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

This only works if the application has an application bundle; otherwise please see Show Application Title, Version, and Company#Mac OS X and iOS.

    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);

     '''// 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);
