+## Apple Silicon
+
+Native builds for Apple Silicon is supported, but currently GitHub's M1-based
+Actions Runners are prohibitively expensive for nightly builds. Intel builds
+though do work on Apple Silicon machines via Rosetta2, with a minor performance
+impact.
+
+Due to the costs, Apple Silicon builds are for now only scheduled for the 1st of
+each month. The `emacs-app-monthly` Homebrew Cask will always be pointing at a
+release that includes Intel and Apple Silicon builds.
+
+Builds for stable releases of Emacs will also include both Intel and Apple
+Silicon builds.
+
+### Costs
+
+At time of writing (2023-11-21), an average Apple Silicon build uses around 17
+minutes of billable time, at a cost of $0.16 USD per minute, that comes out to
+around $2.72 per build. I am considering enabling sponsorship on this repository
+in an effort to cover the costs for more frequent Apple Silicon builds, and will
+update here if/when I have any news.

+## News / Recent Changes
+
+### 2023-11-22 — Apple Silicon builds, drop macOS 11 support
+
+Apple Silicon builds are now available, but limited to stable releases, and
+nightly builds on the 1st of each month due to the cost of using M1-based
+runners on GitHub Actions. Apple Silicon builds also require macOS 13 Ventura,
+as that is the oldest macOS version available on M1-based runners.
+
+Additionally, Intel builds minimum required macOS version has been increased
+from macOS 11 Big Sur, to macOS 12 Monterey. This was needed as Homebrew no
+longer supports Big Sur, leading to very lengthy and error prone builds as all
+Homebrew dependencies had to be installed from source.
+
+If dropping support for macOS 11 turns out to be a big issue, it may be possible
+to offer macOS 11 compatible builds on a less frequent schedule similar to what
+we're doing with Apple Silicon.
