iChat (alias: iChat AV) is the OS X instant message applications software which Apple developed for operating system. I cope with an instant text message and a sound, a picture, a screen joint ownership function that I turn on XMPP/Jinglie () and OSCAR () (AIM) protocol. In addition, the local network discussion on having searched a user through Bonjour protocol is possible.
I finish development, and, as of February 16, 2012, iChat is replaced with a message of OS X 10.8 "Mountain Lion". I can download the general release beta release of the message on the website of the apple as of same February 16 when Apple announced the preview of OS X Mountain Lion.

In addition, an icon of green (I can talk and am in a state) yellow (idol state) red (I cannot talk and am in a state) is displayed next to each connection user name in the list of Buddy. I can change it to display status in the difference in shape as well as a color for the user of the color blindness.

What was released integrates a mail application with an address book in August, 2002 when Mac OS X v10.2 was announced, and it is to the thing which supported the AIM client corresponding to the native formally in Mac OS X (the AIM application of the first party still works by classic emulation once) first.

Apple announced "the iChat AV" which was the second major version of iChat in June, 2003. Video, audio conferencing function from Session Initiation Protocol (SIP) of the industry-wide standard was added. The most recent version was released with Mac OS X v10.3 and sold distinction for 29.95 dollars with released Mac OS X v10.2 [1].
iChat AV 2
In February, 2004, AOL announced AOL Instant Messenger (AIM) version 5.5 for Windows user, but the sound chat of the possible thing was impossible, and the video chat in AIM プロコトル was compatible with the iChat AV of the apple. The apple released beta release of iChat AV 2.1 that MAC OS X user could do AIM 5.5 user and a video meeting on the same day.
iChat AV 3
In June of the year, Steve Jobs announced the next version of the iChat AV contained by Mac OS X v10.4. I became able to participate to ten people to four people by iChat AV 3 in audio conferencing in one video meeting. In addition, I enabled the picture which was higher-resolution than the old version that used the H.263 codec by having adopted H.264/AVC codec in the new version of iChat. In addition, the user became able to be connected to the direct Google talking in a thing corresponding to XMPP プロコトル and came to be able to connect it to the user of the service including Facebook Chat and Yahoo! Messenger indirectly [2]. However, there was the limit to the support, too, and some functions of XMPP such as making and service Discovery () and the full multi user chat of the account did not support it. Bonjour プロコトル (former name Rendezvous) is included in iChat 3 again and becomes able to search a user enabling iChat Bonjour message on a user local network automatically [3].
In October, 2005, iChat supported the exchanges that I encrypted, but was applied to only a paid member of MobileMe (known as .Mac) of the apple. iChat 3.1 that contained these functions at the time of update to Mac OS X v10.4.3 was released. The correspondence to XMPP multi user chat was added in this version again.
In March, 2007, the apple updated Mac OS X in v10.4.9 and, as well as a camera for FireWire, became able to use USB video device class (UVC)-adaptive camera in iChat. Very various kinds of cameras became in this way available in iChat AV.

In the iChat theater, a user can share the Quick Look support file such as the picture of a photograph and basic tone presentation and the video chat session [4]. "Back drop" is the function that I can insert a photograph and a picture in in the background of the video chat, and, in Screen Sharing, two Mac OS X Leopard users operate the same desktop and are the function that can work jointly. There are the use of the Photo Booth effect, tab chat capability by multi-login, an animation icon, a live video chat elsewhere.

A sentence, a voice, the chat using the picture allowed the iChat user in Yahoo Mail account in iChat 6.0 released with Mac OS X v10.7 in correspondence with Yahoo Messenger. In addition, I will finally keep compatibility with the software by correspondence to plug in made in a third party in other プロコトル [7].
