Adobe recently released Camera Raw 9.5 with support for the Canon EOS-1D X Mark II, 80D, T6, Nikon D5 & D500. Unfortunately, if you're using OS X 10.7 or 10.8, you'll want to hold off on installing the update.
From Adobe:
Camera Raw 9.5We have a critical issue with support on OSX 10.7 and OSX 10.8. Please continue using Camera Raw 9.4 until we issue an update that resolves the issue.
