trying to upgrade frimware (as recommended) on RS6400. I have two macs. one running el capitan and one running sierra. I downloaded the file clicked on it and then:
There is no application set to open the document “R6400-V1.0.1.24_1.0.18.chk”.

You don't want an application to open the ".chk" file. You want to use the router's Web interface to "Upload" that file to the router. If your R6400 is like my D7000, then ADVANCED > Administration > Firmware Update should get you to the page where you can "Browse..." for that file (in your Downloads folder, perhaps?), and the Upload button should do the rest.
I use Firefox. I'm guessing that you use Safari. With Firefox, when you download a ".zip" archive (like the R6400 firmware kit), it saves the ".zip" archive, which you then need to unpack explicitly. I gather that Safari typically extracts the contents of the ".zip" archive, and saves them. In this case, that's the ".chk" file (which is what you want to send to the router) and the Release Notes (.html) file (which is usually not very informative, but it does offer instructions).
