Renamed folders on MacBook Pro remains untitled.

Somebody should be able to help you with that, but we will need additional details:

• Where exactly is the source folder located
• Where is the destination folder located?
• What exactly does the error message say?

@FishingAddict asks some very pertinent questions. Another one is how are you renaming them? And moving them.....your thread title mentions moving, but the question never mentions "moving".
