Hello all,
I'm currently helping a client manually combine and manage two very old aperture libraries into a single Lightroom classic catalog. The combining task is complete. I'm now attempting to find duplicates via Teekesselchen. I've installed Lightroom Classic v10.2 and installed the Teekesselchen plugin by placing it on the desktop and enabling the Plug-In under the Plug-in manager but cannot seem to get it to appear under Plugin-Extras.
At first I created the catalog on a Late 2013 iMac, running macOS 10.15 and have since moved the entire catalog and photos to another computer where it will reside going forward, being a 2020 iMac running macOS 11.2.3. Both machines are running Lightroom classic v10.2. The catalog is functioning fine on the new computer otherwise, however I cannot squash this issue. I'm getting the same issue after I decided to open and test the catalog on the old iMac, I can install and enable the plugin via the Plug-in manager but cannot make it appear under Plug-in Extras there either. Is there something simple I'm missing or is this an issue? Any advice would greatly be appreciated thank you!
