I have an issue where InDesign CS6 will not package a file on a Mac running 10.6.8 and will generate the following error message: "Cannot copy necessary font(s)". I have tried packing this same exact file onto another Mac running 10.6.8 and no error messages were generated and the InDesign file packaged properly. Both versions of InDesign CS6 are the exact same (8.0.1). I can't figure out why one machine will package the file and the other one won't. I am saving the file with the exact same name and saving to the desktop on each Mac. Please help!
