I have an app which will be for Mac and Win, and maybe Linux down the

Both Mac and Win provide common folders for reading data:
Mac /HD/System Folder/Application Support
Win C:/Documents and Settings/All Users/Application Data
...but in my testing here only users with admin privileges can write
to those folders. :(
What is the OS-recommended place to store common data which can be
written by any user?
I had exactly the same problem with a currently-shipping app. I'm
writing app-specific data to the two folders you mention above. The
only way we could work around it was to wrap our app in an OS-approved
installer and have the installer set the permissions for our
application support folder to allow access by everyone. The app
support/app data folders don't need their permissions reset; only your
own standalone-specific folder has to be set. For Mac OS X, we used
Apple's package installer. On Windows, most any installer will do this
for you.
Thanks for the input, Jacque.
But now I wonder: Is there a way to do this from within a custom
Rev-based installer? How does one trigger the OS X authentication dialog?
Well, that's the deal. I couldn't find a way to do that without using
Apple's installer. Most users wouldn't trust a home-made dialog that
asks for their admin password; they want to see the "official" one.
Ergo, package installer time.
Our app is a very simple one-file thing that can easily be dragged to
the Applications folder. The only reason we needed an installer was for
the writable permissions problem. I have to admit though, it does lend a
great deal of professionality when you use an OS-native installer.
People trust your stuff more.
