Answer 1

Wow, way to plagiarize, Linux OS(btw, why did you name yourself that? Doesn't make any sense...). And you didn't even answer the question. How sad.

There are a few ways to use Google Talk with Macintosh computers. Of course, you need a Google account, and a compatible client. I use Adium[1]. You can also use many other clients, or just use the one Google provides in your GMail account. And, as mentioned above(the one thing that guy with the stupidly chosen name did get right), you can see a list of compatible clients on Google[2].

iChat is an AOL Instant Messenger (AIM), ICQ, .Mac and Jabber client for Mac OS X. Using a Jabber-like protocol and Bonjour for user discovery, it also allows for LAN communication. iChat's AIM support is fully endorsed by AOL, and uses their official implementation of the AIM OSCAR protocol. Using a Jabber transport, iChat users may also integrate their MSN and Yahoo! contacts into the Jabber pane, so only one instant messenger program is needed on a Mac.

It bears a brushed metal interface (as of Mac OS 10.4) and uses speech bubbles and pictures that are meant to personify the online chatting experience. With iChat, green (available), yellow (idle), and red (away) dots can be seen next to the name of each connected user on the buddy list.

There isn't a gmail chat, but there is Google Talk. Here is a list of chat clients for Mac OS X than can connect:

And as you can see, iChat is one of them :)
