As you have suggested I am posting in this forum.
Since purchasing Aperture Inspector 1.0 from the old MacCreat I have not be able to upgrade past 1.1.
Downloaded your newest version 1.5 however it just would not install. So I decided to just uninstall the older version (1.1) and was able to install 1.5. Did have to first turn off security features in order to install. Seems that Apple does not recognize your software App. No real big deal.
Now my old serial number from MacCreat does not work so I assume I will need to purchase a new one.
The other problem is that after nearly two hours the Inspector is still reading the Aperture Library. There are around 43,000 images in the Library on an external 1TB USB 3 drive and running on a MacBook Pro 15” Retina with 16GB Ram. Is this normal to be taking this long?
