Hi, I'm still using my old workhorse Mac Pro 2,1, and the original keyboard and mouse have had it. I replaced them with a full size Magic Keyboard and Magic Mouse. The mouse works perfect, but the keyboard is only like 98% there. With a few key mappings I was able to get it to adjust my brightness, but there doesn't appear to be anything I can do about the function keys for sound. This system has a modern WiFi/Bluetooth adapter (out of a 2015 iMac) installed, and supports continuity and AirDrop. Is there any way I can get these key mappings working? Kext hack? Just a setting I'm blatantly missing? Thanks in advance!
