I purchased lightroom 5 sometime back to install on multiple platforms. Recently did an update on my macbook and it was able to read the NEF files from D750.
However when I installed lightroom 5 on my iMac, the prog keeps hanging when I attempt to import files from the D750. Other NEF files from my D700 were ok.
Anyone knows why?
Could be a hardware issue
Make sure the cable connection to the D750 is properly connected. Also, if possible try using a card reader. Or vice versa.
