Run Homebrew Natively on Apple Silicon Arm M1

Workarounds for ARM-based Apple-Silicon Mac

This is how I get most of my configurations work with MacBook Pro (13, M1, 2020) Tested on macOS Big Sur (11.0.1) Created on Nov 17, 2020 Last update: Nov 18, 2020

Rosetta2

At the time of the writing (Nov 17), most of the applications are not (yet) supported by this new architecture and most of the applications will run with Rosetta2 created by Apple.

The first time you launches a x86-64 application on your mac, it will automatically pop up and ask you to install Rosetta. The process takes about 2 minutes. And then I am able to open those applications as if they are native built for ARM mac.

Rumors said that it takes 20 secs to load Microsoft Word at the first launch for the translation; however, it only takes 6.89 secs to open on my machine, which is as fast as, if not faster, than the loadtime on my 16 inch MacBook Pro. I don't know if it's because it's already translated when I was installing the app or Microsoft/Apple has done some optimization. For other apps, e.g. IINA, that runs with x86, even the first launch is as quick as you would expect on a new machine, most of which are under 5 secs. It's quite impressive.

Xcode build

If choose to use the git provided by xcode, after installing Xcode, you will have to agree with their license

You have not agreed to the Xcode license agreements. You must agree to both license agreements below in order to use Xcode.

Hit the Return key to view the license agreements at '/Applications/Xcode.app/Contents/Resources/English.lproj/License.rtf'

Agreeing to the Xcode/iOS license requires admin privileges, please run “sudo xcodebuild -license” and then retry this command.

Simply use its command, press space to continue and q to exit, and then type agree to agree the license. Then commands like git, make will be available.

Homebrew

Homebrew is not (yet) officially supported on Apple Silicon Macs, and their teams are working on it.
They have provided a detailed list of how core formulaes are supported. You can find that list here.

As there's no official support for this mac at this moment, most of the installations listed below are just my personal workarounds tested on my local machine. There's no guarantee that it's the best practice or it will work on your machine.

Installation

I found this alternative install method on the official documentation of homebrew, which can be found here 　

For ARM-based macs, their recomendation is to "do yourself a favour and install to /opt/homebrew on macOS ARM" One of the easiest way to do that is to untar it to your local directory and then move it to /opt as it requires root permission to write in the /opt folder.

cd ~
mkdir homebrew && curl -L https://github.com/Homebrew/brew/tarball/master | tar xz --strip 1 -C homebrew
sudo mv homebrew /opt/homebrew

This way homebrew will be installed to the /opt/homebrew folder. We can then initiate homebrew by cd to that directory and run brew in the bin folder.

cd /opt/homebrew/bin
./brew update

This operation requires git, and git is not built-in in ARM Big Sur as it did for older macs. If you didn't install xcode beforehand, there will be another pop up that asks you to install command-line tools for developers. Expected outputs (as on my local machine):

After that you can add brew (and the packages managed by brew) to your PATH.

For macOS Big Sur, the default shell is zsh. You can create a .zshrc file in your home directory and add this line to the config.

export PATH="/opt/homebrew/bin:$PATH"

Formula

Brew has not yet provided packages precompiled for arm macs. The best way to install is with the brew install -s <fomula> command. As explained by homebrew, it will "Compile formula from source even if a bottle is provided. Dependencies will still be installed from bottles if they are available." The list of supported packages can be found here

I've successfully compiled several binaries on my local machine, and I will upload the binaries as bottles to save some compile time.

Problems I've encountered: While compiling neovim, I found that the system fails to recogonize my luajit installation and keeps sending me the error: Lua interpreter not found at /opt/homebrew/opt/luajit

I solved this issue by creating a symlink within the /opt/homebrew/opt/luajit/bin folder that redirects lua to luajit,

cd /opt/homebrew/opt/luajit/bin
ln luajit-2.1.0-beta3 lua

However, even after this issue is fixed, I still get the error:

Neovim now builds with this pull request

Seeing that I cannot build neovim, I turned to emacs,

The prebuilt version for x86 cannot be run using Rosetta. It crashes at launchtime,

When I try to compile emacs myself, I failed yet again,

checking for xcrun... xcrun
checking for make... yes
checking for GNU Make... make
checking build system type... arm-apple-darwin20.1.0
checking host system type... arm-apple-darwin20.1.0
configure: error: Emacs does not support 'arm-apple-darwin20.1.0' systems.
If you think it should, please send a report to bug-gnu-emacs@gnu.org.
Check 'etc/MACHINES' for recognized configuration names.

But it did help me to test yet another bunch of packages. Ironically, the emacs.app (emacsformacosx) downloaded from GNU website works, guess I will stick to it before neovim or emacs builds natively.
