I recently bought an M1 Macbook Air with 16 GB RAM. Below is a log of how and what I downloaded on my machine for a full stack Clojure development experience.
The M1 is an ARM chip and thus the software which runs on it must be compatible with the ARM instruction set instead of the x86 instruction set.
Fortunately I’ve had no problems moving from Linux/WSL to the M1 full time. There were a few minor hurdles, but nothing has been a deal breaker yet.
The first thing I did was setup my Apple ID. Then I wanted to download my most used apps which I did (without brew):
- Firefox developer edition
- Docker for Mac
- HomeBrew - https://brew.sh
HomeBrew (or simply “brew”) is a package manager for macOS. I haven’t had a great experience dealing with some of the brewisms, but it has a huge repertoire and it just works.
So let’s start brewing
# mpv the best media player brew install —cask mpv brew install --cask keepassxc # save your ℀ brew install --cask flux # save your 👀 brew install --cask maccy # clipboard manager brew install youtube-dl brew install jq wget coreutils shellcheck tree cloc
--cask here? Cask is a way to install GUI application using
In the earlier days I think it was necessary to install x86 binaries in a specially rosseta2 terminal, but I’ve never had to do that.
For example you must have seen people asking you to do this before running brew install on specific software:
/usr/bin/arch -x86_64 zsh
But I’ve never had to do this. I think the newer versions of MacOS automagically detect x86 binaries and run them under rosseta2 without having to do anything at all.
I’ve never once worried about this incomaptibility except for not being able to run certain Docker containers (which is also quite rare).
Java & Clojure
It’s really simple to install JDK, Clojure CLI tools, and leiningen using homebrew.
# java/jdk, we need this for clojure brew install openjdk brew install leiningen brew install maven brew install clojure/tools/clojure
I chose to not install
brew install openjdk@17 explicitly, because leiningen
and maven depend on the latest openjdk so that gets installed anyways. If you
want a specific version like say JDK v11, then you can also do something like
brew install openjdk@11.
Then put the path of openjdk@11 first in your
$PATH var in shell so clojure picks that up.
If the above does not work for you, try running this with sudo perms and see if that works as a fix:
sudo ln -sfn /opt/homebrew/opt/openjdk/libexec/openjdk.jdk /Library/Java/JavaVirtualMachines/openjdk.jdk
Babashka has become such a huge part of my everyday workflow nowadays. So let’s install that ASAP
brew install borkdude/brew/babashka
Node & NPM
I mainly work on Clojurescript with shadow-cljs which only needs node and npm installed.
brew install node@14
I use Iosevka as my choice of font, which is easy to install using brew.
Unfortunately there’s a rendering performance issue with Iosevka on Emacs + MacOS. It was a hard bug to find, but switching to fira-code fixes those performance issues.
brew tap homebrew/cask-fonts brew install —cask font-iosevka brew install —cask font-fira-code
Emacs on mac m1
There are a lot of ways to install emacs on the m1, but I found
to be the best in the sense that it works out of the box and as expected 🙂
brew tap railwaycat/emacsmacport brew install --cask emacs-mac ln -s ~/projects/dotfiles/emacs.d ~/.emacs.d
Then I changed the
CTRL to avoid the emacs pinky and also
because who uses caps lock 😂
Go to System Preferences → Keyboard → Caps and select it as “control modifier”
My choice of emacs configuration layer is Corgi Emacs, it’s a lightweight version of spacemacs/doom aimed at Clojure users. So do give it a try!
A lot of Mac users prefer to use iTerm2, and it has lots of benefits. But this time around I didn’t really find a need for it, so I’m just using the built-in terminal.app
macOS now ships with zsh as the default shell. So the first thing I did was
install oh-my-zsh and link my
sh -c "$(curl -fsSL https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh)" ln -s ~/projects/dotfiles/shell/zshrc ~/.zshrc
Now my zsh config started complaining that it didn’t find tmux. Any terminal
I open launches a tmux instance automatically. This way I almost completely
tmux and the terminal.app works just fine
for that! So let’s install
tmux and some other terminal helper/utilities
brew install tmux brew install tmuxp brew install ripgrep brew install fzf brew install fd brew install direnv
Then I generate an ssh key. Folks remember to use ed25519 algorithm as RSA is now being deprecated.
ssh-keygen -t ed25519
Docker for Mac was installed using their website and it runs as expected. I haven’t had any issues uptil now as most of the images I run are well supported for ARM.
A lot of terraform plugins had to be updated to newer versions which support Darwin ARM builds.
brew install hashicorp/tap/terraform
All in all I am extremely happy with this machine. The battery life is amazing, there is no FAN noise, it never heats up, and software runs and builds much faster than my ~9 year old custom built PC.
One thing I hate is that it only has 2 ports and can only drive a single external monitor. Both of these are minor annoyances for me, but not enough to give up on this laptop.
