LyX for MAC

Free, open-source document processor for Mac built on LaTeX: write by structure, not appearance, with a great math editor. Needs a TeX system.

LyX Overview

LyX is a document processor that encourages you to write based on the structure of your documents rather than their appearance. You say what each part is, such as a section or a caption, and LyX, working on top of LaTeX, takes care of the layout. It is well suited to scientific writing: its formula editor lets you enter equations with the mouse or with LaTeX commands and shows them rendered on screen right away, and you can insert plain LaTeX anywhere.

LyX is made by the LyX team and is free and open source under the GPL, version 2 or later. Version 2.5.3 is a maintenance release with bug fixes and speed improvements. The download is a universal app for Apple Silicon and Intel and needs macOS 12 or later; a separate build is offered for older Mac versions. Two things to know before you start: you must install a TeX system such as MacTeX first, and LyX is not notarized by Apple, so macOS warns you the first time you open it. On macOS Sequoia and later you allow it with Open Anyway in System Settings, under Privacy & Security.

What does LyX need to work?
