When to Do It:

  • When a system crash occurs at startup, particularly while the Welcome to Macintosh (Mac OS) screen (or alternate custom startup screen) is visible. Typically, the crash occurs at exactly the same point (such as just after a certain icon appears along the bottom of the screen) each time you start up.

  • When a startup extension does not load at startup, even if the startup sequence otherwise proceeds normally.

  • When a system error or other disruption occurs while you are using a specific system extension or control panel.

  • When a specific command or function in a given application does not work, possibly resulting in a system error. This problem can have numerous causes, a startup extension conflict being one of them. A startup extension conflict can be the cause even if the problem appears unrelated to the functioning of the startup extension.

  • When a problem occurs in similar situations across several or all applications, such as when you are trying to save a document. Again, this type of symptom has many possible causes besides problems with startup extensions.

  • Whenever a message appears at startup (from system software or other startup utilities) that indicates that a likely startup extension conflict occurred during your previous startup.

  • Just about any other time something isn't working as expected. Startup extension conflicts are one of the most common sources of Macintosh problems.
