The new iOS 7 operating system for Macs laptops is causing a few backward compatibility issues . I have just been onto the phone with Dragon and they don’t have a patch to work with DD ver2.5 . This was bought about 12 months ago and sadly is now obsolete if you upgrade your apple system to Mavericks. You have to purchase DD ver 3.00 at a cost of £85. Why they don’t give a free upgrade to essential users I don’t know but this is the case. My advice is if you are a DD 2.5 user is to stay with your current operating system!
