It's within the basic hardware preferences that you configure the behavior of the CDs and DVDs you insert in your Mac, how your Mac's display is configured, and the noises your Mac makes and receives. Let's start with DVDs and CDs by going to System Preferences here under Hardware. If you are tired of your Mac doing the wrong thing when you insert a CD or DVD, here's where you change that behavior. So for example you inserted a blank CD. By default it says ask what to do. You can also have it, Open Finder, Open iTunes, Open Disk Utility or Open another application. For example, blank DVD, same idea.
When you insert a music CD, by default it opens iTunes and that make sense given that iTunes is the Mac's default music player. When you insert a picture CD, it's going to open up in iPhoto. That makes sense, but if you're using a different photo viewing application, say Aperture for example, you may want to change that. If you have Aperture installed, it will appear in this menu. Otherwise you can choose to open it in another application. And when you insert a video DVD. Open DVD Player, again, you can choose a different application if you want to use that application with your DVDs.
Now take a look at Displays by going to the View menu. It's within displays that you choose your Mac's display resolution. The larger the number, the smaller the objects onscreen and the more that fit. In some cases you'll also be able to control brightness. It depends on what kind of setup you've got, whether you've got a laptop or whether you've got a monitor that accepts brightness controls. If you click the Color tab, you'll find that you can choose different display profiles and this will change the look of your monitor. Maybe it'll make it a little more yellow or little hotter or little bluer.
You can also calibrate your monitor, if you want. You do that by clicking Calibrate, and then you walk through this little wizard that will help you tweak the look of your monitor. We won't run through that right now. Here's a little tip for you. If you don't happen to be in the Display system preference, you can easily move to it by holding down the Option key and then pressing F1 or F2, and that automatically opens the Display System Preference. Now let's take a look at Sound. Here's our Sound system preference.
The Sound system preference not only controls your Mac system's sounds, but it also controls the inputs and outputs. So here are the sound effects you Mac make when it makes an error, and funk. You can also choose an output device if you happen to have it, so it can be Internal Speakers, Line Out, Digital Out. We have an advanced audio interface connected to this computer. You can choose whether you want to play user interface sounds or not, and you can also play feedback when the volume is changed and that means if you've hit the volume control, we hear this little blip, blip, blip, blip, blip, blip, blip, blip, blip, blip, as you go on.
And you can see that the volume slider changes as you do that and that's what that's for. That drops the volume or raises it or you can mute things altogether by clicking on the Mute button. If you like you can show the volume in the menu bar, and then change the volume from there. Also, hold down the Option key click on that Volume menu and you can get directly to your Sound preferences. I want to take that out of the menu bar. Output, again, you decide where you want the sound to come out.
You can have it come out your Line Out, Digital Out, Internal Speakers or other audio interfaces. You can also change the balance, so you have the audio come out completely from the right speaker, completely from the left, or somewhere in between. You have a separate output volume control just for the output port. Again, Show volume in menu bar if you like, and then there's the Input tab too and there's my voice. You can tell that I'm talking because here's the input level meter. Same idea, you can choose how the sound is going to come into your Mac, either with your Line In, Digital In as we're using, or some kind of interface that's connected.
And there is one more trick for getting to the Sound system preference. If you hold down Option+F10, F11 or F12, up pops the Sound system preference. And simple enough. You now understand how to configure your Mac's Display and Sound system preferences, as well as command what disks do when you insert them in your Mac.
