In Mac OS 10.10.3, Apple introduced Photos, a replacement application for iPhoto and Aperture. We want to make you aware that if you upgrade your iPhoto library to Photos you will no longer be able to select your images from the Media section of the Open dialog in Freeway and Showcase, nor will you see your iPhoto or Photos libraries in the Media selection area at the top right of the window in Showcase.
Exhibeo - our companion gallery-creation application for Freeway and successor to Showcase—displays your Photos image library if you click on “Photos” under the “Media” heading in the sidebar of a new Finder window.
