When I turn on my Macbook, the process bar can only go to roughly 70%. I sent my computer to apple technicians. They said all hardwares are working well and suggested me to reinstall the system. I did that, but during the reinstallation, the computer shut down automatically. After I turned it on again, it would continue to install a new system. I am not sure whether this is normal. But finishing the reinstallation doe not help solve the problem. Any idea about what to do? Thank you in advance!
