Which command can you run to start querying the kext policies on a macOS?

The command that allows you to start querying the kext (kernel extension) policies on a macOS is the one that utilizes sqlite3 to access the KextPolicy database directly. This database maintains the records of loaded kernel extensions, their status, and associated policies. By using sqlite3 followed by the path to the KextPolicy database, you can execute specific queries to retrieve detailed information about kernel extension policies, such as whether they are permitted or blocked.

This approach provides direct access to the database, allowing for more nuanced and powerful querying capabilities compared to other commands. The sqlite3 command enables users to formulate SQL queries, which allows for flexible data extraction rather than just listing loaded kernel extensions or other functions.

The other options do not provide the same level of detailed querying capabilities. For instance, while using cat to view KextPolicy may seem like a valid option, it merely displays the contents of the file without the ability to perform specific queries. Similarly, kextstat lists currently loaded kernel extensions but does not provide policy-related information, and launchctl list gives a list of currently running services rather than serving as a tool for querying kernel extension policies.
