If you have time, make sure to watch the video on this page where I explain the evolution of the hard drive/SSD on the MacBook, along with a quick fix for a flashing folder on a MacBook Pro.
The Mac OS is only supplied with Apple computers. Many users cite the operating system as one of the reasons they buy Apple hardware. It is extremely reliable and known for its stability, so it is unlikely the root of the problem but it is possible.
