Hello,
NX1 and 5K IMAC as do i. i have this NX1 on order, hoping to get great 4K video into my IMAC, but it seems you aren't having luck with the IMAC and this for video files? What about the playback on the IMAC once you have the video files uploaded? That http://www.wondershare.com/mac-video-converter-ultimate/ programe might be needed? I'm not interested in video editing, just want to store the files and watch them. Is this a bad combo NX1 and 5K IMAC? I ordered my IMAC with the better video card and maxed out memory. If you have some time, please give me a shout 248 396 6359 markb@rad.hfh.edu
