In most of the scenarios damage to operating systems result in loss of some of the important files and folders. It creates great panic and frustration for the user.  Other major issues which lead Mac OS to data loss situation are listed below

1. One of the major parts in data loss is played by some viruses, which attack directly at low level of the file system and duplicate all the content saved in the data files. In addition, it disturbs the whole working of the operating system.
2. If machine was not properly shutdown then some of the data files might be deleted and inaccessible.
3. Some of physical damages caused by fire, water and moisture exposure damage not only the system but also most of the data files, which can only be recovered by data recovery specialist.
