Posted on 23 mins read


I’m an engineer with a new laptop, which requires setting up with various development tools and configuration. This post is my attempt to capture and document my process for getting a new dev environment set-up.

I used to try and automate a lot of this with bash scripts, but realised over time that things go out of date quite quickly (e.g. OS configurations can change substantially, as well as my preferred ways of working).

I also find that if an error occurs with an automated script (unless you’ve coded things defensively enough) you can end up with your machine in a weirdly broken state.

Given a straight forward set of instructions, doing things manually doesn’t take long at all, and you can modify things at that point in time without just blindly installing various things you no longer need.

Here’s a list of what we’re going to be discussing…


It’s good to begin by surveying your current system and understanding what you have already installed. For me this looked something like:

  • OS: macOS Mojave (10.14.4)
  • Curl: /usr/bin/curl (7.54.0)
  • Bash: /bin/bash (3.2.57)
  • Python: /usr/bin/python (2.7.10)
  • Ruby: /usr/bin/ruby (2.3.7p456)
  • Git: /usr/bin/git (2.20.1)
  • $PATH: /usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin

What’s worth me noting additionally here is that I primarily use two programming languages: Go and Python. The reason I mention this is because Python has an interesting history with the name of its binaries.

The binary name python generally refers to Python version 2.x. Where as Python 3.x has traditionally been named python3 to help distinguish the two. So looking above we can see which python reveals the location as /usr/bin/python and without checking the version (e.g. python --version) I was fairly certain it would be a 2.x version (based on the naming history).

This has been the generally accepted rule for a while, except! when dealing with tools that handle virtual environments.

For example, pipenv is a tool that helps you to manage not only different Python versions but also the dependencies installed for different projects (referred to as virtual environments). A tool like pipenv will proxy a command such as python through a shim script (e.g. /Users/integralist/.pyenv/shims/python) and that shim script will then determine which Python interpreter/binary to execute.

A shim script typically identifies the virtual environment you’re working under and will then figure out the most appropriate Python interpreter to invoke. So within that virtual env if you call python, then you may not necessarily get the Python2 interpreter, as your virtual env might be configured such that the expectation is to proxy your invocation to a Python3 interpreter.

This is why, when setting up a new laptop, getting a good development environment setup is essential because it can get quite confusing untangling a mess of default Python’s vs brew install ... versions of Python 3 and then subsequently using multiple environment tools like pipenv which confuse things further by hiding the actual versions behind the generically named python command.

The situation reminds me a lot of XKCD’s classic comic strip

Package Manager

Let’s begin our journey by first installing a ‘package manager’. This software will enable us to search and install various pieces of software. The macOS provides its own GUI implementation referred to as the ‘App Store’, but it’s heavily moderated by Apple and an app can only be found there if it abides by Apple’s own set of rules and criteria for what they consider to be ‘safe’ software.

Note: there are many apps that aren’t available in the App Store because Apple can be a bit anti-competition (see Spotify’s “time to play fair” campaign).

So we have to download our own package manager, and the defacto standard for macOS is a program called Homebrew (which is a terminal based tool, so no GUI). In fact, I’m not actually sure what alternatives to Homebrew exist (other than MacPorts, which if you want to understand the differences between it and Homebrew then read this)? On Linux you have tools such as yum or apt but for macOS you either use the built-in App Store or find your own alternative (so in this case, we’ll use Homebrew).

To install Homebrew, execute the following command in your terminal:

/usr/bin/ruby -e "$(curl -fsSL"

Note: notice that installation command uses the default installation of Ruby which Homebrew presumes is available (and for the most part is a safe presumption to make as Ruby as been provided by macOS for the longest time).

If you need to update Homebrew you can execute a brew update command, but the installation will install the latest version any way, so that won’t be necessary.

