Hi again,
Glad it's working. Like I said in earlier posts, you have to set the Apple Display Preferences in System Preferences. The trick is to Gather Windows and see them all. Then you change the resolution of the VGA/HDMI projector built into the Einscan-S and everything should be OK.
You'll know it's working because when you click on Arrangement you'll see the small screen next to your others, and your desktop picture will be projected by default.
Parallels looks at the default OSX system, but there was a bug on the earlier versions with extended desktops, and you had to uncheck Use OSX Full Screen.
I haven't managed to download the update, it seems to fail at the last minute.

Mike
PS Scan looks well resolved.
