Mac M2 Sonoma 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

The new iOS-style System Settings takes a bit of getting used to.

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 M1 Mac. This required updating my PATH configuration. I added the following to my login profile:

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

The new location required a number of changes to various login steps configuring homebrew-installed components.

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 Mappings: + –> Keyboard shortcut "OPT+<left arrow>": Send Escape sequence "b"
• Key Mappings: + –> Keyboard shortcut "OPT+<right arrow>": Send Escape sequence "f"

(may have to delete or replace an existing mapping)

Default appearance:

• Settings –> Profiles –> Colors –> Color Presets –> Light Background
• Settings –> Profiles –> Text –> Change Font –> 14 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 "Preferences" –> "General" –> "Magic"

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

Sonoma ships with Python 3.9.6 as /usr/bin/python3 with no python executable (or maybe it's installed with xcode tools - I forgot to check). I avoid using the system python for the most part.

Since I moved off of Intel macs, I have been using the Homebrew emacs-plus project, which seems great so far.

brew install libressl
brew install aspell
brew install gpg
brew tap d12frosted/emacs-plus
brew install emacs-plus

Edit: after emacs 39.1 came out, I updated with:

brew uninstall emacs-plus
brew install emacs-plus@29 --with-imagemagick --with-native-comp

Check out my .emacs.d and run setup scripts.

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

Run setup scripts:

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

The main inconvenience was having to adapt my startup script to juggle M1 Mac, x86 Mac, and linux. Here's the relevant portion.

if [[ $(uname) == 'Darwin' ]]; then
    if [[ $(uname -m) == 'arm64' ]]; then
	# assume we are using emacs-plus
	EMACS=/opt/homebrew/bin/emacs
	EMACS_BIN=/opt/homebrew/bin/emacsclient
    else
	EMACS=/Applications/Emacs.app/Contents/MacOS/Emacs
	EMACS_BIN=/Applications/Emacs.app/Contents/MacOS/bin
    fi
    alias emacs="$EMACS"
    # provides emacsclient
    export PATH=$EMACS_BIN:$PATH
else
    EMACS=$(readlink -f emacs)
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="http://cran.fhcrc.org/", 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
