According to The information provided by the Verge notes, Apple has disclosed that Ventura will need their user permission before the USB-C and Thunderbolt appliances can transfer data on M1- and M2-based Macs. People won’t have to worry that someone could simply transmit malware by plugging in a drive or that a poorly-designed input might destroy their device by delivering bad data.
The policy is facilitated by default, but it won’t affect appliances plugged into your Mac when the OS upgrade process is persistent. It is also not supposed to obstruct external monitors, power adapters, or products connected to the already ratified hubs. Devices will continue to charge even after being blocked so that one can still use their computer to top up a colleague’s phone.
This feature is not supposed to undermine the devices that can fry ports through electrical waves. However, this could add a meaningful sheet of security to the USB-C’s provision for encrypted authentication certificates. One will have the final choice on data access, which might just stop a harmful device from causing any damage.
