FDM SW2 software works fine via Parallels on my Intel iMac. However Apple have thrown a spanner in the works by introducing Macs with the new Apple M1 processor with which standard Win 10 cannot be run. Have installed latest Parallels on my new M1 MacBook Air and also the pre release Win10 ARM 64 VHDX software but FDM SW2 software only installs so far and then hangs. Obviously not compatible. Would be nice if there was a an ARM64 version of the FDM SW2 software at some point in the future(or even a Mac version!!) but I won't hold my breath.
