Aquamacs
Aquamacs is a Mac-native build of GNU Emacs that helps you edit code, text, LaTeX, and other documents with familiar macOS behavior.
What is Aquamacs?
Aquamacs is a native macOS text editor built on GNU Emacs. It helps programmers, writers, researchers, and technical users work with source code, plain text, LaTeX, HTML, and many other file types in an editor that combines Emacs power with standard Mac interface conventions. Aquamacs supports familiar macOS menu layouts and keyboard shortcuts alongside traditional Emacs commands, which makes it easier to use on a Mac than a stock Emacs build. It can organize open files in tabs or separate windows, integrates with the macOS clipboard and spell checker, and supports Unicode text input and multilingual editing. Aquamacs also includes bundled tools and modes for workflows such as LaTeX editing, XML editing, statistics work with R, and version-controlled development. The project is maintained for Mac users who want a highly customizable editor with strong keyboard-driven workflows.

Safety overview
Status: Mostly safe
Aquamacs is a long-standing Mac editor distributed from its official site. Recent releases are described as signed and notarized, which is consistent with normal macOS app distribution. Because Aquamacs is an extensible editor that can run packages and custom Lisp code, install add-ons only from sources you trust and review any automation or shell commands before running them.
Recommendation: Keep Aquamacs if you use Emacs-style editing, LaTeX authoring, programming tools, or other text-heavy workflows on your Mac. If you no longer use it, removing the app mainly affects your editing environment and any custom settings or packages you rely on.
