There can be various kinds of Mac OS X 10.6 Snow Leopard problems which can be caused by corruption of the directory of your Mac operating system startup disk, permissions on system files or folders and system, application or user-specific cache files. Some reasons of such corruption are mentioned below:
- bad sectors on your Mac startup disk
- system or application gets damaged
- restaring a system that freezes with the power button
- application installers that reset system-related permissions wrongly may also be one of the cause
