForce GT 710 on a Pi CM4.

# I have tried both armv7l and aarch64 versions of the proprietary driver, in
# addition to the nouveau open source driver (which needs to be compiled into
# a custom Raspberry Pi kernel).
#
# tl;dr - None of the drivers worked :P
