Blogging on a Mac with Kung-Log
There seems to be some issues with editing Movable Type posts on a Macintosh, it doesn't show you the formatting tools (bold, italics, underline, links). Well even if it did, you'd still want this software tool, it's called Kung-Log (for OS X) and it lets you do all that and more. Create thumbnails, different blogs, categoris, post drafts, customize your own HTML commands, save drafts on the hard drive (if not on-line) and edit (yes, I said edit) previous posts and it has a spell check.
This version requires MacOS 10.2 or higher and either a MovableType installation of version 2.6 or higher, Nucleus 1.55 or higher, or any weblog system supporting the MovableType, MetaWeblog and/or Blogger API.
