I found an Adobe article mentioning the Aperture import plugin, but can't find it where Adobe links to:
Anyone know if this is still available or not?
The plugin is included in LR CC 2015 / 6. Look in the File > Plug-in Extras menu. If you don't see it, do File > Plug-in Manager, scroll to Aperture/iPhoto Importer Plug-in, and click Enable if the plug-in isn't enabled.
Thanks John! Forgot about the plugin manager, I found it.
