So I have an iMac (still under warranty),bought in online from Apple store. The DVD drive has failed and does not burn discs,also the WiFi card seems to be faulty since it constantly drops connection. I've booked an appointment at my local Apple store Genius bar,but I was wondering are these hardware issues what they deal with at genius bars,or are they just for more basic,software issues or broken iPad/iPhone screens? it's a bit difficult taking the iMac there,soI wanted to make sure Genius bar is the place to take the iMac for service? Or should I arrange service via a different method?
