I took them my Mac. It wouldn't boot at all. My dog chewed the power cord and fried the power supply. They got me a new power supply and installed it. I had it home the next day. I checked out prices before I brought it in and they are the cheapest around. I am very happy with this service and I will be going back anytime I need anything computer related. I highly recommend Wooten Computer to anyone who wants their computer work done right, fast and inexpensively.
