What does this have to do with Adobe InDesign?
If you want to restore your preferences, a Mac plist file is not how to do it. Follow these instructions:
?I want to change my ID plist. We did this when we upgraded and ID quit freezing and closing.

Try the method described in the link above. InDesign doesn't store its major preferences in a plist. While other Mac apps may do this, Adobe InDesign does not.
