I have actually been looking into this the past couple days: * The opensource toolchain of icestorm [1] is the only thing running natively on mac. * Most people run the vendor SDK on virtualbox under windows. * I heard also of people using wine/playonmac in rare cases. * I have tried installing the Icecube2 SDK from Lattice virtualized under Linux, because I didn't want to sacrifice the ~30GB discspace for a virtualized Windows. The installation was painful to say the least and I could not get it working on a recent Ubuntu versions because their license manager (Yes, the software is still free) has trouble with the network interface names (expects an eth0 interface).
