Hi! My MacBook (Intel, 15 months old), froze while I was using it and then I had to forcibly shut it down by holding down the Power button. After that it just didn't start up. A flickering Question mark was all I was met with. I could not run the Apple Hardware Test with the Snow Leopard installation The AHT results tell me that there is no problem with the MacBook's hardware and I should check the software. But the profile doesn't list the Macintosh HD at all. And neither does the Startup Disk. I welcome suggestions to overcome my problem, considering the fact that Techtool Pro reported that there was no problem with the Mac HD after an intensive scan which included a surface scan. And I didn't drop the notebook either. -- Regards Isaak Mogetutu Twitter: twitter.com/mogetutu Skype: mogetutu
