Test macOS sierra MR816 doesn't work

Just install the MR Tools. IF you need the other FW driver install you will know as your MR wont work. At that point just uninstall the driver and load up the newest FW driver. I think they changed the driver as well to the current one and didnt tell anyone

Where are these MR Tools. On a CD or something that I threw away 4 years ago?

Come on man
