What type of information can customers choose to send to Apple for diagnostics?

Customers can choose to send diagnostic and usage information collected anonymously to Apple for diagnostics. This type of information helps Apple improve its products and services without compromising user privacy. By sending anonymous diagnostic data, customers contribute to the overall enhancement of the software and hardware, allowing Apple to identify trends and issues that may affect performance. Anonymity ensures that personal identifiable information is not linked to the data sent, addressing privacy concerns while still providing valuable insights into device functionality and performance.

The other options do not align with Apple's approach to user privacy and data handling. Sending only personal identifiable information would risk privacy violations, while sharing all running applications data or detailed error logs of all crashes could expose sensitive personal data and exceed what is necessary for diagnostic purposes. Apple emphasizes a balance between collecting useful information and protecting user privacy.
