Paths "through" alias files make no sense. Nothing else in the system will resolve an alias there, so nothing will ever produce such a path. If your code is producing such paths, you should fix it, because nothing else will be able to process them.

You should construct NSURL objects from the two paths, use -getResourceValue:forKey:error: with the key NSURLFileResourceIdentifierKey to get the resource ID for each, and then use [resourceID1 isEqual:resourceID2] to determine if the two paths refer to the same file-system object.
