mac-ops - Big Sur

Before you can build anything, you first need the tools. Herein lies automation to build a great (opinionated) MBP with a base configuration to support Systems Engineering (SRE/DevOps) work.

This always needs refactoring but it's still better than starting from scratch. If you find value in it, please feel free to fork/use it.

Attention! This may not be for you.

Documentation

Before jumping in, you should probably check the docs in the wiki first.

If this is your personal laptop that also serves as your work machine, a backup procedure is strongly recommended; check the rsync-backups page. The restore process in the bootstrap.sh script relies on a consistent backup. If this is a new macOS laptop/install for work, you can safely skip the rsync step.

Pre-Game

Make sure the ssh keys associated with your GitHub account work as expected:

% ssh -T [email protected]
Hi yourUserName! You've successfully authenticated, but GitHub does not provide shell access.

Clone the repo down to your laptop:

git clone [email protected]:todd-dsm/mac-ops.git && cd mac-ops/

CONFIGURE YOUR VARIABLES

vi my-vars.env

Assuming this is a fresh macOS, run the install prep script to:

• Get the latest OS Updates
• Configure sudo properly
• Installs include:
  • Homebrew
    • The Xcode CLI Tools are installed as a dependency
  • The GNU variants of common programs (sed, bash, find, awk, etc.)
    • Configures the system to
      • favor the GNU programs.
      • display man pages for these programs
• Afterwards, the install log is saved with some other app-related details.

tools/install-prep.sh 2>&1 | tee /tmp/install-prep.out

When it's all over, you will see something like:

         __                                     __   
  ____  / /_     ____ ___  __  __   ____  _____/ /_  
 / __ \/ __ \   / __ `__ \/ / / /  /_  / / ___/ __ \ 
/ /_/ / / / /  / / / / / / /_/ /    / /_(__  ) / / / 
\____/_/ /_/  /_/ /_/ /_/\__, /    /___/____/_/ /_/  
                        /____/                       ....is now installed!

To back out of the new Oh My ZSH shell just press: CTRL+d

The messages should advise you to reboot.

Kick-off

Once you're all backed-up, auto-magically configure the new macOS.

Kick off the script: (~32 minutes to complete)

./bootstrap.sh TEST 2>&1 | tee ~/.config/admin/logs/mac-ops-config.out

NOTE: remove the argument TEST to go live.

Post-Game

• Import your Terminal profile, if you have one.
• Finish any outstanding System Preferences configurations.
• Close all of your windows.
• Reboot the system

Then you're ready to start working.
