Mac

How I setup a new Mac. Adapted from Carlos Alexandro Becker.

1. Install brew

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"
# This will install Command Line Tools if not already present

2. Install deps

git clone https://github.com/emroch/macOS.git ~/.macOS
cd ~/.macOS
# edit Brewfile to remove/add things
brew bundle

If installing apps from the Mac App Store, the installation will fail if not signed into an Apple ID in the store. Running brew bundle again after signing in will complete the installation.

3. Install dotfiles

Managed dotfiles reside in this repo.

git clone https://github.com/emroch/dotfiles.git ~/.dotfiles
cd ~/.dotfiles
./script/bootstrap
zsh
# optional - may be required to properly configure some features (like vim)
dot_update

Zsh may complain about directory permissions being incorrect. Simply run the following to correct it:

compaudit | xargs chmod g-w,o-w

It is also likely that the necessary fonts are not installed for the powerlevel10k theme. From iTerm2, run p10k configure and select "Yes/Y" to install the recommended font.

4. Reasonable defaults

Configure some reasonable default settings using defaults write and pmset.

~/.macOS/set-defaults.sh

5. Setup SSH keys

1Password now supports storing SSH keys, so managing shared keys is very easy.

First, create a new SSH key to be the new Mac's identity. Name this key such that the hostname and key type are clear (ie host_ed25519).

ssh-keygen -t ed25519 -C "user@host"

Optionally, import the machine-specific key to 1Password. This will make it easy to add the public key to other hosts, but is not required.

Also set up 1Password's SSH agent to provide access to the personal id_25519 key.

1. Turn on the 1Password SSH Agent
2. Configure your SSH or Git client

6. Setup Git commit signing

1Password can also serve as a GPG signing agent using a particular SSH key.

Configure Git commit signing with SSH

7. Reboot

Some steps of this setup may require a reboot to take full effect.

sudo reboot

8. Profit!
