Currently having issue updating firmware on my Nikon D7100 DSLR. The problem is with the updated Lens Distortion upgrade (2.009 on Nikon USA site). I was able to download the camera firmware update, not issue. But, the lens distortion fails every time I attempt it with a message saying there is no software in the download. I have Macbook Pro with OS X 10.11.2 installed. I was on the phone with Nikon for about an hour this morning and they have no idea what the issue is. Was considering calling Apple Care,as this laptop is only about month old, but thought I'd give the forum a shot first. Here is the page I am working from on the download......http://downloadcenter.nikonimglib.com/en/download/fw/140.html Any help is appreciated, Thx.
