I figure somebody is going to ask me why I have this question anyway, so I am going to start with a quick explanation. I have type 1 Diabetes. I recently started using the Omnipod which is an insulin delivery system that closely matches the way the pancreas works. Pods are easier alternatives to just using needles or a ‘pen,’ and this is one variation of the many pods available. It works with a thing called the PDM (personal diabetes manager I think) which is basically the brain of the operation that sends all the info to the pod that is attached to my body (insulin delivery information, etc). Anyway, it stores lots of information like BG records and insulin delivery information, and that info can be downloaded to your computer via USB. There are warnings that say “DO NOT PLUG INTO AN APPLE COMPUTER.” So I called tech support to ask why as I did not want to experiment with this $800 piece of equipment that my life literally depends on. The tech support guy said something about USB voltage on a mac and that if you plug it into one the device will pretty much kill itself to prevent it from being internally fried. He admitted to knowing little more than that it had to do with the USB voltage. Can anybody shed some light on this situation. I apologize for the long explanation.
