TOpenDialog在Mac上不起作用

Question

我在XE3中有一个非常简单的测试应用程序，带有一个按钮，一个标签和一个TOpenDialog。 这是整个代码，有一种匹配的形式：

unit Main;

interface

uses
  System.SysUtils, System.Types, System.UITypes, System.Rtti, System.Classes,
  System.Variants, FMX.Types, FMX.Controls, FMX.Forms, FMX.Dialogs;

type
  TForm1 = class(TForm)
    Button1: TButton;
    Label1: TLabel;
    OpenDialog1: TOpenDialog;
    procedure Button1Click(Sender: TObject);
  private
    { Private declarations }
  public
    { Public declarations }
  end;

var
  Form1: TForm1;

implementation

{$R *.fmx}

procedure TForm1.Button1Click(Sender: TObject);
begin
     if OpenDialog1.Execute
      then begin
           Label1.Text:= OpenDialog1.FileName;
      end;
end;

end.

当我在调试下运行并单击Mac上的按钮时，该按钮保持按下状态（蓝色），但没有对话框出现，并且出现“无聊的沙滩球”或Mac上的应用程序崩溃。 我已经重启了Mac几次，但是并没有任何改善。

更新：我已经更新了XCode，修补了OSX，重新建立了连接，刷新了本地文件，但仍然无法正常工作。

我从Mac获得崩溃日志：
