Nightly binary builds of Emacs for macOS as a self-contained Emacs.app, with native-compilation.

Features

  • Self-contained Emacs.app application bundle, with no external dependencies, built with the jimeh/build-emacs-for-macos build script.
  • Native-compilation is enabled in nightly builds from the master branch of Emacs, and should just work without the need to install GCC, libgccjit, or any other dependencies.
  • Includes the fix-window-role and system-appearance patches from the excellent emacs-plus project.
  • Emacs source is fetched from the emacs-mirror/emacs GitHub repository.
  • Build creation is transparent and public through the use of GitHub Actions, allowing anyone to inspect git commit SHAs, full source code, and exact commands used to produce a build. This is especially important right now as builds are not yet signed and notarized.

System Requirements

  • Intel-based Mac running macOS 10.15.x or later.

Downloads

See the Releases page to download latest builds.

Nightly builds of Emacs are for the part just fine, but if you don't like living too close to the edge, see issue #7 Known Good Nightly Builds for a list of recent nightly builds which have been actively used by a living being without any issues.

Build Process

Building Emacs is done using the jimeh/build-emacs-for-macos build script, executed within a GitHub Actions workflow. This is why macOS 10.15.x or later is required, as it's the oldest version of macOS available in GitHub Actions.

Full history for all builds is available on GitHub Actions here.

Nightly builds are scheduled for 0:00 UTC every night, based on the latest commit from the master branch of the emacs-mirror/emacs repository. This means a nightly build will only be produced if there have been new commits since the last nightly build.

Untrusted Application

Currently builds are not signed or notarized, meaning macOS cannot verify Emacs.app came from a trusted developer, and by default you are not given an option to trust the app and open it.

Simplest way around this is to right-click (or control-click) on the Emacs app in Finder and select "Open". You will then be given the same warning as before, but with a "Open" button now available to trust and open the app. After that you can open the application like normal without any warnings.

Issues / To-Do

    Emacs builds expecting GCC to be installed

    Since Emacs.2021-06-23.7be75f1.master I get the same message: "Library not loaded: /usr/local/lib/gcc/11/libgcc_s.1.dylib".

    This is required by subr--trampoline on this build and subsequent ones.

  • Cannot find /usr/local/lib/gcc/11/libgcc_s.1.dylib

    Cannot find /usr/local/lib/gcc/11/libgcc_s.1.dylib

    This issue occurred since the *.dmg version.

    Start Emacs.app, error messages are:

    I found libgcc_s.1.dylib at /Applications/Emacs.app/Contents/MacOS/lib/libgcc_s.1.dylib, seems the reference is wrong.

  • Error message when starting:

    Error message when starting: "1"

    I am absolutely willing to finally give native compilation a run. For this very reason, I fetched the latest "known working build" (2021-07-12 by the time of me writing this) and installed it on my Big Sur (Intel) MacBook. I renamed my init.el first so nothing could interfere with it yet. (I used other builds until today, but they don't have native compilation yet.)

    Anyway, I can't start Emacs.app.

    Thanks.

  • DBus support

    DBus support

    Is there any reason for not adding DBus support (--with-dbus flag)? It could be a useful addition with no real downsides. I don't know if there are any other feature flags that are left out but I think it would be wise to include them all (unless they have some really apparent downsides) in a pre-built version so that everyone can enjoy.

    Also thanks a lot, this project saved me quite a lot of time! DBus support would be a cherry on top.

  • Enable relative path for Emacs.app

    Enable relative path for Emacs.app

    I use Doom and seem to be running into an issue when running doom sync which I believe generates the autoload files that emacs needs to start. Seems that there are some hardcoded items from the build machine:

    doom doctorWarning: arch-dependent data dir '/Users/runner/work/emacs-builds/emacs-builds/sources/emacs-mirror-emacs-5784b42/nextstep/Emacs.app/Contents/MacOS/libexec/': No such file or directoryWarning: arch-independent data dir '/Users/runner/work/emacs-builds/emacs-builds/sources/emacs-mirror-emacs-5784b42/nextstep/Emacs.app/Contents/Resources/etc/': No such file or directoryWarning: Lisp directory '/Users/runner/work/emacs-builds/emacs-builds/sources/emacs-mirror-emacs-5784b42/nextstep/Emacs.app/Contents/Resources/lisp': No such file or directoryError: /Users/runner/work/emacs-builds/emacs-builds/sources/emacs-mirror-emacs-5784b42/nextstep/Emacs.app/Contents/Resources/etc/charsets: No such file or directoryEmacs will not function correctly without the character map files.Please check your installation!\

    Could these be turned into relative paths to enable items requiring these locations to run as expected please?

  • org-capture placeholders broken in current (28.0.50) known good build

    org-capture placeholders broken in current (28.0.50) known good build

    This resolved issue seems to be included in the as-of-today know good build: Emacs.2021-10-24.608e694.master.

    The issue prevents certain capture templates from working. For example those that prompt for a tag.

