Mac permission issues and Isilon OneFS 7.1.0.6

Is there a known permission issue with Mac OSX 10.9 or any version and OneFS 7.1..0.6?  We upgraded the Isilon clusters from OneFS 7.1.0.5 to 7.1.0.6.  Every since I have had users that use Macs complain that when they copy and paste files within the same parent folder to another child folder the files that they paste loose permissions.
