I bought a Mac Mini about 3 weeks ago, about 8 days prior to the release of the new models and wasn't all that upset as I am a very basic user, surfing, e-mail and some letter writing on Text Edit. However now I have discovered that there is a problem with my unit and at the very least the audio jack is malfunctioning and I suspect other problems ie: the font will not stay at the selected size, and I have to insert and re-insert discs at least a couple of times before they are being read. I checked with an Apple Tech and he told me that the problem(s) do seem to stem from a hardware issue and told me to return the unit to the Apple store I bought it from for repair or replacement. Obviously I would prefer to have the older unit replaced with the brand new model. Not used to working with Mac so wondering if there are any suggestions on how I approach this issue to achieve the best results?
