For weblogging, I prefer to use MarsEdit, a weblog editor for Mac OS X by Red Sweater Software. But using MarsEdit, or most other apps for that matter, on different machines can be a pain if you don’t take the time to set things up properly.
Enter Dropbox.
The free version of Dropbox provides 2 GB of hard drive space that you can access from any computer. Just toss files into your Dropbox and they automatically sync up. Throwing files that you create into your Dropbox is one thing, throwing app-specific data files, such as those that MarsEdit relies on, is another. The former is a simple matter, while the latter takes a bit more work. The answer to ‘making it work’ can be found on the Red Sweater forum.
Basically, you need to move your ‘Local Drafts’ folder to Dropbox and then create a symbolic link that points to it. Each machine that is going to run MarsEdit should have a symbolic link pointing to the drafts folder on your Dropbox. In this way, you can create a draft on one machine and finish it on another.
Another piece of the puzzle that I had to solve was moving over my existing MarsEdit data to a new machine. By moving my existing data, I wouldn’t have to configure all of my blogs on the new machine. The answer to that issue can also be found on the Red Sweater forum. Ultimately, it involves moving the main MarsEdit data folder and the MarsEdit preference file.
Now I have multiple machine MarsEdit bliss. I hope this helps you blog from anywhere.
