I have the old LR version 5 on my PC. Works well and I can download my RAW files from SD card reader taken on Nikon D750. When I try on new iMac it says it does not recognise the format. Am I missing a step??
Please make sure that you have Lightroom updated to the latest version 5.7.1 on the Mac computer.
As the camera is supported in Lightroom 5.7 and above.
