I have a huge Aperture 3 library that will not open, giving the following message:
Verify that you have iPhoto 9.4 or later. Then open the library in iPhoto to upgrade it..
It is not set as my default Aperture library, so every time I try to access the first aid tools via option + control during launch dose only show the first aid options for the default library.
How can I open the external library with the first aid options?
