We have come to an issue in preparing a section of the new FAQ and I need a Mac user to clarify this...

When moving a runtime from an unpacking folder to a runtime folder, Does the MAC OS prompt the user to merge, overwrite, (anything) the new runtime folder with the old one?

On a Windows box, the OS asks if you want to merge the new folder with the old one of the same name. This is what we want. Is this the case with a MAC? If not, what messages do you get and what are the right answers to give?

Any help appreciated.
