Mac OS X makes communicating with other computers over the Internet easier than ever with iChat. You can talk to others over the Internet (like you do on a telephone), use full screen video to see and be seen by others while you converse, share programs and files, and collaborate on documents.
You can use iChat to exchange instant messages with a designated list of buddies over the Internet. An instant message is an online typewritten conversation in real-time between two or more buddies. Unlike an e-mail message, instant messages require both parties to be online, and the communication is instantaneous.
iChat makes setup effortless. The first time you launch iChat, a setup screen appears to walk you step-by-step through the process. During the setup process, you need to create or provide a screen name, which is your instant messaging address. If you already have an AOL Instant Messenger (AIM), Google Talk or Jabber account, you can use it with iChat. Otherwise, you can setup a .Mac account to get a screen name. To use the AV features of iChat, you need to have a microphone (for audio only) or FireWire compatible video camera (for audio and video) installed on your computer and a fast Internet connection. iChat allows you to communicate with either AIM or .Mac users (New!). Now you can talk to millions more people online.
In addition to using iChat over the Internet, you can also use it on your local network—known as bonjour messaging—at the office, school, or home. iChat automatically locates other local users who are logged in, and lets you send messages or files to each other.
The first time you launch iChat, a setup screen opens to walk you step-by-step through the process. To complete the process, you need to provide or create a screen name (your instant messaging address) to send and receive instant messages with iChat. If you already have a .Mac account, an AOL Instant Messenger (AIM) screen name, Google Talk account, or Jabber ID, you can use it with iChat (New!). A .Mac screen name is your e-mail address, such as [email protected], or an AIM screen name is a handle, such as perspection. If you don’t have a screen name, you can sign up for a .Mac account at Apple’s .Mac Web site during the setup process to get one. If you have multiple accounts, you can switch between them or use them separately (New!). You can’t use screen names from other instant messaging systems, such as MSN or Yahoo, with iChat. If you are using iChat over a local network for Bonjour messaging, you don’t need a screen name.
If necessary, install a microphone or compatible video camera according to product instructions.
Start iChat for the first time; display the Dock on the desktop, and then click the iChat icon.
Read the Welcome screen, and then click Continue.
Type your first and last name, if needed.
Click the Account Type pop-up, and then select an account: .Mac, AIM, Jabber, and Google Talk.
Type your Account Name and Password, and then click Continue.
Select options to setup audio and video for iChat, and then click Continue.
Click Done.
Click Accounts.
To create another account, click the Add (+) button, select an account type (.Mac, AIM, Jabber, and Google Talk), enter account name and password, and then click Done.
Your password is added to your keychain.
Click the Account Information tab.
Select one of the following options:
Use this account. Select to enable and display this account.
When iChat opens, automatically log in. Select to open this account when you start iChat.
Allow Multiple logins for this account (New!). Select to use multiple logins for this account.
Click the Close button.
iChat is an instant messaging program that allows you to exchange instant messages with a designated list of buddies over the Internet. An instant message is an online typewritten conversation in real time between two or more buddies. Instant messages require both parties to be online, and the communication is instantaneous. After you start iChat, you sign in to let others online know you are connected. When you’re done, you sign out.
Display the Dock on the desktop, and then click the iChat icon.
A Buddy List window opens, displaying a “Connecting” message. Upon completion, the Buddy List expands to list your buddies and their online status.
If you’re not automatically signed in, click the iChat menu, and then click Log In To <account>.
To sign out, click the iChat menu, and then click Log Out Of <account>.
When you sign in with iChat, the program notifies buddies currently online from your Buddy list that you are available to chat (green status). While you’re signed in, you might need to leave your computer for a meeting or lunch. Instead of signing out, you can change your online status (red) to let your buddies know that you’re busy, away from your desk, on the phone, or out to lunch. When your away, your buddies see that you’re idle, and any message you receive is waiting for you. If you don’t want your buddies to see or send messages to you, you can go offline. If you don’t want to be seen offline, you can go invisible (New!). If you don’t see the status message you want, you can quickly customize your status messages to suit your own needs.
If you turn on the iChat Status menu, you can still receive instant messages, view online buddies, and change your status when you quit the iChat program. The iChat Status menu appears as a chat balloon icon on the right side of the menu bar for all applications. When the ballon icon is empty, you’re online; when there is a line in the middle, you’re away or offline. If you don’t see the Status menu, you need to turn it on in the General pane of iChat Preferences. When the Status menu is turned off and you quit iChat, you’re logged out of AIM and Bonjour messaging.
Before you can send instant messages to other people, they need to be in your Buddy list. Your Buddy list shows you who’s currently online and offline, their audio and video capabilities, and if they are available for chatting. You can add a person who has a screen name from a .Mac account or AIM to your Buddy list. You can add as many buddies as you like to your Buddies list. You can add them from your Address Book or type new ones. When you add a new person to your Buddy list, a new card is added to your Address Book. Your Buddy list is stored on an instant message server, so you can log in to your account from any computer and see if your buddies are online.
If necessary, click the Window menu, and then click Buddy List to display the Buddy List window.
Click the Add (+) button in the Buddy List window, and then click Add Buddy.
Select an account, select a group, type the screen name for the person, or click the Expand/Collapse button, and then select an address from the Address Book.
Click Add.
You can change the picture that appears next to your name in the Buddy List and in message windows, along with the ones that appear next to your buddies. The picture is known as the Buddy icon. The Buddy icon you select appears in the Buddy List of those in which you have a chat. To change your Buddy icon, drag an image file—64 × 64 pixels is recommended—to your name in the Buddy List. In addition to an image file, you can also use an animated picture, also known as a GIF or animated GIF, as a buddy picture (New!), which you can also create using Photo Booth.
If necessary, click the Window menu, and then click Buddy List to display the Buddy List window.
Select the buddy you want to change.
Click the Buddies menu, and then click Show Info.
Click the Address Card tab.

