Keywords are missing in my Aperture Library after I updated to Aperture 3 (3.5.1) from Aperture 2 back in 2014. In the process of that update I had to do a restore from my Vault to attempt to locate missing photos (with the guidance of a Apple Support specialist. See my forum post 9. 2014.) My Aperture Library lay dormant for quite awhile and I recently discovered this issue when trying to use to search for images. So much work lost as I always key worded on importing. Now I need to update OS from 10.9.5 to EL Capitan. (Much needed!) And then will update Aperture to 3.6.
Any tips for restoring Keywords before I update OS? I searched forums but did not find this. Did I miss it? My Library has 30K + images. I have found keywords on a few batches of iphone photos that were reinstalled after restoring my Library during the update of Aperture and loading on my new Macbook Pro back in 2014. Everything else is missing keywords but the rest of the added metadata is still there (captions are there!)
