The Cutting Edge: Aquamacs Nightly Builds

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.

The list of changes to date is available.

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.

Reporting Problems

See here for details about how to file bug reports.

Unidentified Developer: Digital Signature

While regular Aquamacs releases are digitally signed, the nightly builds are not (for security reasons). This means that you may get an error message when first starting up a freshly downloaded Aquamacs: "Aquamacs can't be opened because it is from an unidentified developer.".

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.
