Please!!! Make a Mac desktop app!
The web app is just not as powerful and a quite glitchey... having a desktop app for Mac would be ideal.
I know that getting this done could be huge or small....I don't know but even a constantly syncing desktop app would be better than just the web app.
Yes, yes and yes! Echoing the sentiments in previous comments, Macs are a very common platform for photographers. VMWare or inability to use some key features (by using the web app) are two not very good options to this dilemma.

We have the same frustrations as most photographers are mac-users...
We are in the same boat. Mac environment but using VMWare to allow us to run Windows and Stratus Desktop on our Mac machines. VMWare is VERY SLOW and slows everything else down too...so all are frustrated wondering when a Mac version will be released? The answer I thought was to be the web app but most of our team needs to use features the web app doesn't have so forced to use the desktop version at slow speeds.
