Both Pages '09 and Pages '13 use "com.apple.iWork.Pages" as a bundle ID.
I can set individual .pages files to open with Pages '09, but when I try to set all .pages files to open with Pages '09, Pages '13 keeps taking over.†
† Selecting a .pages file, changing to "Pages '09", and then clicking "Change All…" always selects Pages '13. You can see it here https://vimeo.com/78545014.
Anyone know how to force OS X to accept Pages '09 as the default for all .pages files?
