    • Native Mac OS X

    • Classic

    • Java

    • BSD/X11

    NOTE

    For more information about the Classic environment, see Appendix C, "The Classic Environment."


  • A process is a running program.

  • Each process on Mac OS X runs in its own protected memory space.

  • Classic runs in a single process called TruBlueEnvironment, but Classic applications do not use protected memory and can crash other Classic applications.

  • Mac OS X includes functionality to assist users with difficulties seeing, hearing, and using the keyboard and mouse, enabled from Universal Access preferences. Enabling Universal Access functionality works for all applications in Mac OS X.

  • There are many approaches and tools to help troubleshoot issues with applications on Mac OS X:

  • System Profiler provides a list of all applications located in Applications.

  • If an application does not respond to input from the keyboard or mouse, choose Apple > Force Quit or press Command-Option-Esc to open the Force Quit Applications window. Select the application to quit, and click Force Quit. You can also use the Dock or Activity Monitor to force quit an application.

  • If a Mac OS X application is not running correctly, it might be due to a corrupted preference or cache file. Safe Launch makes it easier to identify and replace corrupt preferences files, but some applications may not support Safe Launch.
