Description sandra pazos 2018-07-17 10:41:50 EDT 
The Key variable should not always be assigned to 0. 
To solve a problem with a specific platform, you should enclose it in the corresponding define. The code below maybe fix the problem: 
procedure TTeeGrid.KeyDown(var Key: Word; var KeyChar: WideChar; Shift: TShiftState);
var tmp : TKeyState;
begin
  inherited;

  tmp.KeyChar:=KeyChar;
  tmp.Key:=Key;

  tmp.Shift:=Shift;
  tmp.Event:=TGridKeyEvent.Down;

  FGrid.Key(tmp);

  {$IFDEF MACOS32}
  Key:=0; // <-- disable "beep" on Mac OSX
  {$ENDIF}
end;
