What's inside my macOS?

After completely reinstalling the whole new macOS, you probably want to make everything in a great order.

Personal Preference

  1. Create a new Admin user (Temp)
  2. Login with the new Admin user

  4. Go to Users & Groups
    • Change Account name from jay to Jay
    • Change Home directory from /Users/jay to /Users/Jay
  5. Login with Jay
  6. Delete Temp

Boost Up Workflow

  1. Download Magnet from App Store
  2. Increase cursor speed
defaults write NSGlobalDomain KeyRepeat -int 1
defaults write NSGlobalDomain InitialKeyRepeat -int 20
  1. Set the password less than 4 characters

Setup Homebrew and Terminal

We use Homebrew since it’s a great package manager.

  1. Install Homebrew

    /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
    
  2. Install iTerm2 + zimfw

    # Install iTerm2 via Homebrew!
    brew install --cask iterm2
    
    # Install zimfw
    curl -fsSL https://raw.githubusercontent.com/zimfw/install/master/install.zsh | zsh
    
    # Add powerlevel10k
    echo 'zmodule romkatv/powerlevel10k' >> ~/.zimrc
    
    # Install powerlevel10k
    zimfw install
    # Now, `powerlevel10k` folder appears in `/Users/Jay/.zim/modules`
    
    # In /Users/Jay/.p10k.zsh
    # Change
    #     `typeset -g POWERLEVEL9K_VCS_BRANCH_ICON=`
    # to
    #     `typeset -g POWERLEVEL9K_VCS_BRANCH_ICON='\uF126 '`
    
  3. Resolve VSCode Powerline problem

    • Add Nerd Font

      # Search the font that supports `powerlevel10k`
      brew install nerd
      brew install --cask homebrew/cask-fonts/font-sauce-code-pro-nerd-font
      
      # Change the font in iTerm/Terminal
      # Go to iTerm's Preferences
      #             > Profiles
      #             > Text
      # Choose "SauceCodePro Nerd Font Mono"
      
      # Change the font to 18 (be good to your eyes)
      
    • Add "terminal.integrated.fontFamily": "monospace, 'SauceCodePro Nerd Font Mono'" in settings.json

Show/Hide path in the Finder title bar

# Show
defaults write com.apple.finder _FXShowPosixPathInTitle -bool true; killall Finder
# Hide
defaults write com.apple.finder _FXShowPosixPathInTitle -bool false; killall Finder

C++

  • In VSCode > settings.json

    "clang-format.executable": "/usr/local/bin/clang-format",
    "[cpp]": {
        "editor.defaultFormatter": "xaver.clang-format"
    },
    

Java

  • brew install --cask AdoptOpenJDK/openjdk/adoptopenjdk{11,15}

  • In ~/.zshrc:

    # JDK Switch
    export JAVA_11_HOME=`/usr/libexec/java_home -v 11` # 把 Java 11 的路徑位置存到左側變數
    export JAVA_15_HOME=`/usr/libexec/java_home -v 15` # 把 Java 15 的路徑位置存到左側變數
    
    # Default version = Java 11
    export JAVA_HOME=$JAVA_11_HOME
    
    alias jdk11='export JAVA_HOME=$JAVA_11_HOME'
    alias jdk15='export JAVA_HOME=$JAVA_15_HOME'

ln -s $etc/docker.zsh-completion /usr/local/share/zsh/site-functions/_docker

Safari Extension, Xcode

We need safari-web-extension-converter to convert our Chrome Extension. However, out xcode-select doesn’t link to the correct path.

# original
xcode-select -p # /Library/Developer/CommandLineTools

# connect to the correct path
sudo xcode-select -s sudo xcode-select -s /Applications/Xcode.app

# now, we can do the following to convert our app
xcrun safari-web-extension-converter ~/Repositories/leetcode-search-by-question-id

Python Env

# Make sure to install `anaconda` by brew first
brew install --cask anaconda

# Init `conda` because we don't have this command in `macOS`
cd /usr/local/anaconda3/bin

# Init zsh configuration
./conda init zsh
# Restart the terminal, the conda configuration is now in ~/.zshrc

# Choose one
## Turn off conda default env
conda config --set auto_activate_base false
## Turn on conda default env
conda config --set auto_activate_base true
# e.g.
# Create an env for Mkdocs deployment
conda create --name MKDOCS python=3.8

# Activate this environment
conda activate MKDOCS

# Now work with this cute MKDOCS env!
pip install mkdocs
pip install mkdocs-material

# Happy deploying!
# Remove <ENV NAME>
conda remove --name <ENV NAME> --all

# Deactivate the current environment
conda deactivate

Node Env

Ref

brew install nvm

Add the following in your ~/.zshrc

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

You many see this message:

zsh compinit: insecure directories, run compaudit for list.
Ignore insecure directories and continue [y] or abort compinit [n]?

Security: For security reasons compinit also checks if the completion system would use files not owned by root or by the current user, or files in directories that are world- or group-writable or that are not owned by root or by the current user. If such files or directories are found, compinit will ask if the completion system should really be used. To avoid these tests and make all files found be used without asking, use the option -u, and to make compinit silently ignore all insecure files and directories use the option -i. This security check is skipped entirely when the -C option is given.

compaudit | xargs chmod g-w
nvm use system
nvm run system --version
nvm install 14.15.3
nvm install 15.5.0

Vim/Neovim

# install neovim
brew install neovim

# install vim-plug under neovim
sh -c 'curl -fLo "${XDG_DATA_HOME:-$HOME/.local/share}"/nvim/site/autoload/plug.vim --create-dirs \
       https://raw.githubusercontent.com/junegunn/vim-plug/master/plug.vim'

The Neovim config file is located in ~/.config/nvim/init.vim.

mkdir -p ~/.config/nvim
touch ~/.config/nvim/init.vim
nvim ~/.config/nvim/init.vim

Paste the following code in ~/.config/nvim/init.vim.

It allows you to configure plugins by adding references to their GitHub repositories:

call plug#begin('~/.vim/plugged')

" [Plugin section]
Plug 'dracula/vim'

call plug#end()

" [Config section]
if (has("termguicolors"))
  set termguicolors
endif
syntax enable
colorscheme dracula

Install the plugin and reload the editor to have an effect.

nvim +PlugInstall

Git

  1. Set up commit information

    • Globally

      # set the gitconfig
      git config --global user.name 'Jay Chen'
      git config --global user.email 'walkccray@gmail.com'
      
      # check the gitconfig
      cat ~/.gitconfig
      # [user]
      #         name = Jay Chen
      #         email = walkccray@gmail.com
      
    • Locally (in the Git repository):

      git config -l
      git config user.name 'Jay Chen'
      git config user.email 'walkccray@gmail.com'
      
  2. Revert a Git repository to a previous commit

  3. Rebase without changing timestamps

git rebase -i --root
# Change the commit from "pick" to "edit"
# :wq
GIT_COMMITTER_DATE="2018-03-20T12:00:00" git commit --amend --date="2018-03-20T12:00:00"
# Check the SHA of the new root commit message
git rebase --committer-date-is-author-date SHA_OF_ROOT
