Introduction

In order to keep your Mac secure and operating efficiently it is important that you always install software updates as they become available. These updates not only fix problems with applications and the operating system, but also fix security vulnerabilities that can be used by computer viruses to infect your computer. Unfortunately, many people feel that because they are using a Mac they are much more secure and thus may not be as diligent in updating their software as they would on a Windows machine where viruses are much more common. The reality, though, is that any operating system, regardless of who makes it, constantly introduces security vulnerabilities that need to be fixed. Therefore, it is important to remember that though you may be using a Mac, even they are vulnerable to computer infections as shown by the recent Backdoor.Flashback Trojan.

With that said, updating your operating system and its installed applications so that they are using the latest versions and patches is imperative to having a healthy and usable computer. This tutorial will walk you through updating your Mac computer as well as configuring it to automatically alert you when new updates are available.

Once you have reviewed the available updates, click on the Install button to start the update process.

The operating system will now install all of the updates that were listed in the screen above. While the updates are being installed you will see a status screen similar to the one below.
