I tested MD on Mac a few days ago (rare occasion). It was a notebook with core2duo 2.4Ghz, 4GB ram, geforce 320m.
Problems were:Mouse cursor did hide correctly. (unlike Minecraft on Mac, and Manic Digger on Ubuntu).
Menu:I think a complete menu system should be made inside opengl window for all platforms (including mobile phones). Start.exe will be removed. This is top priority, because it's currently impossible to start game on Linux and Mac (no server list). Thread about menu:

Server list (I don't like the actual way to present the server list. Would it be possible to have some kind of HTTP API that returns the list in XML or JSON ?)
http://fragmer.net/md/xml.php - there is also POST api for logging in and account verification! i'll post when i find irc log where Fragmer tells details. (I can't access c:\documents and settings\...\irclogs after windows reinstall.)
