For those who want to show the Application Title, Version, and Company for an application on the Mac, this can be done using the following method:

CODE FOR SHOWING APPLICATION TITLE, VERSION, AND COMPANY 
 uses MacOSAll, CarbonProc, StrUtils;

 var
   BundleID: String;
   BundleName: String;
   BundleRef: CFBundleRef;
   BundleVer: String;
   CompanyName: String;
   KeyRef: CFStringRef;
   ValueRef: CFTypeRef;

 function GetInfoPlistString(const KeyName : string) : string;
 begin
   try
     Result := ;
     BundleRef := CFBundleGetMainBundle;
     if BundleRef = nil then Exit;  {Executable not in an app bundle?}
     KeyRef := CFStringCreateWithPascalString(nil,KeyName,kCFStringEncodingUTF8);
     ValueRef := CFBundleGetValueForInfoDictionaryKey(BundleRef, KeyRef);
     if CFGetTypeID(ValueRef) <> CFStringGetTypeID then Exit;  {Value not a string?}
     Result := CFStringToStr(ValueRef);
   except
   on E : Exception do
     ShowMessage(E.Message);
   end;
   FreeCFString(KeyRef);
 end;

 procedure TForm1.FormCreate(Sender: TObject);
 begin
    try
      Form1.Caption := 'About '+Application.Title;
      StaticTextAppTitle.Caption := Application.Title;
      BundleID := GetInfoPlistString('CFBundleIdentifier');
      // CompanyName is presumed to be in the form of: com.Company.AppName
      CompanyName := AnsiMidStr(BundleID,AnsiPos('.',BundleID)+1,Length(BundleID));
      CompanyName := AnsiMidStr(CompanyName,0,AnsiPos('.',CompanyName)-1);
      BundleVer := GetInfoPlistString('CFBundleVersion');
      StaticTextAppVer.Caption := Application.Title+' version '+BundleVer;
      StaticTextCompany.Caption := CompanyName;
    except
    on E : Exception do
           ShowMessage(E.Message);
    end;
 end;
