I am having trouble importing/converting Sony RX100 IV ARW files into Lightroom 5 on my MAC. How do you do this?
You can't import that camera RAW files directly. LR 5.x.x does not support that camera and never will.
You will need to use the most current version of the free Adobe DNG converter program to convert those ARW files into DNG files.
Or upgrade to LR 6 or the CC version with a subscription to the Photographers plan.
It worked with Adobe DNG converter program. Thanks BE
