Received my new MBP today and love it! I cleaned up my late 2003 Mac Pro before I used migration assistant and assumed that migration assistant wouldn't migrate anything that could not be used without Rosetta. Wrong! I've been deleting really old stuff like a 2002 version of OmniGraffle that I missed and it subsequently was moved over, but I'm starting to worry that I may be deleting something I need. For instance, there was a Airport set up assistant that said it was for Graphite and Snow, but when I tried to open it I received a message saying that it wouldn't work with this version of OS X. I have duplicate iPod updater software and multiple versions of some other utilities. 1. If the file has a last modified date of 2005 or earlier is it safe to say that it isn't needed/won't work well? 2. Are there programs that are essential to the OS that require Rosetta? I don't have it installed yet. 3. Is there anywhere that lists what applications and utilities should be on a new 2010 MBP as standard? I really don't want to erase and start over if at all possible. And, yes, I have searched using MRoogle and Google, and haven't found anything recent. Thank you!
