Software publishers offer frequent updates for their software to enhance the product features and fix bugs. You can find several such updates for Mac OS X operating system.

However some updates may prove faulty and can cause serious problems with your system. It may lead to data loss and require Mac data recovery to be fixed.
For a practical instance of problematic updates for Mac OS X operating system, some of Mac OS X features may stop working after installing Mac OS X 10.5.6 update for Leopard operating system. This update is provided to improve the system performance, security, and graphical interface of iTunes, iChat, Cover Flow, and APERTURE applications.
The bad effect of this problem is with Time Machine, which is a backup tool for Mac OS X 10.5 Leopard and 10.6 Snow Leopard operating systems. It changes the working mechanism of the backup utility. After this update, Time Machine cannot restore the data from backup. If you face any data loss in the meantime due to accidental deletion, hard drive formatting, and operating system crash, you cannot recover Mac data using backup.
In fact the backup process of Time Machine utility is based upon the MAC address (an exclusive identification number that is assigned to the network interface cards or network adapters). The MAC address and your computer's name are stored in a file that is located at root of the Time Machine disk. Mac OS X 10.5.6 update changes the way in which Time Machine reads permissions.
