The core component of any operating system is the kernel. It is the same, even in the case of Mac OS. The majority of the management processes like, memory and file management in an operating system is done by the kernel, and hence it plays a very crucial role in the successful working of the operating system. However, the main role of the kernel, is that it is essential for the kernel to be error free, for the system to boot successfully.
Any damage to the kernel renders the operating system completely useless, as the operating system does not get loaded. Damage might come in the form of faulty startup disk or unexpected shutdown of the system. Backup is no doubt the best option, to avoid data loss in such critical scenarios, but failure to have an updated backup, invites trouble to some extent. The absence of an updated backup makes the need for a Mac data recovery software necessary.
Mac hard drive recovery can be done efficiently by making use of REMO Recover (Mac) Pro Edition software. This powerful Mac recovery software, can recover lost or missing partitions with ease. The software can also be used to recover data from non-booting drives. This can be done by connecting the affected drive to a healthy drive, and recovering data using the healthy drive.
