Command Line Interface (CLI)⚓︎

Rosetta 2⚓︎

Rosetta 2 is Apple's utility to translate Intel-based (x86) apps, so they're Apple Silicon-compatible. It's no longer bundled with macOS as of Monterey. If I try to open an x86 app, I'll be prompted to install it. Otherwise, I can type in the Terminal

softwareupdate --install-rosetta

Shell⚓︎

zsh is the default shell in macOS as of Catalina.

Changing shells⚓︎

To change shells, do

chsh -s <executable_path>

where <executable_path> is the path to the shell executable. For example, to change to bash, do

chsh -s /bin/bash

If installing a new shell with Homebrew (see above), the executable paths should automatically symlink. So finding the exact path shouldn't be necessary.

If changing the shell, log out and log back in to ensure it takes effect.

Extensions⚓︎

Amazon Q is an decent tool for managing terminal-related stuff: appearance, autocomplete, shell profiles, settings, plugins, etc. It's similar to Oh My Bash/Zsh, but more modern and with a GUI. And it works with bash, zsh, and fish.

Install it with Homebrew (see above). Then, open it and follow the instructions to set it up. It should automatically detect the shell and prompt anything else it needs.

Other things to install:

.zshrc⚓︎

The .zshrc configuration file requires manual editing with Amazon Q, compared to Fig (RIP). Add these lines between the Amazon Q blocks:

# Executables for Homebrew and Pyenv
export PATH="$PATH:/opt/homebrew/bin:/opt/homebrew/sbin:$HOME/.pyenv/bin"

# Activate Pyenv and Python
eval "$(pyenv init --path)"
eval "$(pyenv init -)"

# Activate Google Cloud SDK completions
if [ -f /opt/homebrew/share/google-cloud-sdk/completion.zsh.inc ]; then
    source /opt/homebrew/share/google-cloud-sdk/completion.zsh.inc
fi
if [ -f /opt/homebrew/share/google-cloud-sdk/path.zsh.inc ]; then
    source /opt/homebrew/share/google-cloud-sdk/path.zsh.inc
fi

# Activate Zsh syntax highlighting. Put this at the very end of the file
source /opt/homebrew/share/zsh-syntax-highlighting/zsh-syntax-highlighting.zsh

  • Terminal settings/preferences (personal choice): Ocean_Esh.terminal

    1. Open the Terminal, and go to Preferences Profiles
    2. Hit the three dots in the bottom left corner and click Import...
    3. Select the terminal preferences file and set it as the default

  • Hyper settings:

    hyper i hyper-material-theme
hyper i hyper-fading-scrollbar
hyper i hyper-blink
hyper i hyper-quit
hyper i default-shell

Verified Git commits⚓︎

For that sweet Verified mark next to commits on GitHub, the simplest method is to generate a GPG key and associate it with your account. Start with

gpg --default-new-key-algo rsa4096 --gen-key
# Enter real name
# Enter email address associated with GitHub account
# Don't enter a passphrase unless you want to type it in every time you commit
# Enter `o` to finish

Then view the key with

gpg --list-secret-keys --keyid-format=long

The output will look something like

gpg: checking the trustdb
gpg: marginals needed: 3  completes needed: 1  trust model: pgp
gpg: depth: 0  valid:   1  signed:   0  trust: 0-, 0q, 0n, 0m, 0f, 1u
gpg: next trustdb check due at 2024-12-01
/Users/username/.gnupg/pubring.kbx
--------------------------------
sec   rsa4096/ABC123DEF456GHI 2022-12-02 [SC] [expires: 2024-12-01]
      JBNM4H5LJK5BKJ4BMNVTBHOI4H55P4BJ5K6L4JKL
uid                 [ultimate] Real Name <username@domain.com>

The bit after sec rsa4096/ is what we need next (ABC123DEF456GHI). To show the public key, do

gpg --armor --export ABC123DEF456GHI

which will output something like

-----BEGIN PGP PUBLIC KEY BLOCK-----

AMASSIVEBLOCKOFLETTERSNUMBERSANDSYMBOLS
-----END PGP PUBLIC KEY BLOCK-----

Remove existing keys and associate this one to your GitHub account with

git config --global --unset gpg.format
git config --global user.signingkey ABC123DEF456GHI
git config --global commit.gpgsign true

Then copy that public key we generated earlier (in its entirety), and add it to your GitHub account:

  1. Visit https://github.com/settings/gpg/new
  2. Add a title
  3. Paste the public key
  4. Hit Add GPG key

This should apply to GitHub Desktop as well, not just commits on the CLI. Just ensure you're using the same email address for your commits as entered when creating the key. Double check in Preferences Git Email.
