Hi all, Is there any software/settings which I could install on all my Mac computers (mostly on El capitan and yosemite). So when they tried to copy files to a thumb drive/hard disk or even print out, it will watermark my company's logo in all documents (PDF, DOC, DOCX, PPT, PPTX, XLS, XLSX, images, etc). I have seen a company doing it, but not sure what he used. I know for sure, he's using a mac. Any idea what software he used? I don't really know him. Note: We do store files in google drive and dropbox. A bit concern people leaking our company files. If leaked out, would prefer to show watermark or best even the person's mac name on the document itself. Any help? Thanks.
