I need to use a binary file to automatically open a file. I have a program in my /usr/bin/ directory and I would like all files with the .fir extension to be opened by this program. The usual "right-click" and open with other application method simply doesn't work. I figured out a way to look at the /usr/bin/ directory but I cannot select any of the binaries. Using Mac OS X 10.8 I am wondering how I can make this happen. Is it even possible? Please let me know!
