I've seen posts about this every year, for at least the last 10 years. I'm not a MAC user myself. But from what I can recall it's a permissions issue. (my memory is rusty on this MAC stuff) You need to go into System and give the program "full access" to the hard drive. Exactly how you do that on a MAC, I haven't a clue. But until you do that, you won't be able to save to your hard drive.
