Hi,
A MacBook is an Intel.
Currently my MacBook Pro in the Activity Monitor, with All Processes selected, shows that all items that are open or used by the OS are in fact Intel (I was sure Firefox would return Power PC). When I launch my 2001 version of Word it does say Power PC in the Activity Monitor.
If iChat is showing Power PC go to the Applications Folder.
Click once on iChat to Highlight then use the Apple Key and "I" Key together (Get Info)
This should open a Window that may fill the left hand side of your Screen depending on what reveal Triangles are in use.
Make sure the General section is viewable/open and check that iChat is not set to "
Open Using Rosetta" (Some iChat add-ons that may not have been updated may require this).
Above this check box make sure the version is at 4.0.5 if you are at OS 10.5.4
If you have no iChat Add-Ons that are not Intel ready then uncheck the Rosetta check box.