Essential Packages

OK, so I start with what I refer to as a ‘essential packages’, and specifically these are packages that do not require any configuration on my part. Meaning, I can install them and consider the job done, where as with other packages I install I’ll have to make some additional tweaks to (which we’ll see as we move on past the ‘essential’ segments of this post).

To install a package via Homebrew, execute the following command in your terminal:

brew install <package_name>

Here is a list of the packages I’ll install:

  • ag: a grep like tool (aka. the_silver_searcher)
  • gnu-sed: it’s the gnu version of sed (gsed) used for filtering/transforming text
  • jq: tool for parsing/inspecting json output
  • docker: useful for running containerized programs
  • hugo: static site generator (used to make this website)
  • node: server-side js programming language (used to compile a static search feature for my website)
  • pwgen: generates random passwords
  • reattach-to-user-namespace: used by tmux for clipboard storage
  • shellcheck: bash linter
  • sift: another command line search tool
  • tree: displays directory heirarchy structures as a tree
  • watch: executes given command every N seconds

Here’s a handy one-liner:

brew install ag gnu-sed jq docker hugo node pwgen reattach-to-user-namespace shellcheck sift tree watch

Essential Apps

Homebrew now allows you to also install GUI applications, not just command line tools, but to do this you’ll need to configure Homebrew to use Cask:

brew tap homebrew/cask

Once that’s done you can install an app via Homebrew using the command:

brew cask install <app_name>

Here is a list of the apps I’ll install:

  • alfred: like Apple’s Spotlight search, but better
  • caffeine: stops the Mac from going to sleep
  • dash: offline documentation
  • docker: this is the counter-part to the ‘package’ installed earlier †
  • google-backup-and-sync: syncs files between computer and Google Drive
  • google-chrome: web browser
  • keybase: encryption tool
  • lepton: GitHub Gist UI
  • slack: communication tool
  • spotify: music streaming service

† if you installed the docker ‘package’, then you need the docker ‘app’ as well for it to work. You can’t have one without the other (this is because the app sets up the interface for macOS to interact with the underlying docker client/server implementation).

Here’s a handy one-liner:

brew cask install alfred caffeine dash docker google-backup-and-sync google-chrome keybase lepton slack spotify

The Dash app will ask you what documentation you would like to download so it’s available offline. I use the following docsets (I used to have lots more but realised I never really used them, so this is my ‘essential’ docs list):

  • boto3
  • Go
  • HTTP Header Fields
  • HTTP Status Codes
  • Python2
  • Python3
  • Regular Expressions
  • tmux
  • Tornado
  • vim


I like to use a more modern version of curl (e.g. supports HTTP/2, and other features):

brew install curl

But in order to use this version of curl you’ll need to modify your $PATH:

export PATH="/usr/local/opt/curl/bin:$PATH"


Similarly to curl, I like to have the most recent version of git installed:

brew install git

Once that’s installed I configure it like so:

curl -LSso ~/
curl -LSso ~/.gitignore-global
curl -LSso ~/.gitconfig

Note: it’s always worth checking ~/.gitignore-global is up to date (i.e. not referencing file types I no longer work with).


To install and configure latest version of the Bash shell, execute the following commands:

brew install bash
echo /usr/local/bin/bash | sudo tee -a /etc/shells
chsh -s /usr/local/bin/bash

Also make sure to install auto-complete for bash:

brew install bash-completion

Finally, we’ll configure Bash like so:

curl -LSso ~/
curl -LSso ~/.bashrc
curl -LSso ~/.bash_profile

Note: ~/.bashrc references ~/.fzf.bash which is needed, and comes from installing the FZF vim plugin (which we’ll sort out shortly).


To install my custom terminal theme:

curl -LSso /tmp/Integralist.terminal
open /tmp/Integralist.terminal
rm /tmp/Integralist.terminal

Note: don’t forget to change the terminal font to menlo (if not already set) and also set Integralist theme as your default. I used to do this via defaults write "Default Window Settings" Integralist and defaults write "Startup Window Settings" Integralist but those have changed now in the latest macOS (see defaults read).


