It absolutely will NOT work on a mac with the ebay postage software. There is zero compatability. Dymo software will work with normal programs formatted to the label. It will not work with the pitney bowes software/ java based app. I have heard there is an $80 third party app that will work and that if you use bulk shipping, it creates PDF's that will print. I will try to find the third party.
