[quote author="Benjamin Poulain" date="1287228578"]I don't think you can develop for S60 on Mac. I think the tools are simply not available for Mac (compilers, simulators, etc).[/quote]
To develop for Symbian on Mac there is the remote compiler (it is available again for Mac in the latest Nokia Qt SDK release). It still experimental but works fine for simple projects (at least in the Linux version). AFAIK, the simulator is not available.
About Qt Mobility. How did you try to install it?
'Help->Start Updater then select Qt Mobility in the package manager' - Is it available on Mac version?
