macOS setup for data science

Here, I summarise how I setup my macOS for the purpose of Data Science. Ultimately, I should invest some time into automating the process.

Install Command Line Developer Tools

xcode-select --install

Install HomeBrew

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

Turn off analytic (optional)

brew analytics off

Install iTerm

brew install iterm

Configure iTerm

To download different colour schemes, visit iTerm Themes

Install Go2Sehll

Download and install from Go2Shell, then configure it to work with iTerm:

Install git

brew install git

Configure git

git config --global user.name "userName"
git config --global user.email "email@mailprovider.com"
git config --global core.excludesfile '~/.gitignore'

Configure ssh key

mkdir ~/.ssh #if it does not already exist
chmod 700 ~/.ssh
cd ~/.ssh
ssh-keygen -t rsa -C "email@mailprovider.com"
enter a keyname
enter a passphrase
cat ~/.ssh/keyname.pub

Copy the key to GitHub. Go to GitHub Settings. From the left margin, choose SSH and GPG keys and click on New SSH key. Paste the value copied above and give the key a name.

eval `ssh-agent -s` # if needed
ssh-add ~/.ssh/KEYNAME

Install zsh

brew install zsh
echo "$(which zsh)"
sudo vi /etc/shells

Edit /etc/shells/ and add the path /usr/local/bin/zsh at the end of the file.

chsh -s $(which zsh)

Install prezto

git clone --recursive https://github.com/sorin-ionescu/prezto.git "${ZDOTDIR:-$HOME}/.zprezto"

Configure prezto

Create soft links ln -s to all the files found in ~/.zprezto/runcoms/ and change each link’s NAME to .NAME:

cd ~
ln -s .zprezto/runcoms/z* .
mv zlogin .zlogin
mv zlogout .zlogout
mv zpreztorc .zpreztorc
mv zprofile .zprofile
mv zshenv .zshenv
mv zshrc .zshrc

Prezto has many useful modules and here is a list of all modules available. You can edit .zpreztorc to enable any of them:

# Set the Prezto modules to load (browse modules).
# The order matters.
