I have Lightroom_5_LS11_mac_5_7_1-3.dmg What must I do to make it compatible with the RAW files from my Canon EOS 5DSR?
Same question for photoshop.
A dmg file Is an installer file for the Mac if I'm not mistaken. But regardless, you need Lightroom 6 or Camera Raw 9.0 as the bare minimum to have support for your camera. If you have Photoshop CS6 then you can install Camera Raw 9.1. That will give you support for the camera. But you will have to purchase an upgrade in order to have support in Lightroom. The alternative would be for you to download the DNG converter and use it to create DNG copies that you can use in the version of Photoshop and Lightroom that you have now.
The 5DSR was first supported in Camera Raw 9.0 (only compatible with Photoshop CS6 and Cloud versions) and Lightroom 6/CC.