  • mu4e is missing in the builded app

    mu4e is missing in the builded app

    I installed your latest nightly from the emacs-28 and I got this error at startup

    Warning (initialization): An error occurred while loading ‘/Users/maikol/.emacs.d/init.el’:

Error in private config: config.el, (file-missing Cannot open load file No such file or directory mu4e)

    The temporary solution is to add this to the config

    (add-to-list 'load-path "/usr/local/share/emacs/site-lisp/mu/mu4e")

    I think that loading mu4e should be loading directly by the app instead of the user.

    Best.

    Thanks for this nice project! The emacs-28 branch was just created and the master branch has version 29.0.50. It would be nice to have separate build for Emacs 28 branch.

    Incorrect path to own Emacs.app in the built output!?

    I've just installed the builds you've published here, tried the latest (2021-05-17) and last known good according to #7 - 2021-05-10 but both fail for me in a similar way when run from a terminal:

    kll@mbp13:~$ emacs
Warning: arch-dependent data dir '/Users/runner/work/emacs-builds/emacs-builds/sources/emacs-mirror-emacs-28bed06/nextstep/Emacs.app/Contents/MacOS/libexec/': No such file or directory

Emacs will not function correctly without the character map files.
Please check your installation!

    IIRC /Users/runner is used by GitHub Actions, so is it possible that some path used during the build seeps over into the final build. I naturally do not have this directory. If I create it, like so:

    mkdir -p /Users/runner/work/emacs-builds/emacs-builds/sources/emacs-mirror-emacs-28bed06/nextstep/
sudo ln -s /Applications/Emacs.app /Users/runner/work/emacs-builds/emacs-builds/sources/emacs-mirror-emacs-28bed06/nextstep/

    then emacs works just fine!

    Is this something wrong on my machine? I only have a single Mac so difficult to test...

  • Automate stable and pretest builds

    Automate stable and pretest builds

    Right now I need to manually trigger the build GitHub Actions workflow with the relevant git tag ref to create a stable or pretest build.

    This should be automated by checking the list of git tags in the emacs-mirror/emacs repository nightly, and automatically triggering builds for any new stable or pretest builds.

    For each matching tag found, I think it would be reasonable to simply check if the expected GitHub release exists for it, and if not, trigger the workflow.

    A minimum version for stable and pretest builds should also set, as I don't believe there's any point in building anything before Emacs 27.1.

  • Known Good Nightly Builds

    Known Good Nightly Builds

    Nightly builds from the master branch of Emacs aren't always stable.

    Hence I maintain this list of nightly builds which I have personally used for at least 1-2 days with my personal config without noticing any issues.

    I offer no guarantee of how frequently this list will be updated, but I can say that I typically update to the latest nightly build somewhere between daily to once every 1-2 weeks.

    Homebrew Cask

    To install the latest known good nightly build via Homebrew, install the emacs-app-good cask from the jimeh/emacs-builds tap:

    brew tap jimeh/emacs-builds
brew install --cask emacs-app-good

    The emacs-app-good cask is automatically updated once a day against the below list.

  • Provide builds for various Linux distros

    Provide builds for various Linux distros

    This is a decent bit off, as it first requires a build script for Linux.

    The build-emacs-for-macos script used at the moment is macOS specific for obvious reasons. But I am planning a rewrite of it in Go, which allow me more flexibility, potentially opening the door for Linux support without too much effort. Time will tell.

  • Apple Silicon Native Builds

    Apple Silicon Native Builds

    Update (2021-11-30): Apple Silicon builds now purely depends on GitHub Actions having Apple Silicon based GitHub-hosted runners:

    https://github.com/actions/virtual-environments/issues/2187

    Main blocker for this right now is the lack of Apple Silicon support in GitHub Actions, as from what I understand it's not possible to build Emacs for Apple Silicon on an Intel machine. There is always the option of buying a Apple Silicon machine, but that'd go against my goal of keeping everything public and transparent, as I would be producing builds from custom self-hosted hardware, instead of GitHub hosted runners.

    ~~The secondary semi-blocker is that GCC and libgccjit are as of writing not yet available for Apple Silicon, meaning even if I had a Apple Silicon environment to produce builds from, native-comp would not be available.~~

  • Improve GitHub Releases (description, extra assets)

    Improve GitHub Releases (description, extra assets)

    Some of the things I'd like to add to each release:

    • [ ] Summary of what was built, potentially the plan.yml file contains everything needed.
    • [ ] Arguments passed to both ./configure and make. This will require changes in the build script.
    • [ ] Capture ./configure output and upload it as a release asset.
    • [ ] Add a code block to description with SHA256 sums for all attached assets. Potentially generated by simply combining the content of each *.sha256 asset.
    • [ ] Upload the Emacs source tarball downloaded by the build script as a asset on each release.

    For now these should all be relatively easy to deal with as each release will only have a single build for macOS 10.15 on x86_64. Once we get another OS or architecture the process will need to be able to deal with two concurrent builds attaching different assets and updating relevant parts of the description.
