If you are having trouble running Maxim DL with a Mac OS and Parallels, maybe the solution is to have windows running before you connect the Aluma camera. It seems to work for me. And it explains why the Maxim DL sometimes recognized my camera and sometimes did not. If this workaround proves to be successful, I owe this to a contribution by Surveyor 1 on Cloudy nights two years ago concerning his experience running a SBIG camera with VMware Fusion and Windows 7.
