i bought my daughter a mid 2012 macbook air 13" its was fine for a couple months now all of a sudden it wont turn on. well actually it turns on and does this,
it takes about 10 minutes for the progress bar to finish then it shuts down and does nothing till i press the power botton to turn it back on and does it all over again with the progress bar and shuts down again,over and over. I've tried to restart it about 4/5 times and still the same thing!
thanks for any advice.