Let’s now set-up a new SSH key for GitHub access:

mkdir ~/.ssh
cd ~/.ssh && ssh-keygen -t rsa -b 4096 -C ''
eval "$(ssh-agent -s)"
ssh-add -K ~/.ssh/github_rsa

Don’t forget to pbcopy < ~/.ssh/ and paste your public key into the GitHub UI. Once that’s done you can execute the following command to test your SSH key is set-up correctly and working:

ssh -T

Note: there is a slight catch-22 here which is if your password for GitHub is in your Password Store (see next section), then that makes things trickier. For me I also have a copy of the encrypted store on my phone and so I can utilise that to access the password. But failing that, you can just ‘reset your password’ in GitHub UI’s and follow the email instructions to gain access and thus login and add your new SSH key.

Password Store

I use the open-source password store for handling secrets and passwords. This tool provides the pass command, and that requires the use of gpg, so let’s start by installing GPG:

brew install gpg

Now you have gpg, make sure you pull your private key from wherever you have it stored (e.g. external USB stick), then execute:

gpg --import <private-key>
gpg --export <key-id> # public key by default

Note: don’t forget you can sign your git commits:
git config --global user.signingkey <key-id>
But you might prefer to use a Keybase key for that instead.

Next, install pass and pass otp commands:

brew install pass pass-otp zbar

You can now pass a QR code into pass otp and use the terminal for generating one-time pass codes for 2FA/MFA authentication:

zbarimg -q --raw /tmp/qr.png | pass otp insert Work/Acme/totp/foo`  

pass otp -c Work/Acme/totp/foo

Note: installing zbar provides the zbarimg command

Lastly, we need to setup a new Password Store, and to do that we need to provide our GPG key id:

# <ref> needs to be your email, or part of the key's description
keyid=$(gpg --list-keys <ref> | head -n 2 | tail -n 1 | cut -d ' ' -f 7)

pass init $keyid

Now we can pull our Password Store from a private repository:

pass git init
pass git remote add origin
pass git pull
git branch --set-upstream-to=origin/master master

Note: I also like to ensure my encrypted datastore is sync’ed up to other online providers, and symlinked to ~/.password-store as well so changes are backed up automatically in multiple places.


We’ll install the latest version of go (as far as Homebrew is concerned):

brew install go

This is required because in order to handle different versions of go we’ll want to manually compile go, and that ironically requires a version of the go compiler.

Finally, make sure the default Go directory is set in your $PATH so that any installed binaries will be available:

export PATH="$HOME/go/bin:$PATH"


The macOS comes only with Python 2.x and although the specific version should (according to the Python docs) have the pip command available, that’s not the case. So we have to install pip for Python2 manually using the very old (but built-in) easy_install command:

sudo easy_install pip

Now when running pip --version we should see:

pip 19.0.3 from /Library/Python/2.7/site-packages/pip-19.0.3-py2.7.egg/pip (python 2.7)

At this point, in order to have a sane Python setup, we should look towards ‘virtual environments’.

There are three aproaches we’ll look at (each of them rely on pyenv):

  1. pipenv
  2. Poetry
  3. pyenv-virtualenv

We’ll start by showing you how to install pipenv which is a high-level abstraction across multiple tools (inc. pyenv and virtualenv), then we’ll move onto installing Poetry (which I prefer for reasons I’ll explain later).


There is a brew install:

brew install pipenv

This will install Python 3.7.3 for you and so it’ll be made available via python3 and pip3.

Pipenv can’t install Python versions for you. You’ll need a tool such as pyenv which can be installed like so:

brew install pyenv

Note: pyenv will also install python-build (no need to install that separately), but it’s useful to know because the version of Python you want to install will be based on what’s available from python-build --definitions.

