There's a lot less demand for Mac OS specific applications on Linux than there is for Windows. A lot more people start with Windows and try to move to Linux (bringing their windows applications in wine with them) than start with Mac OS and try to switch. Not to mention the Wine project goes way way back, whereas Mac OS really only started to get popular (again) with Mac OS X.
