I was having a problem with my Imac and connecting via ethernet. I live near Apple Stores. They have an electronic circus type atmosphere. The people you speak with at the Genius Bar aren't necessarily the people who work on your equipment. All that is missing is their Mickey Mouse ears. Then I discovered MacMedia, a seriously run efficient business offering equipment and service, both carry in or on site. What a pleasure to do business with. They are approved by Apple and honor Apple Care. I can't say enough good things about dealing with this Company.
