I wrote before but I can't find it.
I have photoshop CS6 and I can't open NEF files from my Nikon D3 or my Nikon D7000 every time I tried the PS crashed even if I tried to open the files from Bridge or directly in PS.
I have a MAC PRO 2
Processor 2 x 2.66 GHz Dual-Core Intel Xeon
Memory 5 GB 667 MHz DDR2 FB-DIMM
Graphics NVIDIA GeForce 7300 GT 256 MB
Software Mac OS X Lion 10.7.4 (11E53)
Thank you very much for the help
