According to their website, you can share an application installed on the VM with Mac OS. Hypothetically, I should be able to right click the file in Mac OS > Open with > and the VM (in this case, Vista) app should display as an option. I don't see it and I haven't been able to tweak the setting to get this to work the way it should. Any help is greatly appreciated. FYI I have enabled "SmartSelect" and have check the appropriate boxes to share Windows and Mac OS applications
