In any project as complex as an operating system, there are always bugs to be fixed, features to be sped up, and enhancements to add. That's why Windows has Automatic Updatesand why Apple has Software Update.
Whenever Apple comes up with a new software fix, this program can notify you, download the update, and install it into your System automatically.
Software Update doesn't automatically download the new software unless you turn on the "Download important updates in the background" checkbox. No matter what, though, Software Update always asks you before installing an update, as shown in Figure 13-13.
For maximum effortlessness, turn on the "Check for updates" checkbox and then select a frequency from the pop-up menudaily, weekly, or monthly.
