These iChat 3 pages are coloured Orange and have the iChat 3 icon on them that was in use at the time, so you know where you are. The icon differs from Version 1 by having the camera logo added and from iChat 2 by having the Running Man removed.
iChat 3 and iChat 4 Specific Start Up info
Kit and Differences
I will dispense with the colour codings on this page that I have used on other pages.
You may also want to refer to the main info on Setting up iChat
Differences in the Start Up Screens
In iChat 3 and 4 we have the ability to use Jabber IDs as well as AIM valid ones. As you may already know, iChat was first an AIM client with Apple getting AIM to recognize the then .mac names of email@example.com format, as well as allowing AIM names to be used and now allows the MobileMe format of firstname.lastname@example.org. As far as the Start Up Screens go it means there is and extra page on the way through the Set up Procedure.
At this point all screen names except for Mac ones have to be gained in advance which almost certainly means registering a name somewhere.
Names and Where to Get Them
With regard to Jabber valid names, this includes a GoogleMail ID as this is a valid name with GoogeTalk which is a Jabber server run by Google. You can also get them from Public Jabber Servers or in fact an iChat Server in OS X Server which is also a Jabber Server.
Jabber is somewhat different to AIM in that individual servers are based all over the place. They are linked over the internet so you can talk to other Jabber Buddies. Some of these servers are Public and anyone can register. They can also be Private (In-house in large organizations usually). Being Private means you can not register a Name from the outside, but you will still be able to chat to Buddies that have private IDs.
Jabber uses the XMPP Protocols and this site has the most extensive list of Public Servers. Your Name, or ID as it tends to be referred to, is normally in the format of username@jabberservername.(com). Not all end in .com which is why it is in brackets. As you can see from the list you can pick almost anywhere by country to somewhat identify yourself. Some of these servers allow you to register via a web browser (Like getting an Mac ID or an AIM one). Others require you use a 3rd Party Jabber capable IM application such as AdiumX or Psi. These can search for Jabber Servers or you can type them in to register with a particular one.
Once you have an ID you can enter it in the box in the pic above. It is possible to set it up later.
At this point I am using a coloured box to highlight something.
In iChat 3 using a GoogleMail ID in the box in the Start up pages does create a problem with iChat 3. iChat presumes the ending of the email type name will be the server to contact as the Host to Login to. It will presume that, from your ID of email@example.com, that the server is googlemail.com. This is not the case.
This means going to the iChat Preferences (iChat Menu > Preferences) and then the Accounts section and then the Server Settings tab and changing the server name (talk.google.com) and port (5223) used to Login.
See the pics here for further info.
This is corrected in iChat 4 which gives you an option similar to the Split between AIM and Mac names.
So.... You may have already done some background preparation in getting both an AIM valid Screen Name and a Jabber one.
You can now Run iChat for the first time and enter the info in the Text fields on the various Screens. In the case of the Jabber ID you have to tick the box to enable it as well as entering in info.
If you do not have all the info ready when you run iChat for the first time it is no problem as you can Set up more accounts in iChat at a later stage.
If you have used Screen Names in another app and have them in your Card in the Address Book some of the Info will be prefilled in the text fields due to the close links between the Address Book and iChat.
The Kit: iChat 3
As you will have guessed iChat 3 will need a higher spec machine.
This though does not exclude the original spec Macs from using the non multi-chat features.
To remind you a G3/600Mhz or above can use the Video and Audio features in iChat 2.
iChat 3 is about being able to do up to 4 way chats in a Video chat (you and three Buddies) or a 10 way Audio Chat (9 others plus you).
Anything less than a G4/1Ghz or G4/800Mhz Dual Processor Mac is not going to be able to join a 4 way Video chat (read that as anything over 1-1 Video.)
Anything less than a G4/1Ghz Dual Processor is not going to be able to be Host or Initiate to a 4 way Video chat.
There are considerations on what connection speed both up and down you have from the Internet. For more in the form of tables see this Apple Article: HT1771
This leads us on to Audio Chats particularly with up to 10 people and hosting them. As you can see from the first table on that page, to Host/Initiate you need more than a Dial-up internet connection, although you can join in other ones if you only have Dial-up.
The Kit: iChat 4
For everyday 4 way Video or 10 way Audio chats litle has changed for iChat 4 compared to iChat 3. See this Apple Article: HT2020. What has changed is what you can do regarding the Add-on features of Video Effects and Backdrops.
In iChat 4 several things were added. Amounst these were Screen Sharing using an Apple Remote Desktop like ability and Photo Booth type Effects and "Green Screen" Backdrops.
Click to Open - More on Effects and Backdrops
To see some of what I am am talking about visit ChatFX's site. This works in iChat 3 up to the 10.4.10 update. The page I have linked you to shows a changing sample of the options this Add-On has.
Apple added the features used in PhotoBooth and the same floating pallet with forward and backward buttons to display "pages" of Effects and Backdrops.
This pic is from my G4/1Ghz Dual that can only display the Effects and not the Backdrops. To get the Backdrops you have to have an Intel Processor.
Mousing over the arrows expands then to say how many "pages" there are. As default from Apple you have two pages of Effects and two pages of Backdrops.
As you can see here there are options to add User Specified items into some of the back drops.
I was using the same camera via a DV converter over firewire to input to my MacBook Pro to get this view. The Number of pages tells you that I have extras added to the default ones from Apple. These can be Still pics or Movies.
Therefore Intels are needed to do Backdrops where as a suitably spec'ed PPC Mac can do Effects only.
