Homebrew

Homebrew is a package manager: it's a software used to install other software from the command line.

Open a terminal and run the following command

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

Set options for Homebrew

export HOMEBREW_CASK_OPTS="--appdir=~/Applications --fontdir=/Library/Fonts"
export HOMEBREW_NO_ANALYTICS=1

Mas

Mas is a command line interface for the App Store.

brew install mas

Fonts

Shell

Since Catalina, macOS comes with ZSH.

I use OMZ.

Installation

sh -c "$(curl -fsSL https://raw.github.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"

In your $HOME, you should have the folder ".oh-my-zsh".

Theme

Iterm2

Iterm2 is a terminal emulator for macOS.

brew install --cask iterm2

Theme

• Material Colors

In iTerm2 Preferences, under Profiles and Colors, go to Color Presets... > Import...

Now open Color Presets... again and select Material Colors to activate the theme.

Git

macOS* comes with a pre-installed version of Git but we'll install our own via Homebrew and not interfere with the system version.

brew install git

Define your git user in .gitconfig

git config --global user.name "Your Name"
git config --global user.email "[e-mail]"

SSH

Generate SSH keys

ssh-keygen -t ed25519 -C "[e-mail]" -f ~/.ssh/<personal_key>

ED25519 are recommended for security and performance, but RSA with a sufficient length is also a valid alternative:

ssh-keygen -t rsa -b 4096 -C "[e-mail]" -f ~/.ssh/<personal_key>

Add a passphrase

Next, you will be prompted to add an (optional) passphrase. We recommend you do so because it adds an extra layer of security: if someone gains access to your computer, your keys will be compromised unless they are attached to a passphrase.

To update a passphrase:

ssh-keygen -p -f ~/.ssh/<personnal_key>

Tell SSH agent

eval "$(ssh-agent -s)" && ssh-add -K ~/.ssh/<personal_key>

Edit SSH config

Example with Github

Host github.com
    HostName github.com
    IdentityFile ~/.ssh/<personal_key>

Copy SSH public key

tr -d '\n' < ~/.ssh/<created_key>.pub | pbcopy

Fix: The authenticity of host github.com (or gitlab) can't be established.

Error

The authenticity of host 'github.com (140.82.113.4)' can't be established.

Fix

ssh-keyscan -t ed25519 github.com >> ~/.ssh/known_hosts

Visual Studio Code

Installation

brew install visual-studio-code

Node.js

Let's install n, a version manager for Node.js.

brew install n

Then install the latest version of node

n lts

Don't forget to set the PATH variable

export PATH="${N_PREFIX}/bin:$PATH"
