From the developer:
Marxico is a delicate Markdown editor for Evernote. With reliable storage and sync powered by Evernote, Marxico offers a great writing experience. The program supports code highlight, LaTeX and flow charts, inserting images and attachments by all means. Also, it is deeply integrated with Evernote, supporting notebook and tags, two-way bind editing, and more.
You may want to check out more software for Mac, such as Blurb Tally, Pads X or iTeXMac, which might be similar to Marxico.
