I use Daniel Jalkut’s MarsEdit everyday to publish articles, update pages and fix typos here on 512 Pixels. It’s the best WordPress client I’ve ever used, including the WordPress web dashboard.
Version 4 comes with an updated design that looks much more at home in our post-Yosemite world. WordPress users can now set the featured image for posts, set the Post Format and change the author of published posts. The app can now download the entire history of published posts and pages locally and preview Markdown, MultiMarkdown and “Convert Line Breaks” content before publishing.
The app can be used as a 14 day trial period and requires macOS Sierra. A full license will run you $49.95, with a $24.95 upgrade available to MarsEdit 3 owners, even those who purchased on the Mac App Store, thanks to a new in-app purchase in version 3.