Select the Always use this Picture check box.
Click the Close button.
As your Buddy list grows, you may want to organize your buddies into groups. iChat makes it easy to create your own groups and use the one predefined group called Buddies that comes with iChat. Once you have organized your groups, you can simply drag buddies from one group to another. You can use the check boxes next to the group name to hide and display buddies in a group. If a group changes, you can rename it, or if you no longer need a group, you can remove it.
If necessary, click the Window menu, and then click Buddy List to display the Buddy List window.
Select from the following options:
Display all group members. Click the View menu, and then click Use Groups or Use Offline Groups.

You can’t delete a group with buddies in multiple groups, but you can delete a group with the only one buddy in it. You can’t delete the last group in the list; you need to always have at least one.
Rename a group. Click the Add (+) button, click Edit Group, select the group, click the group again, type a new name, and then click OK..
An instant message is an online typewritten conversation in real-time between two or more buddies. As you type an instant message, you can format your messages by using fonts and color and by inserting graphical symbols called emoticons, or “smiley,” such as a happy face, which help convey your emotions. You can have instant message conversations with several different buddies at once. When you send a instant message to a group, all participants receive the message and all responses are visible to everyone involved. If you have multiple chat windows open at the same time, you can bring them all together into a single tabbed window (New!) to make it easier to manage. In order to use the tabbed window, you need to select the Collect chats into a single window option in the Messages pane in iChat Preferences.
If necessary, click the Window menu, and then click Buddy List.
To start a chat, select one or more names in the Buddy list you want to chat with, and then click the Start A Text Chat button.

To include pictures in your message, drag the image files to the area where you type.
To add another person to the chat, click the View menu, click Show Chat Participants, click the Add (+) button, and then click a person from your Buddy list or Other.
When you’re done, click the Close button to end the session.
If you no longer want to receive instant messages from a specific buddy, you can block the buddy from sending you instant messages. When you block a buddy, you appear to be offline to the person, who doesn’t know blocking is turned on. Blocking a buddy moves them from your Allow list to your Block list in the Privacy pane of iChat Preferences.
Click the iChat menu, and then click Preferences.

Select or clear the Block others from seeing that I am idle check box.
Click the Close button.
While you are conversing in iChat, you can send a buddy a file or hyperlink. You can send many different types of files, including pictures, documents, and music. When you send a picture, it’s displayed right beside your text in the Chat window. When you send any other type of file, a request to transfer the file is sent to your buddy. You are notified when your buddy accepts or declines your request. Before you receive files over the Internet, make sure you have virus protection software to protect your computer. You can also send a hyperlink that points to a Web site. When your buddy receives a message with a link, the person can click it to open the Web address in their Web browser.
Start a chat with the buddy to whom you want to send the file or hyperlink.
Type your message in the box at the bottom of the window.
Click the Edit menu, and then click one of the following:

Send a Hyperlink. Click Add Hyperlink, type a Web address, and then click OK.
Type any additional text if you want, and then press Return.
If you’re sending a picture, the image appears in the chat window; if it’s a file, wait for the recipient to accept or decline the file; or if it’s a hyperlink, the link appears in the chat window.
To open a file or hyperlink, click the file or link in the chat window.
When used with Leopard, iChat provides state-of-the-art computer communications features. With iChat, you can talk to others over the Internet as you do on a regular phone, and you can use video to see others and let others see you as you converse. Once you set up your computer hardware and software, you’re ready to communicate over the Internet. You have two communication choices: audio only, or audio and video. With audio only, you speak into a microphone and hear the other person’s response over your speakers. With audio and video, you send video to others so they receive live images as well as sound. If the buddies you call don’t have a video camera, they’ll see you, but you won’t see them. iChat supports only one video or audio chat at a time.
If necessary, click the Window menu, and then click Buddy List.
To start a chat, select a name in the Buddy list, and then click the Start A Video Chat button or Start An Audio Chat button.

The video effects are provided by Photo Booth and the backdrops are professionally designed by Apple. You can use the ones provided, download new ones, or create your own. If you have Leopard and a fast broadband Internet connection (384 Kbps or faster), you can host an iChat theater presentation (New!) that contains photos, keynote presentation slides, or movies from your desktop while your buddies view it on their computer in an iChat video window.

If you don’t have an instant message account or server, you can still use iChat to chat with others on your local network. Instead of communicating with a central Internet server, each computer communicates directly with each other over network cables. iChat also works with a wireless connection using AirPort over a local network or the Internet. Bonjour allows you to chat with people on your local network or wireless local community. You can’t add a Bonjour user to your Buddy list. The user names are based on the log-in settings on each person’s computer and are not AIM screen names. Unlike regular instant message, when you type a Bonjour instant message, each character you type is sent immediately unless you turn off the default setting in the Messages pane of iChat Preferences.
Click the Window menu, and then click Bonjour List.
The Bonjour window opens, showing iChat local network users who are available for chatting.
Double-click the user to whom you want to send an instant message.
Type your message in the box at the bottom of the window.
Press Return, and then wait for a reply.
When you’re done, click the Close button to end the session.
iChat makes it easy to customize the appearance of a chat to suit your own style and preference. You can modify the appearance of the balloons, or change a font style in a chat.
