If you'd like to stay on top of the game, download our nightly builds. These are produced from current development snapshots of GNU Emacs and Aquamacs, straight from their respective repositories.
Building the nightlies may fail occasionally - that's part of why we do them. If that happens and you're tech savvy, please do check the log provided and try to fix the problem.
To work around this, just double-click on the app in Finder while holding the Control button. You only need to do this once.
You can verify the source of your download by making sure that it comes from "aquamacs.org", the official internet domain of the Aquamacs project.
These builds are updated regularly. This is most likely what you're looking for! Recent commits
