I'm beginning to think that TT support doesn't know the difference between a Windows machine and a Mac. I've had this slow dance with TT since sometime in Sept., when I asked if TT Home provided advance planning for Mac. The TT site said, and still says, that Macs can't do that. TT support has said it can, and sometime last month, TT provided me a screenshot showing me how to access advance planning -- by clicking on the icon of the TT910 screen. I may have done that several hundred times since I bought the TT in late Aug, with no effect except the line above the large TT screen, "At this time there is no component that is compatible with your computer" or some such thing.
Tonight I took a closer look at the screenshot from TT. It's clearly a Windows screenshot, not from a Mac at all.
I've asked for a screenshot from a Mac, but at this point I'm not sure if anyone there knows the difference.
