Can't import images from Mac Photos v1.0.1 to Lightroom 6 even after installing aperture_iphoto_importer_plugin3. Error states "The importer plug-in supports libraries maintained with iPhoto 9.5.1 and later. An older library is currently selected. Please note that errors may be encountered if you proceed." Why does it keep thinking it is an older version of Photos? extremely frustrating
The Aperture plugin you trying use its basically use to import images from IPhoto Or Aperture to Lightroom. As of now there's no plugin available which can import your Images from Photos v1.0.1 to Lightroom.
What else you can try:-
Open the Photos v1.0.1
select all the Images using the edit menu.
Export to the specific folder saved on your system using file menu.
then Import your Image from there to Lightroom.
