Hi,
An @Mac.com name is a valid AOL/AIM Screen Name.
Any Issues and the AIM servers will say the AOL/AIM name or password is incorrect.
As I said earlier, there can be issues if when you create an @Mac.com or even a MobileMe account Apple lets you create passwords of up to 20 characters (I think).
The issues is the AIM Server can check the name with Apple but don't parse Passwords that have more then 16 characters (You have to change the Password to 16 characters or less).
There is also another issue.
Creating a Name at the @Mac.com page allows you to use spaces as valid characters (As In
ralph johns@mac.com) but again the AIM servers cannot parse these names as Spaces are not Valid at AIM
Use
iForgot to check the name. You can also change passwords via this.
Use the On Line option and answer the security questions.
That should confirm whether the account/Screen Name/Apple ID works.
Then go to this page
https://settings.aim.com/
Use the Sign In option top right.
Enter your @mac.com name and password (It will read AOL at the next page to do that)
If it works properly then you should be returned to the page I linked you to but it will now have your Screen Name showing above the menu area.
This will confirm that the @Mac.com name is accepted as a AIM Screen Name.
If you are still having issues, go to the iChat Menu > Preferences > Accounts
In the Account Info tab make sure you are logged out (Deselect "Use this Account")
Go to the Server settings tab
Change the port from 5190 to 443 (it may also pay to deselect SSL)
Log back in again.
Deleting
com.apple.ichat.AIM.plist may help.
If the issue is an incorrect password you may need to delete the entry from the KeyChain (Use KeyChain Access in the Applications/Utilities folder)
Hope this helps.
