I haven't done it myself. But in case I had to work for Mac and could not get access to Mac hardware, that would be the way to go.
You can get free gcc compiler for MAC (just Google for it) and Qt Mac download contains QtCreator according Nokia WEB site, so you automatically get an IDE.

If you are working on a commercial project, you should also estimate the time needed to set up a Mac environment in a virtual machine and compare it to the cost of Mac hardware. Maybe you can convince your employer buying a Mac.
