How Can I Set Up iChat in Tiger?

Hi, I'm not sure icloud account works with 10.4.11, but you can get a free AOL/AIM account that will work...

Creating a new AIM ID

If your system cannot be upgraded to OS X 10.7.2 or later, you can create a new AIM ID to use with your current version of OS X by following these steps:

1. Create a new AIM ID from the AOL website.
2. Add this new account to iChat by following the instructions in this article.
3. After setting up your AIM account in iChat, Open iChat preferences.
4. Click the Accounts button in the preferences window, then select your new AIM account from the list of accounts.
5. Click the Server Settings tab and make sure that the option to use SSL is selected for your new AIM account.
6. Close the iChat preferences window.
7. Creating a new Apple ID requires you to re-add your buddies to your new buddy list. Re-add your buddies to your by following the instructions in this article.
8. Remove your old mac.com account from iChat preferences.

OS X: Using me.com or mac.com IDs with AIM in iChat requires OS X v10.7.2 or later - Apple Support

Here there are only 3 choices in iChat in 10.4.11... .mac, which will not accept a .icloud entry, AIM, which works, & Jabber which I'm not sure how to setup.

I have no need for an AOL account either, other than to make iChat connections in older OSX versions. 🙂
