I purchased this for use with my new Imac only to learn that many many MAC users have problems getting the Mac to recognize the device. Despite the fact that these complaints are widespread, Iomega and its software company don't disclose the problem or provide information on a fix or work around. I've never written an amazon review before but felt obligated to warn others. If you are looking for a back up drive to use with a MAC this is not for you. Iomega's customer support (which charges $25 per call) is the worst I've ever encountered. You know that seen in Office Space where they smash the printer? If you have a MAC you too will dream about using a baseball bat on the Iomega 500 gb.
