Send diagnostic and usage data to Apple
Apple would like your help improving the quality and performance of its products and services. Mac OS X can automatically collect diagnostic and usage information from your Mac and send it to Apple for analysis. The information is sent only with your consent and is submitted anonymously to Apple.
Diagnostic and usage data may include the following information:
- Details about application or system crashes, freezes, or kernel panics
- Information about events on your computer (for example, whether a certain function, such as waking your computer, was successful or not)
- Usage information (for example, data about how you use Apple and third-party software, hardware, and services)
Diagnostic and usage data will contain your computer’s hardware and software specifications, including information about devices connected to your computer and the versions of the operating system and applications you’re using on your computer. You can enhance diagnostic information by adding additional comments describing your actions when the problem occurred. When the diagnostic dialog appears, simply click the disclosure triangle and enter your comments in the provided field. Please do not provide personal information.
Data can be sent automatically or manually if one of these events occurs:
- An application quits unexpectedly
- You choose to force an application to quit
- A system error occurs that requires you to restart your computer
All diagnostic and usage information is collected and sent to Apple anonymously. None of the information submitted identifies you personally.
Set reporting options
If you encounter an unexpected application termination, must force an application to quit, or are required to restart your computer, you’ll be offered the opportunity to collect information about the problem and send it to Apple.
If you choose to send the data to Apple, you can then specify any one of the reporting options for future information collection:
- Automatic reporting
- No reporting
- Ask each time
Automatic reporting of diagnostic and usage information is off by default, and occurs only if you have given consent.
To select automatic reporting: When prompted, make sure “Don’t ask me again” is selected, and then click OK.
After you click OK, automatic reporting of diagnostic and usage information begins, and information is periodically sent to Apple anonymously. You will not be prompted again unless you deselect “Send diagnostic & usage data to Apple” in the Privacy pane of Security & Privacy preferences.
To select no reporting: When prompted, make sure “Don’t ask me again” is selected, and then click No Thanks. No information is sent to Apple.
To select ask each time: When prompted, deselect “Don’t ask me again.” You then have the option to agree or disagree each time a diagnostic event described above occurs.
How diagnostic and usage reporting works
All diagnostic and usage information is collected and sent to Apple anonymously. None of the information sent to Apple identifies you personally.
To enable Apple’s partners and third party developers to improve their software, hardware and services designed for use with Apple products, Apple may also provide such partners and third party developers with a subset of diagnostic information that is relevant to that partner’s or developer’s software, hardware and/or services, as long as the diagnostic information is in a form that does not personally identify you.
Information is sent to Apple using your Internet connection. If your computer is not connected to the Internet, the data is saved and sent the next time you connect to the Internet.
Your Mac keeps diagnostic and usage information for one month after it is generated, and then deletes the information.
Opt-out of automatic reporting
You can change your reporting options at any time:
1. Choose Apple >System Preferences, click Security & Privacy, and then click Privacy.
Open the Privacy pane of Security & Privacy preferences
2. Deselect “Send diagnostic and usage data to Apple.” Diagnostic and usage information will no longer be sent to Apple.
View diagnostic and usage information
You can use the Console application to view diagnostic and usage information sent to Apple.
1. Open Console (located in the Utilities folder of the Launchpad).
2. In the Console toolbar, click Show Log List.
3. Click the disclosure triangle next to “Diagnostic and Usage Information” to show this section.
Console shows diagnostic and usage information even if you did not select to send reports automatically.
SubmitDiagInfo entries indicate when diagnostic and usage information was sent to Apple.
If you are logged in as an administrator user, you can view any item in the section. If you are not logged in as an administrator, you can only view User Diagnostic Reports. For security purposes, certain system diagnostic and usage information is sent only when an administrator is logged in.
