iPhoto ’11 9.3
Apple has released iPhoto ’11 9.3, which brings tighter integration between the consumer photo management app and the more professionally geared Aperture via a new unified library. In line with the latest release of Aperture (see “Aperture 3.3,” 12 June 2012), you can now share libraries between iPhoto and Aperture, thus sharing images, Faces, Places, slideshows, and albums. The update also adds support for the AVCHD video format, preserves keywords and titles in exported files with embedded GPS location data, adds flagging capability when in Magnify (1-up) view, and automatically expands the Description field as needed when typing
text. It also brings a new Export option that enables you to organize exported photos into subfolders by event. Note that iPhoto 9.3 now requires Mac OS X 10.7.4 — these changes aren’t available to users running 10.6 Snow Leopard, and for anyone who may still be upgrading from iPhoto 5 or earlier, Apple also released the iPhoto Library Upgrader tool, which also runs only in Lion. ($14.99 new from the Mac App Store, free update through Software Update or the Mac App Store, 630.4 MB via Software Update or 599.65 MB via Apple’s support page)
They also changed the sidebar front in 9.3 from Lucida Grande, the normal OS X system font, to Helvetica. It's a little jarring and doesn't look very Apple-y, especially since it's not nearly as heavy. Helvetica is always nice, but in this context it looks a little cheap and round, I'd say.
"Note that iPhoto 9.3 now requires Mac OS X 10.7.4" I am running Mac OSX 10.6.8. So why does the App Store tell me I have an update available (and then refuse to download it)?
Because the App Store is a little stupid, compared to Software Update, which knows you can't run it. :-) Those who got iPhoto before the Mac App Store aren't even offered the update in Snow Leopard.
