Set Up iChat

To use iChat, you need to have either a .Mac or AIM screen name. This is because iChat stores your Buddy List (your contacts) on its servers, and you need to identify yourself individually; no two people can have the same user name .

If you’ve already got a .Mac account, and either entered this information when installing Mac OS X, or done so in the .Mac preference pane (see Chapter 11), you won’t need to do anything special to use iChat. If not, you’ll need to enter your account information when starting up iChat.

When you open iChat AV for the first time, an assistant displays to help you set up your account. The first screen is a welcome screen. Read this, and then click Continue.

If you have either a .Mac or AIM account, enter your information in the next screen.

If you don’t have an account, click Get An iChat Account. This takes you to a web page where you can sign up for a free 60-day trial .Mac account. (This is not a permanent .Mac account, but if you don’t pay for it after the 60-day period, you’ll keep your screen name.)

If you have an AIM screen name, select the Account Type pop-up menu, and then select AIM Account. You can get a free AIM account by going to http://my.screenname.aol.com.

After you’ve entered your account information, click Continue. The next screen asks you if you want to turn on Rendezvous messaging.

Rendezvous messaging lets you communicate with other users on a local network. If you use a local network, you should turn this on. If not, check Do Not Use Rendezvous Messaging. Click Continue.

The next screen lets you set up your video camera, if your Mac supports videoconferencing and if you have an appropriate camera. All it does is show if your camera is indeed functioning, and shows the image your camera displays. Move your camera until the image is correct, and then click Continue.

The final screen tells you that you have successfully set up iChat and are ready to use it. Click Done. When you do this, iChat will display one or two windows : it displays a Buddy List window, and, if you’ve activated Rendezvous messaging, it displays a Rendezvous window as well.

The Rendezvous window shows all available users on your local network. The Buddy List window shows all the users you have added to your Buddy List. If you have just started using iChat, your Buddy List will be empty; if you have used it in the past, you may have several users already in your Buddy List.

My family and friends are very geographically dispersed, covering most of the United States, Canada, and parts of Europe. Keeping in touch regularly is a constant struggle. There are letters , of course, but who has time to write those? And phone calls, but those can cost a lot of money, especially for overseas calls.

Thanks to the release of Apple's iChat AV and iSight camera, communication among
my family has improved greatly. Although not all of them are enlightened enough to use a Mac, they all have AIM user IDs, which means we can at least have text chats regularly. But the real joy comes in talking to those friends and relatives who do use a Mac. With iChat AV and a video camera on both machines, it's possible to have very high quality audio and/or video conversations with a couple of mouse clicks. I have been able to have face-to-face conversations with people scattered from Denver to Washington, D.C. and from the Netherlands to a small village in France, all without paying for long distance charges. The quality of the audio and video, even on the international connections, continues to amaze me. Depending on the distance and the speed of both people's connections, it can almost be like having the person in the same room with you.

One feature we use fairly regularly is iChat's ability to have a one-way video conversation with another Mac user. This is useful for giving house tours or showing “baby at play” video to those who don't happen to have a camera but do have iChat AV. We've also used this feature with our video camera to stream recorded video to friends and family.

As is typically the case with Apple's consumer products, iChat AV manages to take something incredibly complex (setting up audio and videoconferences) and reduce it to an amazing level of simplicity, providing true power behind the simple interface.

Add Users to Your Buddy List

To add a user to your Buddy List, click the + button at the bottom of the Buddy List window. This displays a sheet showing all the contacts in your Address Book. (See Chapter 15 for more on using Address Book.) Select one of these contacts, and then click Select Buddy. If their e-mail address is a mac.com address, they’ll be added to your Buddy List. If not, enter their .Mac account name or AIM screen name.

If you want to add a new person to your Buddy List, someone who is not in your Address Book, click New Person. Select the type of account they have (.Mac or AIM) from the Account Type pop-up menu, and then enter their Account Name.

You can also add their first name, last name, and e-mail address, which is recorded in your Address Book. Click Add to add them to your Buddy List. You’ll see the user’s name in your Buddy List window, followed by one or two icons:

If the user has audio or video capabilities, you’ll see a telephone icon (for audio) or a video camera icon (for video); otherwise , you can only carry out text chats with them. You’ll also see an icon for the user’s picture, if they have set one.

Before the user’s name, you’ll see one of three icons showing their availability: green means they are available, yellow means they are idle, and red means they are not available. If the user is offline, their name appears dimmed, and there is no colored icon in front of it.

While you may want your buddies to always know when you are online, you may also want to be left alone at times, especially when you're busy. You can change your iChat status to show others whether you're available to chat.

There are two ways to do this: the first is by using the Buddy List window. Beneath your user name is a small pop-up menu that displays your status. Click this menu to choose from Available, Away, Offline, or Custom status for both Available and Away. If you select one of the Custom menu items, you can type your own custom status in the text field. Select Edit Status Menu to add or delete any custom status messages you create.

You can also change your status by using the iChat status icon in your menu bar. To display this icon, select iChat Preferences, click General, and check Show Status In Menu Bar.

Click this icon to change your status, to initiate a chat with any of your available buddies, or to display your Buddy List if it is not visible.

Chat with Your Buddies

When you want to start chatting with one of your buddies, check to see if they are online and available. There are then two ways to start a chat: if you have the iChat icon displayed in your menu bar, just select the name of one of your buddies. In this case, a window displays (see Figure 10-11) asking how you want to chat.

Figure 10-11: Click the left button to start a text chat, the middle button to start an audio chat, and the right button to start a video chat. If your buddy doesn’t have audio or video capabilities, these buttons will be dimmed.

You can also select your buddy’s name in your Buddy List window and click one of the icons at the bottom of the window; these three icons are the same as those shown in Figure 10-11.

When someone wants to start a chat with you, a window will display showing their message, along with three buttons at the bottom of the window: Block, Decline, and Accept. To accept the chat, click Accept. You can block the user by clicking Block, or turn down their chat by clicking Decline.

If you start a text chat, you can type your first message in the chat window. Your buddy will get a message on their computer and can start chatting with you.

If you want to start an audio chat, select your buddy and click the audio chat button. When the chat begins, you’ll see a window like this:

This window displays your microphone volume at the top and allows you to set your speaker volume by moving the slider at the bottom.

Just speak into your microphone (either built into the screen of your Mac if you have an iMac, eMac, PowerBook, or iBook, or an external mike plugged into your Mac), and you can have a conversation with your buddy.

If you want to start a video chat, you need to have an appropriate FireWire video camera, such as Apple’s iSight. You just plug this into one of your Mac’s FireWire ports, set it up so it’s trained on you (by mounting it on your screen or desk), and start a new chat as described earlier in this section. Click the Video Chat button, and if the other user has a video camera, you’ll be able to talk to each other and see each other.