So let’s set-up a new Python environment (remember installing pipenv resulted in python3 command being installed, and that’s specifically version 3.7.3, so we’ll install a different Python3 version to that):

mkdir -p ~/Code/Python/3.7.1
cd ~/Code/Python/3.7.1

pyenv install 3.7.1

pipenv --python 3.7.1
pipenv install boto3 pytest structlog tornado
pipenv install --dev flake8 flake8-import-order mypy tox ipython

# notice the following command will fail as we haven't installed
# anything into the python3 version 3.7.3 that was installed when
# we installed pipenv...

# instead you can use pipenv's `run` subcommand to use Python 3.7.1
pipenv run python --version
pipenv run ipython

# pipenv's `shell` subcommand is an alternative to `pipenv run <command>`
# it'll drop you into a new shell which uses the relevant Python version
pipenv shell

# now these commands will work as they'll be using 3.7.1
python --version

If you don’t have your ~/.bashrc setup with eval "$(pyenv init -)", then you won’t have /Users/integralist/.pyenv/shims prefixed to your $PATH and so pipenv won’t be able to locate your installed Python versions.

If you don’t want to modify your $PATH then you can manually specify the location of the Python interpreter version you want to use:

pipenv --python /Users/integralist/.pyenv/versions/3.7.1/bin/python

Note: virtual environments (and their .project files can be found here: /Users/integralist/.local/share/virtualenvs).

If you have problems installing a Python version then you might need to reinstall XCode. The following is one solution that works for macOS Mojave:

xcode-select --install
sudo installer -pkg /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg -target /

Note: it’s also useful to set-up autocompletion for pipenv in your .bashrc configuration file eval "$(pipenv --completion)".


Poetry is better in that it’s a cleaner and more isolated installation process (unlike Pipenv which requires us to brew install python3)

# install
curl -sSL | python

# reload .bash_profile and check poetry version
poetry --version

# update poetry to latest version
poetry self:update

# generate auto-complete for Homebrew installed version of bash
poetry completions bash > $(brew --prefix)/etc/bash_completion.d/poetry.bash-completion

# install python version
pyenv install 2.7.15

# check help for poetry init (which generates a `pyproject.toml`)
# poetry doesn't allow installing packages via cli (they need to be specified in toml)
poetry init -h

# create pyproject.toml interactively (see below for generated `pyproject.toml`)
# notice [tool.poetry.dependencies] specifies the Python version used (this is required!).
poetry init

# install dependencies
poetry install

# add additional dependencies (use --dev for dev dependency)
poetry add requests <...>
poetry add --dev requests <...>

# execute commands within the virtual environment (e.g. dev dependency ipython was installed)
poetry run ipython

# load virtual environment permanently for the current shell (e.g. now python version will be the expected environment, not the OS version)
poetry shell
python --version

# here is a shortened Python3 example, as the above uses the OS default of Python2 for installing `2.7.15`
# where as if you tried to set the Python version in the `pyproject.toml` to `^3.7` it would fail as that Python version wouldn't be available
# it means whenever you want to setup a new Python3 environment, you'll need a compatible Python interpreter running first.
# e.g. if you want to install 3.7.1 you'll need 3.7.3 running first to execute Poetry (this isn't necessary with Python2 as we already had 2.7 available by the OS)
pyenv install 3.7.3
pyenv local 3.7.3
poetry add boto3 pytest structlog tornado
poetry add --dev flake8 flake8-import-order mypy tox ipython

Here is an example configuration file I use:

name = "3.7.3"
version = "0.1.0"
description = ""
authors = ["Integralist"]

python = "^3.7"
boto3 = "^1.9"
pytest = "^4.4"
structlog = "^19.1"
tornado = "^6.0"

black = { python=">3.6", version=">=19.3b0", allow_prereleases=true}
flake8 = "^3.7"
flake8-import-order = "^0.18.1"
mypy = "^0.701.0"
tox = "^3.9"
ipython = "^7.5"

requires = ["poetry>=0.12"]
build-backend = "poetry.masonry.api"


This tool is a plugin for pyenv and is designed to manage virtual environments only, where as pipenv and poetry are toolkits designed for solving many different problems (one of which is virtual environments).

