Share analytics information from your Mac with Apple
Analytics information may be sent to Apple when you report a problem; you can opt in or out of sharing the information.
About analytics and privacy
With your permission, macOS can automatically collect analytics information from your Mac and send it to Apple to help improve the quality and performance of its products. This information is sent only with your consent and is submitted anonymously to Apple.
Further details
If you agree to send Mac analytics information to Apple, it may include the following:
Details about app or system crashes, freezes or kernel panics
Information about events on your Mac (for example, whether a certain function such as waking your Mac was successful or not)
Usage information (for example, data about how you use Apple and third-party software, hardware and services)
Analytics data contains your computer’s hardware and software specifications, including information about devices connected to your Mac and the versions of the operating system and apps you’re using on your Mac. Personal data is either not logged at all in the reports generated by your Mac, is subject to privacy preserving techniques such as differential privacy, or is removed from any reports before they’re sent to Apple. If you want to add a description of your actions when the problem occurred, click the arrow 
and enter your comments. Please do not provide personal information.
Data can be sent automatically if one of these events occurs:
An app quits unexpectedly
You choose to force an app to quit
A system error occurs that causes your Mac to restart, or requires you to restart your Mac
If you agree, we may share your crash data with 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 analytics information that is relevant to that partner’s or developer’s software, hardware and/or services, as long as the information is in a form that does not personally identify you.
If you agree to send analytics information to Apple from multiple devices that use the same iCloud account, we may correlate some usage data about Apple apps across those devices by syncing using end-to-end encryption. We do this in a manner that does not identify you to Apple.
Information is sent to Apple using your Internet connection. If your Mac is not connected to the Internet, the data is saved and sent the next time you connect to the Internet.
Your Mac keeps analytics information for one month after it is generated, then deletes the information.
