MacOS Ventura can be reassuring if you’re worried that compromised peripherals will ruin your computer. According to The Verge, Apple has revealed that Ventura will require user permission before USB-C and Thunderbolt accessories can transfer data to M1 and M2-based Macs. You will not be afraid that someone can deliver malware simply by plugging in a flash drive, or that a poorly designed product can destroy your machine by sending bad information.
This policy is enabled by default, but will not affect the accessories included with your Mac during the operating system upgrade process. In addition, it will not block external monitors, power adapters or products connected to already approved hubs. Devices will also continue to charge, even if they are blocked, so you can still use your computer to charge a friend’s phone.
This will not prevent devices that can fry the ports from electric shocks. However, this can add a meaningful layer of security to the USB-C requirement for encrypted authentication certificates. You will have the last word on data access and you can simply stop a malicious device before it has a chance to cause damage.
