The update can collect diagnostic and usage information from your Mac and send it to Apple for analysis automatically. The information is only collected with your explicit consent, and is submitted anonymously to Apple. the company insists. Apple explains you can choose to send these reports automatically or manually if one of these diagnostic 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

Diagnostic and usage reports may include the following information:

* Details about application or system not responding, application unexpectedly quitting, 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)

Apple adds all reports 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 reports by adding additional comments describing your actions when the issue occurred.
