I've just come across from Windows xp to a Mac with 10.6. I have hundreds of NEF's on an external HD that appears to be formatted to FAT32. I had a box version of NX that came with my D300 but have since bought a D700 so have to buy the UPGRADE version on NX2..
Ive loaded both NX and NX2 on the mac without problems.. NX2 launches super fast. The problems start when I attempt to open a NEF file. It will pop up ok but then hangs and says it's updating.. That's when a little beach ball cursor pops up..
I then have to force quit the program.. Ive tried hitting the update button but it tells me there's no updates available.. On launch NX2 says its version 2.0..
