Apple sent an email to Aperture customers today to reminder them about the impending removal of the professional grade photo editing software from the Mac App Store. The email confirms that Aperture will be removed from the Mac App Store when the release of Photos for OS X. When Photos for OS X launches this spring, Aperture will no longer be available for purchase from the Mac App Store. You can continue to use Aperture on OS X Yosemite, but you will not be able to buy additional copies of the app. You can migrate your Aperture library to Photos for OS X, including your photos, adjustments, albums, and keywords. After migrating, your Aperture library remains intact. However, Aperture and Photos do not share a unified library, so any changes made after the migration will not be shared between the apps.
Aperture users will be able to continue using the software on OS X Yosemite after its discontinued. Aperture users can migrate their photo libraries to Photos for OS X, including photos, adjustments, albums and keywords.
Photos for OS X will be available this spring for OS X Yosemite.
