You may be unable to participate in a video or audio chat in Mac OS X 10.5 Leopard on PowerPC-based Macs that have an 867Mhz G4 processor. The iChat Video menu may not appear, and under the Connection Doctor's Capabilities tab your computer may be listed as "unable to participate in a video conference" due to bandwidth/network issues.

You may also receive an alert when you attempt to respond to a video conference such as:

Ask the other participant to try the following steps one at a time while you are still connected. After each step, it may be necessary to speak for a few seconds to test whether or not the change helped.

   When authenticating to a Mac OS X Server version 10.5 iChat server that is bound to Active Directory, clients that are not configured to use Kerberos will not be able to authenticate, when using Active Directory credentials.

   Products affected

   • Mac OS X Server 10.5

   
   Solution

   Either configure the iChat client to use Kerberos authentication or disable the use of CRAM-MD5 authentication on the iChat server.

It works much like a "green screen" used by actors in a Hollywood studio.

   This works by taking a snapshot of the background when you are not chatting. Since the computer knows what the background is, parts of it can be replaced with images or movies. Since you were not part of the background when the snapshot happened, you will not be ignored, hence you or ]]> Fri, 26 Oct 2007 07:12:49 -0500 Release date: Thu, 5 Jul 2007 18:59:33 -0500 http://docs.info.apple.com/article.html?artnum=305830 iChat can communicate with cellular phone systems using SMS (Short Message Service). SMS is a global wireless service for sending messages (up to 160 alphanumeric characters) between mobile subscribers and external systems such as email, paging, and voicemail systems.

   With iChat, you can send messages to .Mac and AIM users, as well as cellular phone users. Note: You must be signed in to iChat with a .Mac or AIM account to do this (not Jabber or Bonjour).

      Contact the manufacturer of your third-party USB camera if you have questions about UVC compliance.

      Icons of buddies on your iChat Buddy List may sometimes appear as a blue globe, white square, or appear with no icon. This can happen with both AIM- and .Mac-based accounts.
      
      

      

      Products affected

      • iChat

      
      Solution

      Server issues on the AIM network can cause this issue. If you are affected, contact America Online for more information.

      Note that text, audio, and video chats will still work--this issue affects icon appearance only.

      • Your computer's capabilities
      • Buddy's computer's capabilities
      • Available bandwidth

      If you have buddies in your buddy list that don't meet the requirements for mutil-way conferencing, they won't appear in your Buddy List with a multi-way icon. Similarly, if your computer and bandwidth do not meet the requirements to host and/or participate in a multi-way conference, you will not appear in others' Buddy Lists as capable of doing so.

      What can I expect while this is happening?

This can happen when chatting via voice or video with a buddy from your AIM, Bonjour, or Jabber buddy lists.
        Solution: Close the chat window, or quit iChat, to stop transmitting audio or video to your buddy.

If there are any upper case letters, the iChat service may not start.

        If the iChat service will not start and any iChat host domains contain one or more upper case letters, follow these steps:

        1. Launch Server Admin.
        2. Select the appropriate server under Computers & Services.
        3. Select the iChat service.
        4. Click the Settings tab.
        5. Change any upper case letters in the Host Domains field to lower case letters.
        6. Click the Save button.
