Nikon software ineptitude
Nikon has posted a warning on its web site about Snow Leopard compatibility.
Note that Nikon makes no promises about fixing anything, only that “more compatibility information” will eventually be posted. It’s the “deer in the headlights” approach.
One reader sums it up better than I could:
Way to plan ahead, Nikon! Never mind that developer builds of SL have been available to your software developers for more than a year.
BTW, god help you if you use a Nikon Coolscan. They haven't updated Nikon Scan since 10.1, yet they're still selling selling the scanners!
