One for x86_64, one for arm64.
x86_64 go into /usr/local:
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
This might change when arm64 is supported by default, but this script has this section:
# On macOS, this script installs to /usr/local only.
# On Linux, it installs to /home/linuxbrew/.linuxbrew if you have sudo access
# and ~/.linuxbrew otherwise.
# To install elsewhere (which is unsupported)
# you can untar https://github.com/Homebrew/brew/tarball/master
# anywhere you like.
if [[ -z "${HOMEBREW_ON_LINUX-}" ]]; then
HOMEBREW_PREFIX="/usr/local"
HOMEBREW_REPOSITORY="/usr/local/Homebrew"
HOMEBREW_CACHE="${HOME}/Library/Caches/Homebrew"
# ...
Running this will also update the PATH variable so that /usr/local/bin/brew is in there.
You'll then need to prefix every brew install xxx with arch -x86_64
If you want to install arm64 formulae in parallel, run:
curl -L https://github.com/Homebrew/brew/tarball/master | tar xz --strip 1 -C homebrew in /opt, and use /opt/homebrew/bin/brew, if you don't want to add /opt/homebrew/bin in your PATH for now, which would probably create some conflict with the ones in /usr/local/
