Is there a good / acceptable blog-publishing application on Mac OS X?

On Windows, there is the pretty good Windows Live Writer. I have always been told that there is no equivalent on Mac.

What would be the best alternative?

Some details about pros/cons, missing features, cool tips would be appreciated. I will make this question community wiki.

One of the best applications is MarsEdit (40$) by Red Sweater Software. It supports many blog types (including Tumblr), and allows both HTML and Rich Text editing. I think it also allows editing Wordpress pages and not only blog posts. It handles image uploading, editing of posts and supports multiple blogs.

Some of the cons of MarsEdit are its HTML editing shortcuts and macros which are a little uncomfortable and a bit too little.

If you're comfortable with HTML, then the known TextMate text editor can also be used as an editor for blog posts and then you can either copy/paste from there or use a blogging bundle which will let you upload from there. TextMate can also show you live preview of your HTML in a separate window.

Of course, being a specialized application, MarsEdit is more feature rich in the blogging sense but TextMate has a better editor (obviously).

Blogo, which was discontinued earlier, is back again. If you are on a Mac looking for a blog editor app, you should try it. You can download the beta for free at:

There is also a cross platform solution called BlueGriffon that looks promising.

My current recommendation and favorite is Blogo.

Easily publish text, images, videos, slideshows and more. With a simple, intuitive interface and support for Wordpress, Blogger, Typepad, Typo, Drupal, Joomla, and Expression Engine, Blogo is the best way to maintain your blog and spread the word with Twitter, Ping.fm and other supported services.

It also supports Twitter.

The closest to WLW would be Ecto, but active development seems to have stopped.
