Archived - iTunes 10 for Mac: May quit unexpectedly on launch

Resolution

This issue may occur if you have more than one copy of a QuickTime component found in different folder locations such as in:

System-wide locations:

• /Library/Components/
• /Library/QuickTime

User-specific locations:

• ~/Library/Components
• ~/Library/QuickTime 

  Note: The "~" represents your Home folder.

To resolve this issue, delete the extra copy of the component file in the user-specific folder and not from the system-wide folder.

Some examples of QuickTime component files found to cause iTunes for Mac to quit unexpectedly are:

• /Library/QuickTime/DesktopVideoOut.component
• ~/Library/QuickTime/DesktopVideoOut.component

or 

• /Library/QuickTime/Sonix SN9C201 WebCam.component
• ~/Library/QuickTime/Sonix SN9C201 WebCam.component

Delete the duplicated component file from the user-specific QuickTime folder (~/Library/QuickTime/...)
