Notes for ARM

_Notes for M1 Mac.md

Notes for OSX on ARM M1 Macs

Here are some notes I am keeping on how I set up a development environment on my M1 mac.

Note: All of these should not be necessary anymore!

Rosetta

softwareupdate --install-rosetta

Rosetta homebrew

arch -x86_64 /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"

Native Homebrew

cd /opt
sudo mkdir homebrew
sudo chown $USER: homebrew
git clone https://github.com/Homebrew/brew homebrew
cd homebrew

./brew install ....

Go (golang)

git clone https://github.com/golang/go
cd go/src
GOOS=darwin GOARCH=arm64 GODEBUG=asyncpreemptoff=1 ./bootstrap.bash -v

If you don't use GODEBUG=asyncpreemptoff=1, you will get hanging background processes eating up your cores. Make sure to keep an eye on activity monitor, and pkill any processes that spin on 100% CPU.

Now that we have a bootstrap, we can build a real toolchain using these commands: (Thanks @cherrymui for the hint)

GOROOT_BOOTSTRAP=$(pwd)/../../go-darwin-arm64-bootstrap ./make.bash

Your native go installation will have its GOROOT at ../. The binaries will be in ../src/ Put it in your path, or copy it somewhere you like.

Rust

Install rustup with homebrew.

/opt/homebrew/bin/brew install rustup-init
rustup update beta

Alacritty

Since alacritty/alacritty#4530 is resolved, we can simply build the latest version from source!

git clone https://github.com/alacritty/alacritty 

cd alacritty
make app

rm -rf /Applications/Alacritty.app || :
cp -r target/release/osx/Alacritty.app /Applications/
