How do I create a CD that opens a "Drag this icon to the Application folder to install" on the Mac and autoruns an installer on Windows?
You can use hdiutil
eg.
hdiutil makehybrid -o [output-file] [input-folder] -iso -hfs -hide-iso [mac-only-file] -hide-hfs [windows-only-files]
What you will want to do is hide the windows specific files from the HFS partition and hide the Mac only files from the ISO.
Then you would use an autorun file as your normally would on Windows.
On the Mac side there are many applications you can buy for creating a Finder window that looks a certain way but all these changes can be made within finder. You then will need to copy the DS_Store file to the CD and finder will automatically apply any changes that you have made.
Also using -hfs-openfolder will cause it to open automatically when inserted on the mac.
Jordan Brough has a really good write-up on his blog about this:

For what it's worth, this was the first result returned from a fairly simple google search...
