Apple no longer has aperture as their photo editing program, which I have used since it came out. How do I now get my Aperture library into Lightroom?
In Plug-in Extras in the File menu, there's an Aperture import plugin.
If you're on Lightroom 5, check this out: Aperture import plugin now available
The plugin is part of LR6/CC, but there's good information there on using it.
