iChat is Mac OSX Lion’s built-in answer to instant messaging. Of course other instant messaging software runs on your Mac, but with iChat you can connect with your network of friends in multiple networks. iChat is capable of linking you to your friends on Google Talk, Facebook, AIM, Jabber, and Yahoo.
Here are some of the things that you can do with iChat:
A new feature for Lion is the ability to use iChat for Yahoo Messenger. When you launch iChat, you will be asked to identify the type of chat account you want to set-up. Open the Preferences panel of iChat to go the Accounts pane. Click the + button to select which service you are going to be using and it will prompt you to enter the login information for that specific account. You can do this several times until you have entered.
2. Talk the night away.
Can’t have your friends over because they live hundreds of miles away? Or do you have news you can’t wait to share with your family? iChat’s audio conferencing feature acts like a party-line or a phone line with multiple extensions. You can audio chat with as many as nine other people. Video conferencing allows as many as four people so you can actually grab a glass of wine and toast each other as if you were all in one living room.
There’s no need to spend money by meeting up on coffee shops or booking meeting rooms. With iChat you can work together on a project from the comforts of your own home. iChat allows direct machine-to-machine transfer of large files. Just drop it on the other person’s folder and he will be able to access it. iChat Theater even allows you to open a file so you can see documents and presentations. No need for a file transfer. Even better, you don’t have to get frustrated trying to explain how to do a certain thing. Through iChat, you can see and control the screen of the other person or even show your screen so he can understand what you meant. To use this feature all people in the conference need to use iChat.
