@odd For me it worked flawlessly! There’s a very helpful ‘export wizard’ in the Mac app, guiding you step by step. I also love the way almost all formatting stays intact (in only a few posts, iframe embeds showed up as code block in DayOne for instance). The only downside is that it cannot do partial exports (or incremental imports) as of yet. A true syncing solution would be awesome, but for now I’m more than happy with it. (Although I wouldn’t mind hearing how @manton wants to improve this even further :)
