" An error occurred when attempting to change models " is the warning window i always get when i open lightroom every time now from a catalog file or the app it self or while switching from a catalog to another. i can't access anything ( library, import, ....)
i'm using OS X El capitan and started to face errors since then. How can i fix that?
Here is a workaround of the issues with Lightroom and El capitan : http://blogs.adobe.com/lightroomjournal/2015/10/update-on-lightroom-2015-2-lightroom-6-2-r elease.html
