I'm unable to use any of the function keys (brightness, microphone, sound etc). I'm running Mojave on a Late-2013 27" iMac.

Any ideas?

iMac 27″, macOS 10.14

Is this a new Magic Keyboard? They require a Mac running macOS 11.3 and a Late-2014 or newer iMac.

Yes, it's a new one. Unfortunately, my Mac isn't. :(

Do the function keys work if the charging cable is plugged in?

My iMac is too old to connect the cable. Basically, my iMac is incompatible with the keyboard (so I’m realizing).
