Hi, I was wondering if you can help me figure out with this issue: My macbook pro won't start to the log in display. It gets stuck to the gray apple logo with the progress indicator, and stays on that stage for several minutes. I tried turning it off and on, also tried starting it in safe mode, yet it still gets stuck on that stage. Any advice? This is the first time I encountered this with my macbook pro. Prior to this, I installed TrueCrypt and created a hidden volume. Could this have affected my start up?
