I am a professional photographer and have been using LR since it was released. I borrowed a Sony A7II and took some shots so I could compare images on my Mac. I have 5.7.1 installed but it will still not recognize the arw files. Only shows the jpegs. Any advice? Thanks.
You need Lightroom 6.1.1 or Lightroom CC 2015.1.1
Alternatively, you can download the free Adobe DNG Converter, convert your RAWs to DNG, and then import the DNGs into Lightroom 5.7.1
Downloaded DNG converter 9.1......wouldn't open them.
