Athens LightMarkdown editor for Mac
Open a markdown file.
Edit it. That's it.
Athens Light edits .md files as rich text and saves them back to the same file. It is 3 MB, free, and open source. No vaults, no sync, no toolbar.
Apple silicon Macs only for now. The app is not notarized yet, so macOS asks you to confirm it once. After you drag it to Applications, run this:
$
xattr -dr com.apple.quarantine "/Applications/Athens Light.app"

Good to know
Your first edit to a file rewrites the whole file in the editor's markdown style. Bullets, spacing and unsupported syntax such as front matter can change. Athens Light is for notes and docs, not for files where exact formatting matters.
