Using Homebrew on Apple Silicon (M1) Macs

Currently running Homebrew natively on Apple Silicon is an “unsupported” configuration, so you’ll have to jump through a few hoops:

• Install Homebrew to /opt/homebrew manually:

  $ sudo mkdir /opt/homebrew
  $ sudo chown -R $(whoami):admin /opt/homebrew
  $ cd /opt
  $ curl -L https://github.com/Homebrew/brew/tarball/master | tar xz --strip 1 -C homebrew
  

• Add /opt/homebrew/bin to your path, before /usr/local/bin
• (Optional, though recommended) Install Intel-flavored Homebrew to /usr/local/bin:

  $ arch -x86_64 /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"
  $ alias ibrew='arch -x86_64 /usr/local/bin/brew'
  

Now, when you run brew it will invoke the arm64 version and build/install arm64 binaries and libraries to /opt/homebrew, and when you run ibrew it will invoke the the x86_64 version and build/install x86_64 binaries and libraries to /usr/local.
