A customer was using Windows and we've switched them to Macs. All perfect. But! There seems to be no way of preventing two machines from accessing the same file at the same time. In Windows, Excel would say "this file is already opened on another machine" or something to that effect. The Macs simply open the file(s) and whoever saves last wins. This, of course, is a no-go.
How can I prevent a second Mac from opening a file that is already open on a first Mac? I'm stumped. I don't think the solution can be to tell them to call each other to ask whether a file is already opened somewhere...
