Yeah, whatever you're using to capture input doesn't seem to work on macs. Same experience here.
I'll look into this! Hopefully it's something that can be fixed without resorting to buying a mac myself lol
The input capture uses Unity's built-in system, so I'm a little confused if it's not working (it's something I would think they would have working across platforms). Are you using any kind of keyboard layout or system language that's not US English?
