I've done the update - works fine. A couple of points for Mac installation: 1. Follow the instructions regarding the removal of certain files from the System Folder, but make sure you leave the file called "E990 Driver" in the Extensions folder. If this file isn't present during the upgrade, you will get the "camera not connected" error. 1. Before running the upgrade application, give it more memory (say 20MB). This should prevent Type 1 crashes some people have experienced during the upload.
