Hello, I have been asked by a friend to reload their black 13" MacBook with a fresh install of OS X. I have a copy of Snow Leopard with which to do the job. The problem is that the system seems to stop doing much of anything around the point where there's ~17 minutes remaining, then after about 10 minutes, the system just powers off. Here are some quick bits of information: -- I did a complete format (erase) in Disk Utility before starting the install. -- The system is plugged into a power source. -- I have tried with two separate OS X install DVDs. -- The system worked fine before starting this process. No reports of issues that seemed hardware-related. Any idea what could be wrong? What else can I try?
