Determining Whether a Binary Is Universal

You can determine whether an application has a universal binary by looking at the Kind entry in the General section of the Info window for the application (see Figure 1-3). To open the Info window, click the application icon and press Cmd-I.

On an Intel-based Macintosh computer, when you double-click an application that doesn’t have an executable for the native architecture, it might launch. Whether or not it launches depends on how compatible the application is with Rosetta. For more information, see “Rosetta.”
