I have a 2013 Macbook Pro with Adobe Lightroom 3 installed and use this for editing raw photos I take with my Nikon D7000 camera.
I havent done this for a while but when I try to import to LR a current picture in raw format it cant import it and gives me the following error: The file is from a camera which is not recognized by the raw format supported in Lightroom. (1) When I then click OK the window closes or if I click check for updates it cannot update stating "The version check was unsuccessful". I get that the Db was changed in a 3.x update that makes things not backward compatible but why cant i open my own files and edit them? Any help is appreciated. Thank you!
You can try updating, but it might not work since Apple made huge changes to the macOS including not being able to run 32 bit software and i believe Lightroom 3 software uses 32 bit installers even though the Lightroom application itself is 64 bits.
