I have been trying to find answers on this and have so far been out of luck. I used Aperture 3 up until it was no longer supported last year. Prior to investing into Photoshop & Lightroom, I migrated copies of my Aperture and Photos libraries to an external HD with a backup copy on my AirPort. The libraries show as two different photos libraries on my external HD and they show the correct file sizes for what I copied over. When I attempt to use Aperture or iPhoto plug-in in LRC, it says that those libraries are not the correct type for the plug in. Any advice on how to pull these photos into LRC?
I am using LRC Release 10.0 and am running MacOS v. 10.15.6. I appreciate any help or advice, I'm relatively new to LRC and Photoshop.
