I have a Mac, i have had light room for some years, currently Lightroom 5 , i have just purchased a new Nikon D500 only to find i cannot download pics into Lightroom.Am up to date with computer updates and Lightroom updates.
The Nikon D500 requires Lightroom version 6.5, your options are
a. Upgrade to LR 6 or
b. Download the latest DNG Converter from Adobe (its free), the latest version is 9.6.1. Then use the converter to convert the .nef raw files to the DNG format. This will allow you to import the .dng files with LR 5.
Info about the dng format can be obtained at the link below.
Thank you i will try that. Nick Bell
