Help - my daughter has a 15-inch MacBook Pro released October 2011, it runs Lion 10.7.3. A friend gave her a Maxtor OneTouch 4 Mini to use as a backup hard drive. She used the CD to install the software and it didn't get very far before the error window popped up "you can't open the application NotificationExec because PowerPC applications are no longer supported". Then that message continued to pop up every 10 seconds, almost like a viral message. She deleted everything that had installed and emptied the trash bin but it continues to pop up. She has called Apple AND Seagate support and they have been no help. She can still use the computer, access internet, etc., but this window keeps popping up. She is away at college so I'm just trying to help out - any suggestions, ideas?
