Query: Don't buy this if you use a Mac

Yes, that's right. Don't buy this if you use a Mac. I am not computer illiterate, but suffered several hours of frustration with this unit. Even the manual (what there is of one) gives the wrong web address for Kodak's help section for digital frames. And the updates are img file format rather than dmg. Thanks for nothing, except the hole in my budget. That's all I have to say about it.
