Upgrading the Aperture Library
To use an existing Library with Aperture 1.5, you must upgrade it. Aperture prompts
you with the following dialog:
By default, previews are created for images in the Library. Previews are built in the
background after the Library is upgraded to version 1.5. Regardless of what you choose
here, it is easy to switch the setting in Aperture later. You can control this preview
setting individually for each Aperture Library on your system. For more information
about turning off previews after an upgrade and selectively building them, see
“
Example Workflows for Using Previews Effectively
If you have a Library with thousands of images, it will take many hours to build these
previews. In that case, you may wish to build the previews overnight or when the
computer is not in use. Or, you can deselect the “Create previews for existing images“
checkbox and build previews on a project-by-project basis, as discussed in “
Workflows for Using Previews Effectively

apply to all Libraries.
To open Aperture preferences:
m
Choose Aperture > Preferences.
Select “Create previews
