Development Setup in Apple Silicon

Command Line Tools for Xcode and Rosetta2

# Rosetta2
❯ softwareupdate --install-rosetta  --agree-to-license
# Command Line Tools(including python3, clang and other useful libraries)
❯ xcode-select --install

Zsh and Oh-My-Zsh

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

Notable Themes:

powerlevel10k is an awesome-looking theme for Zsh which can actually make your shell faster!

Configuring ~/.zshrc:

alias leg="arch -x86_64 zsh" # alias enter Rosetta terminal

Or if using many Alias and PATH setting, it's better to put them into a ~/.profile file, and add it to ~/.zshrc:

# before `~/.p10k.zsh`
[[ ! -f ~/.profile ]] || source ~/.profile

[[ ! -f ~/.p10k.zsh ]] || source ~/.p10k.zsh

add cpu_arch into POWERLEVEL9K_RIGHT_PROMPT_ELEMENTS in ~/.pk10k.zsh to show whether x86 or arm cpu arch in mac m1.

typeset -g POWERLEVEL9K_RIGHT_PROMPT_ELEMENTS=(
    ...
    cpu_arch              # CPU architecture
    ...
)

Homebrew(Both Arm64 and X86_64)

1. Native Homebrew

   ❯ arch --arm64 bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"

   all Homebrew related stuffs are in /opt/homebrew.

2. Rosetta Homebrew

   ❯ arch --x86_64 bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"

   all Homebrew related stuffs are in /opt/local.

To switch between native and intel-emulated Homebrews based on different working architecture, you can add following into ~/.zshrc,

Configuring ~/.zshrc:

if [ "$(arch)" = "arm64" ]; then
    eval "$(/opt/homebrew/bin/brew shellenv)"
else
    eval "$(/usr/local/bin/brew shellenv)"
fi

So, in Rosetta terminal, we will have brew linked to /usr/local/bin/brew,

❯ leg
❯ arch
i386
❯ which brew
/usr/local/bin/brew

Mirrors:

Python3.7, Python3.8, Python3.9

Python3.8 and Python3.9 are natively supported in Applie Silcon,

❯ arch
arm64
❯ brew install python@3.8 python@3.9
❯ file /opt/homebrew/opt/python@3.8/bin/python3
/opt/homebrew/opt/python@3.8/bin/python3: Mach-O 64-bit executable arm64

Python3.7, however and other belows will never be supported on Apple Silicon:

NOTE: There are no plans to backport support to 3.7 and 3.6 which are in the security-fix-only phase of their release cycles.

❯ leg
❯ arch
i386
❯ brew install python@3.7
❯ file /usr/local/opt/python@3.7/bin/python3
/usr/local/opt/python@3.7/bin/python3.7: Mach-O 64-bit executable x86_64

Configure ~/.zshrc:

if [ "$(arch)" = "arm64" ]; then
    eval "$(/opt/homebrew/bin/brew shellenv)"
    export PATH="/opt/homebrew/opt/python@3.8/bin:$PATH"
    export PATH="/opt/homebrew/opt/python@3.9/bin:$PATH"
else
    eval "$(/usr/local/bin/brew shellenv)"
    export PATH="/usr/local/opt/python@3.7/bin:$PATH"
fi

Python packages requiring compilation

# useful Python C-library compliation flags
export LDFLAGS="-L$(brew --prefix openssl)/lib -L$(brew --prefix zlib)/lib"
export CPPFLAGS="-I$(brew --prefix openssl)/include -I$(brew --prefix zlib)/include"

NVM

Native nvm,

❯ arch
arm64
❯ brew install nvm

Configure ~/.zshrc:

export NVM_DIR="$HOME/.nvm"
[ -s "/opt/homebrew/opt/nvm/nvm.sh" ] && . "/opt/homebrew/opt/nvm/nvm.sh"  # This loads nvm
[ -s "/opt/homebrew/opt/nvm/etc/bash_completion.d/nvm" ] && . "/opt/homebrew/opt/nvm/etc/bash_completion.d/nvm"  # This loads nvm bash_completion

.NET

Here is the aim to install both arm64 and x64 respectively.

1. Download .NET from website respectively for arm64 and x64 version, the former will be installed into "/usr/local/share/dotnet" and the later will be in "/usr/local/share/dotnet/x64".

2. Delete the dotnet environment setting PATH, otherwise it will always prepend the arm dotnet path in first.

   ❯ cat /etc/paths.d/dotnet
   /usr/local/share/dotnet
   ❯ rm -rf /etc/paths.d/dotnet

   NOTE: this is because /usr/libexec/path_helper makes the trouble in macOS.

3. Configure ~/.zshrc to use arm64 and x64 dotnet:

   # Multiple Homebrews on Apple Silicon
   if [ "$(arch)" = "arm64" ]; then
       eval "$(/opt/homebrew/bin/brew shellenv)"
       export DOTNET_ROOT="/usr/local/share/dotnet"
       export PATH="$DOTNET_ROOT:~/.dotnet/tools:$PATH"
   else
       eval "$(/usr/local/bin/brew shellenv)"
       export DOTNET_ROOT="/usr/local/share/dotnet/x64"
       export PATH="$DOTNET_ROOT:~/.dotnet/tools:$PATH"
   fi
