Our Mac did not start any more. We were completely helpless because it still functioned the day before. I brought it then in the service centre of the computer rescue car. The engineers there found fast the cause and repaired the device and I could fetch it after a few days again. Now everything runs again. Great!!!!
My broken device took there a good thing of the computers of rescue cars, and got back it after a short time repaired again. Thus this must be, very nicely.
