White screen, apple logo, spinning wheel and no boot
Hey!! I am facing almost the same problem. I own a macbook air and when I turn it on, the start-up chime follows, then a white screen with the apple logo, a spinning wheel and a progress bar appear. Once the progress bar is a quarter loaded it disappears, the logo and spinning wheel remaining there for ages, not doing anything. I tried resetting PRAM, safe mode boot which won't work, forced it to turn off and on a number of times and still doesn't work. Should probably mentinon that this happened after i tried to update the software, which of course failed. up until that point it had trouble loading and the system kept freezing.I would be extremly grateful if you could help me..
