Copying Files to the Ready for Submission Folder in Mac OS X
There is a known issue copying files directly from your personal computer to the Ready for Submission folder when using a Mac OS X machine. To resolve the issue, first copy the file to the Working folder then move the file to the Ready for Submission folder.
If you are having trouble moving from the Working folder to the Ready for Submission folder, see the helpful tip below. For background reference, this limit is caused by the inability of the Mac OS to resolve highly granular permissions on a Microsoft Windows-based file server using Active Directory.
