Usb PC pad controller or thrustmaster common ground

looking for a pad again for PC. anyone know if this pad has common ground?

does it work with mac?

also anyone know any pad that has common ground that works with mac OSX
also anyone has any other recommendation post it please.

I know that the gamestick for xbox360 has common ground, but I have a hard time making that work.

I also know (through recommendation) that this pad has common ground.

reason I’m not getting that is because I’m really looking for something that has at least 9 buttons.

so anyone has one of those please test it for me. thanks.
