Note: iTunes Diagnostics is used to gather and display information about your computer—it does not resolve issues itself. You can use the information provided in the diagnostics to troubleshoot an issue you may be having, but you may need to follow specific steps in a related article or have assistance from an Apple Advisor to resolve an issue.
To run iTunes Diagnostics:
- Install the latest version of iTunes.
- Open iTunes and choose Help > Run Diagnostics.

- Run through each of the selected tests. As you complete each test, you may see links to various support articles to help you resolve any issues you may be experiencing.
When all tests are finished, a summary will be displayed which you can copy to your clipboard or save to your computer. You can save the results to your computer or send them to Apple.
To save to your computer:
Click the Save button. Choose where to save the files on your computer, and click Save. This saves 2 files in the location specified called "iTunes Diagnostics.RTF" and "iTunes Diagnostics.SPX".
