iChat is an instant messaging software application developed by Apple. It allows users to communicate with each other using text, audio, or video chat over the Internet.
iChat is an instant messaging and video conferencing application developed by Apple Inc. It was first released in 2002 for macOS as a replacement for Apple's previous IM application, Ichat AV.
Some key features of iChat include:
iChat makes use of Apple's Bonjour zero-configuration networking to automatically detect contacts on the local network. It also integrates with macOS's Address Book to allow users to quickly message their contacts.
Over the years, Apple replaced iChat with more full-featured apps like Messages and FaceTime. But for a time, iChat set the standard for easy and integrated messaging and video chat on the Mac.
