MacBook M1 Dev Machine Setup

If you are a Developer and trying to setup your new MAC M1 machine, then this post can help you to get started with the Dev Machine setup.

MAC-M1

1. Rosetta 2

Rosetta 2 is an x86–64 compatibility layer developed by Apple so you can install and run apps that haven’t been ported to ARM yet.

Run the following command on terminal.

/usr/sbin/softwareupdate --install-rosetta --agree-to-license on the terminal

2. Xcode Command Line Tools

These are the tools for software developers that run on the command line, that is, in the Terminal application (also called the console). These tools have been used for programming on Unix operating systems since long.
Run the following command on terminal.
```
xcode-select --install 
```

3. Homebrew

Homebrew (brew) is a free and open-source package manager that allows installation of apps and software in macOS.

Run the following command on terminal to install homebrew.

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

Once homebrew is installed, make sure to setup this PATH in .zshrc or bash_profile file. This step is specifically for MAC M1 and order also matters otherwise brew doctor command will give warnings.
Once this is done you can run this below command to verify if your system is ready to use brew.
```
brew doctor
```
```
echo $HOMEBREW_PREFIX
```

4. Zsh & Ohmyzsh

ZSH, also called the Z shell, is an extended version of the Bourne Shell (sh), with plenty of new features, and support for plugins and themes.
```
brew install zsh && sh -c "$(curl -fsSL https://raw.githubusercontent.com/robbyrussell/oh-my-zsh/master/tools/install.sh)"
```

These are the additional plugins that I installed in my Zsh

For Syntax Highlighting

git clone https://github.com/zsh-users/zsh-syntax-highlighting.git ${ZSH_CUSTOM:-~/.oh-my-zsh/custom}/plugins/zsh-syntax-highlighting

For Zsh Autosuggestions

git clone https://github.com/zsh-users/zsh-autosuggestions ~/.zsh/zsh-autosuggestions

5. Git

Git is a free and open source distributed version control system (DevOps Tool) used for Source Code Management.
```
brew install git 
```
Once git is installed then you can check the version by running command “git –version”.
How to setup multiple Git Accounts ?
Your Mac has a SSH config file in a .ssh directory. The config file is where you establish relationships of your SSH keys to each GitHub (or Bitbucket) account, and all your SSH keys generated are saved into .ssh directory by default.
1. Creating the SSH keys:
```
ssh-keygen -t rsa -b 4096 -C "your_email@example.com"     
```
2. Register your keys to respective Github accounts. Follow these steps to do so.
3. Go to SSH config file at ~/.ssh and amend accordingly to:
```
#personal github user1-account
Host github.com
HostName github.com
User git
IdentityFile ~/.ssh/id_rsa
IdentitiesOnly yes
          
#github.abc.com user2-account
Host github.com
HostName github.com
User git
IdentityFile ~/.ssh/jd_git_id_rsa
IdentitiesOnly yes
```
4. Go ahead to git clone your respective repository.
5. Open up local git config using git config –local -e and add:
```
[user]
     name = user1
     email = user1@gmail.com
```
6. Run git config –list to view git configurations.

6. IntelliJ

IntelliJ IDEA is the professional IDE that enables enterprise and full-stack application development & JVM development.
```
brew install --cask intellij-idea
```

7. Colima

I found Colima to be a great drop-in replacement for Docker Desktop. If you need to run containers on your Mac, Colima is an open-source container runtime with minimal setup that works on MacOS and Linux.
If you already have Docker installed on your MAC then you can run these commands to cleanup and uninstall Docker Desktop app.
```
brew uninstall --cask docker
rm -rf ~/.dockercfg
```

Now since you have installed brew then using brew you can setup Colima on your MAC in the fastest way.

Install Colima
```
brew install Colima 
```

Once Colima is installed then install Docker

brew install Docker
brew install docker-credential-helper

Now install Docker Compose

mkdir -p ~/.docker/cli-plugins
curl -SL https://github.com/docker/compose/releases/download/v2.2.3/docker-compose-darwin-aarch64 -o ~/.docker/cli-plugins/docker-compose
chmod +x ~/.docker/cli-plugins/docker-compose

Now start the colima
```
colima start
```

To verify the installation

docker compose Version

docker run hello-world

Now if you face this issue and unable to pull the hello-world image. Error Like :

Error response from daemon: Get "https://registry-1.docker.io/v2/": dial tcp:  
lookup registry-1.docker.io on 192.168.5.3:53: read udp 192.168.5.15:51522->192.168.5.3:53: i/o timeout

Then try starting the colima with specific configurations of amdprofile:

colima start --arch amd --profile amdprofile

Now try pulling the image again by running the command : $ docker run hello-world
