As with Windows, the Macintosh OS has a central location where you can alter all of the System Settings, called System Preferences in the the Macintosh OS. Unlike Windows, there is not much troubleshooting that you can accomplish with the Macintosh OS; this is were you would come if you would like to alter the look and feel, or the behavior of the Macintosh OS.

Again the title of each specific group of settings explains what each one does, but for clarity I will explain some of the more important groups of settings.

The Desktop Preferences is the place to come if you are interested in changing the background image. You can either choose from a default selection, or from any image/folder of images that you have on your computer. You can also set the OS to randomly change your background at a specified interval.

The Dock preferences controls the way that the Dock looks and behaves. The options you can set in here include: the size of the Dock, whether or not the icons magnify when you mouse over them, the dock's position, the minimizing effect, the icon animation (whether or not a program icon bounces when it starts), and a preference to hide the Dock when you are not using it.

This is where all of the preferences that did not seem to have a specific function are. The options in here include the button, and scroll bar color, the object highlighting color (what color the background is when you highlight text), scroll bar options, history length, and font smoothing options.

This is where you would go if you needed to change a setting specifically related to your password. This Preference set is available to everyone regardless of whether or not they are an Administrator. In here you can change your password, your icon (if you are using a list of users), and there is also a quick link in here to update your Address Book Card (for email, etc).
Note: Again you can choose any image you want for you login picture; you do not need to settle for one of their default images.

This is the place where you set your screen saver preferences. In here you can select, and configure your screen saver, set the idle time limit for it's activation, determine whether or not the computer will be locked (require a password) afterwards, and, finally, you can set "Hot Corners" that will activate the screen saver when you place the mouse there; this is a very cool way to quickly lock your computer.

This Preference Panel is similar to the Settings tab in Window's Display Control Panel. Here you can adjust your desktop resolution and color depth. Adjusting the desktop resolution can sometimes seem anti-intuitive since the bigger the number, the smaller things appear on your screen. This is simply because you can a larger area specified, therefore the images/text take up a smaller percentage of that space.

Here you adjust the times at which your computer goes to sleep. There are two sets of settings, and you can adjust them either together or individually. There is a setting for your display and another for your computer. Your display can never go to sleep after your computer. When in "sleep" mode your computer uses a very minimal amount of electricity.

This is where you can set all of your network preferences. You should never alter anything in this Preference Pane, except for one exception noted below, unless you either know enough about your network structure, or you have been given information from your Network Administrator on which values to change. You can, however, alter either the method in which you connect to the network (ethernet, airport, etc.) or you can change your location. You would only have two different locations if you connected to two different networks on a regular basis (at home/school/work, LAN/WAN, etc.).

This Preference Pane controls your network sharing settings. The Macintosh OS X sharing settings are very primitive (as of OS 10.2.6) in that you can only share one folder, and that is your Public folder in your Home directory (/Users/User name/Public/). Once you have turned on your File Sharing, anything that you put in this folder can be seen across the network under the computer whose name appears within the Sharing Preference Pane. There are many types of ways you can share these files, but most users would probably only want to start the Personal File Sharing and the WIndows File sharing settings.

Only Administrators have access the the Accounts Preferences. In here you can: add users, edit users - including all of the settings that were under My Account, delete users, set a specific account that automatically logs into the computer every time it starts up, and you can also change the way users log in to the computer (a list of users, or by name and password).

OS X is so different from OS 9 that you have to have a OS 9 System Folder installed in order to run old applications. If you do have a OS 9 System Folder installed you can either set it to load on startup, or when you launch an older application, which would depend on the amount on resources your computer has available to it. In this Preference Pane you can conduct all of the operations you used to in OS 9, such as Rebuilding the Desktop, and Starting with Extensions Off; these options only apply to your OS 9 environment though.

As the name suggests this is where you can change all the settings that have anything to do with your computer's date and/or time. In this Preference Pane you can change your computer's date, set your time zone, and change the way your date appears in the menu bar. Another feature, similar to the Windows Date and Time Control Panel, is the Network Time. Again, I highly recommend that this feature is turned on; with this feature you never again have to worry about setting your clock as is does so automatically.

This Preference Pane is similar to the Windows Update option. This group of settings allows you to set: how often your computer checks for updates, and allows you to review previously installed updates. You can also force your computer to check for updates by clicking on "Check Now". It is always imperative to keep your computer up-to-date, as often updates fix bugs and security vulnerabilities.

Your Startup Disk is the System Folder your computer will boot off of. If you have separate operating systems installed on your computer, you can alter which one will boot when your computer restarts. An example for why to use this would be if you are trying to run a program that should run in your Classic environment, but will not for some reason. One possible fix for this may be to change your Startup disk to the OS 9 system and restart so that you are truly running in OS 9.
