Mac OS X is a Unix-based operating system, which supports a number of data structures that are used in Unix operating system and Kernel is one among them. Kernel is the core component of Mac OS X operating system that is stored at protected area of hard drive. Kernel offers a number of advanced system services, such as file management, process management, memory management, and Input/Output management. However, in some situations the Kernel may become unresponsive and your system does not boot up. This behavior leads to data loss and put you in need of Mac data recovery solutions.
It is essential for a Mac OS X system to have a valid and intact Kernel to work properly. When Kernel fails to load, your system shows weired symptoms. To illustrate this problem with Mac OS X 10.5 Snow Leopard operating system, you may encounter gray screen with Apple logo. The system freezes at boot up and boot process does not complete. You may also see a spinning wheel at the same time, which is also called beach ball of death.
