Rod Sprague,
Thanks for your feedback. I've followed your suggestion and created a test contact on my iPhone then synced with iTunes (and, as it didn't copy) with Sync Mate as well, after which it still didn't copy. FYI the reason I purchased Sync Mate is that I kept losing my personal Ring Tone when syncing with iTunes. Since I've used mainly Sync Mate my personal ring tone has stayed in place. As I don't use iTunes for what interests Apple = buying and storing music and the App Store, a simple sync program is all I need.
By the way my iTunes is set to Backup to this computer.
As for this Mavericks "blockage" I found out that it was an "Apple thing" by reading up on the Internet where one site said that Apple were sitting tight unless many people complained about having to use iCloud. What surprises me is that some people say that they can sync with a cable under Mavericks ........... I am not a genius by any means but I did work as a computer tech (with Windows) at one stage, on the other hand, I don't consider myself a complete idiot either.
