Unfortunately, fileAttributesAtPath:traverseLink: is deprecated. The replacement given is attributesOfItemAtPath:error:, which doesn’t traverse symlinks. However, the documentation claims that this behavior is not guaranteed, and may change in a future version of OS X. Sadly, there does not seem to be a non-deprecated replacement for fileAttributesAtPath:traverseLink: which has guaranteed behavior.

The best thing to do is probably to use POSIX calls such as lstat().
