This post explains my initial setup on M1 Macbook Air(2020) for development.

It’s my first time using Macbook so some essential steps might be missing.

Development Setup

Here are some things that I find to be essential setups for development.
I didn’t include any programing language installation as I will do those along the way when I need them.

Homebrew

Intall via Terminal

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

Add brew to PATH to enable commands

$ echo 'export PATH=/opt/homebrew/bin:$PATH' >> ~/.zshrc

Not sure if this is necessary but did it anyway

$ source ~/.zshrc

To check if installation has been done correctly and if command works

$ brew --version

Visual Studio Code

$ brew install visual-studio-code

Rosetta2

$ /usr/sbin/softwareupdate --install-rosetta

Git

$ brew install git

Java

Tap from Homebrew

$ brew tap AdoptOpenJDK/openjdk

Look for available versions

$ brew search openjdk

Install version 14

$ brew install adoptopenjdk14

Terminal Setup

Below are the setup needed to make terminal more user friendly and pretty

iTerm

$ brew install --cask iterm2

Choose color from https://iterm2colorschemes.com
Save the color configuration as text with no extension
Go to iTerm2 > Preferences > Profiles > Colors
Import Color Presets(mychoice : Arthur)

Ohmyzsh

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

Powerlevel10k

$ git clone --depth=1 https://github.com/romkatv/powerlevel10k.git ${ZSH_CUSTOM:-$HOME/.oh-my-zsh/custom}/themes/powerlevel10k

By this point, your .zshrc probably was reset.
Run below to add brew back into terminal

$ echo 'export PATH=/opt/homebrew/bin:$PATH' >> ~/.zshrc

Also, turn on VSCode and tap Command + Shift + P,
Type in Install,
Click >Shell Command: Install 'code' command in PATH

In .zshrc Line 11, change as the below,

ZSH_THEME="powerlevel10k/powerlevel10k"

Add below lines to settings.json

"terminal.external.osxExec": "iTerm.app"
"terminal.integrated.fontFamily": "MesloLGS NF"

Github CLI

$ brew install gh
$ gh auth login
$ git config --global user.name "your name"
$ git config --global user.email "your email"
$ git config --global init.defaultBranch main

etc

Google Chrome

$ brew install google-chrome

That was my rough setup for my first Macbook Air :)
Next up is some of useful extensions and setting for Visual Studio Code.