You install the plugin via Homebrew:

brew install pyenv-virtualenv

Next you add the following lines to your ~/.bashrc:

eval "$(pyenv init -)"
eval "$(pyenv virtualenv-init -)"

Now within some directory you can define a new virtual environment using:

pyenv virtualenv 3.7.1 testing-plugin-with-3.7.1

To see the available virtual environments:

$ pyenv virtualenvs

3.7.1/envs/testing-plugin-with-3.7.1 (created from /Users/integralist/.pyenv/versions/3.7.1)
testing-plugin-with-3.7.1 (created from /Users/integralist/.pyenv/versions/3.7.1)

To activate and deactivate the virtual environment:

pyenv activate testing-plugin-with-3.7.1
pyenv deactivate


Python Packages

Here are some packages I like to install as a general rule…


You can either install more recent version of vim via Homebrew:

brew install vim

Or you can manually compile vim yourself:

Note: I manually compile vim as I need Python3 support baked in, which Homebrew’s version no longer does (it used to, but not any more). Python3 support means my Python linting tools will work as expected.

git clone

cd vim

./configure --with-features=huge \
            --enable-multibyte \
            --enable-rubyinterp=yes \
            --enable-python3interp=yes \  # relies on `brew install python3`
            --enable-perlinterp=yes \
            --enable-luainterp=yes \
            --enable-gui=gtk2 \
            --enable-cscope \
make && make install

The above code will copy the compiled vim binary into /usr/local/bin so which vim will show /usr/local/bin/vim

Configure vim with vim-plug plugin manager:

curl -fLo ~/.vim/autoload/plug.vim --create-dirs
curl -LSso ~/.vimrc

Ensure Vim is configured with spell checking options:

vim -E -s <<EOF
:set spell

Install plugins by opening vim and executing:


Note: fzf doesn’t need a brew install when installed via vim. See my .vimrc configuration file for more details, but in essence it contains: Plug 'junegunn/fzf', { 'dir': '~/.fzf', 'do': './install --all' }

Also ensure the Golang environment has what it needs by executing:



Install tmux:

brew install tmux

Configure tmux and expose tmuxy command (defined in my ~/.bashrc for quickly spinning up a new working environment):

curl -LSso ~/.tmux.conf
curl -LSso ~/

Note: check $PATH to make sure tmux isn’t double setting values in your PATH as it starts up. If it does you can check an older version of my ~/.bash_profile for a work-around.


Not every app can be installed via Homebrew. Monosnap is one such example.

Also, if you’re into torrents, then npm install -g t-get might be of interest to you.


It can be cool to configure the macOS via the terminal, things like mouse cursor speed or keyboard repeat key performance. But unfortunately that all changed with macOS Mojave and I couldn’t be bothered to figure out the correct way to do it via the terminal when doing the setup via the GUI is just as quick (and I know the few things I like to tweak off-by-heart).

For example, you used to be able to do things like:

defaults write NSGlobalDomain ApplePressAndHoldEnabled -bool false

But since macOS Mojave those settings and namespaces seem to have changed. If you’re interested in figuring it out, then I’d recommend starting with:

defaults read

The above command will display all the current macOS settings for you. From there you can drill down into individual namespaces like so:

defaults read "Apple Global Domain"

Note: here are the settings I used to configure via the terminal.

One thing I like to do is to make sure macOS’ “Spaces” feature doesn’t rearrange spaces based on their recent usage, and to do that you need to open up the ‘Mission Control’ settings panel and disable the option:

Automatically rearrange Spaces based on most recent use

Homebrew Output

Finally, for those interested, below is the output of installing Homebrew for the first time. I like to see what Homebrew creates, so in future if I ever want to know where something should exist I can refer back to this as a reference point:
