Mac Sequoia setup

I do copy some things over from my previous computer, but it's pretty minimal. Here's the command to gather up what I need to transfer.

tar --exclude '.gnupg/S.*' -cf dotfiles.tar .aws .gitconfig .gnupg .netrc .pypirc .saml2aws .ssh

It's also handy to know all of the projects I'm working on:

cd ~/src
for dname in */.git; do git -C $(dirname $dname) remote -v; done > ~/remotes.txt

The first thing I did this time around was to perform a system software update to get all of that waiting out of the way.

Also takes a while. This can be done from the command line:

xcode-select --install

Still a one-liner, now bash rather than ruby:

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
brew doctor

Homebrew is installed to /opt/local on an Apple Silicon Mac. I add the path in my zsh profile like this:

if [[ -d /opt/homebrew ]]; then
    eval "$(/opt/homebrew/bin/brew shellenv)"
fi

zsh is the default shell on MacOS.

Install my dotfiles.

cd ~
git clone git@github.com:nhoffman/dotfiles.git
dotfiles/mac/bin/install_dotfiles.zsh

I install emacs using https://emacsformacosx.com

Install my emacs configuration:

cd ~
git clone git@github.com:nhoffman/emacs-config.git .emacs.d

Run setup scripts (come back and do this after python is set up):

cd ~/.emacs.d
bin/python-setup.sh

brew install --cask iterm2

Install using homebrew above. Update a few settings.

Settings –> Profiles –> Keys and do these things:

• General: select "Left/right option key acts as": +Esc
• Key Bindings: + –> Keyboard shortcut "OPT+<left arrow>": Send Escape sequence "b"
• Key Bindings: + –> Keyboard shortcut "OPT+<right arrow>": Send Escape sequence "f"

(may have to delete or replace an existing mapping)

Default appearance (I use 15 point on a 15" monitor, 14 on a 13"):

• Settings –> Profiles –> Colors –> Color Presets –> Light Background
• Settings –> Profiles –> Text –> Change Font –> 15 point

Tabs on left:

• Settings –> Appearance –> Tab Bar Location –> Left

Install shell integration:

curl -L https://iterm2.com/shell_integration/install_shell_integration.sh | bash

• Install python runtime by selecting "Scripts" –> "Manage" –> "Install Python Runtime".
• Enable the Python API under "Settings" –> "General" –> "Magic"

I avoid using the system python for anything, and I'm all in on uv. It can be installed using homebrew, but I've settled on using the standalone installer to take advantage of the self update.

curl -LsSf https://astral.sh/uv/install.sh | env INSTALLER_NO_MODIFY_PATH=1 sh
uv python install 3.13
uv python pin 3.13

The path for uv and installed tools is managed in my dotfiles. Here's the relevant excerpt:

# assumes installation using `brew install uv`

if [[ -d "$HOME/.local/share/uv" ]]; then
    export UV_VENV_HOME="$HOME/.local/share/uv/venv"
    export UV_PYTHON_PREFERENCE=only-managed

    # pinned version stored in ~/.python-version
    local python_version=3.13
    local python_pinned="$(uv python pin 2> /dev/null)"
    if [[ -z $python_pinned ]]; then
	uv python pin "$python_version"
    elif [[ "$python_pinned" != "$python_version" ]]; then
	echo "desired python version is $python_version but $(uv python pin) is pinned"
    fi

    mkdir -p "$UV_VENV_HOME"

    mkvenv(){
	local pth=$1
	if [[ -n $VIRTUAL_ENV ]]; then
	    deactivate
	fi

	if [[ -z "$pth" ]]; then
	    uv venv && source ".venv/bin/activate"
	else
	    uv venv "$pth" && source "$pth/bin/activate"
	fi
    }

    select-env(){
	fd -I --hidden -p -d 3 --regex 'bin/activate$' "${1-.}" | \
	    awk -F'/' '{print $(NF-2) ":" $0}' | \
	    fzf --delimiter=":" --with-nth=1 --preview="echo {}" | \
	    cut -d':' -f 2-
    }

    venv(){
	local target="$(select-env .)"
	if [[ -f "$target" ]]; then
	    echo "$target"
	    source "$target"
	fi
    }
fi

Installed the arm64 package from https://cran.r-project.org/bin/macosx/

Some packages that I know I'll need:

R --slave << EOF
packages <- c("lattice", "RSQLite", "latticeExtra", "argparse", "data.table", "tidyverse")
install.packages(packages, repos="https://ftp.osuosl.org/pub/cran/", dependencies=TRUE, clean=TRUE, Ncpus=4)
EOF

Also:

brew install --cask rstudio

Install from https://postgresapp.com/downloads.html

This installs multiple versions of postgres. My zsh profiile includes the path to the CLI for the latest version, eg:

PATH="/Applications/Postgres.app/Contents/Versions/latest/bin:$PATH"

Use Homebrew.

brew install --cask docker
