Review title: Doesn't work with Mac OS X Product review: I was very excited to get this product (Coby DP- 151, digital photo key chain), and wanted to download pictures of my kids for my mother for Christmas. The software downloaded fine, I was able to transfer pictures to the software, but when I went to download the pictures to the photo key chain the application quit. Tried several trouble shooting techniques with no luck, including going to Coby's website. Called Coby and was informed that there is a glitch with the software for Mac computers. So this product will not work for me. I do have to say that the website was easy to navigate and customer service at Colby was quick, friendly, American, and helpful. But don't buy this product if you have a Mac unless you verify the software will work first.
