According to Apple, macOS 13 Ventura will automatically block new USB-C devices from communicating with the OS until the user approves the accessory
As described in Apple's release notes, the new security feature protects Apple laptops running its M1 or M2 chips from potentially malicious accessories.
A USB-C accessory will need to be approved by the user before it can communicate with the operating system according to Apple's description - essentially a pop-up asking for permission.
Apple says that this doesn't apply to power adapters, standalone displays, and connected hubs - so devices can still be charged even if they don't have an approved accessory. When the new macOS software is updated, accessories that are already connected should automatically work.
Apple's move to restrict USB-C devices by default is a tacit acknowledgment of a growing number of threats that pose a threat to iOS users.
According to researchers, malicious implants can be hidden in regular charging cables. These implants can be used to hijack computers or permanently damage the innards of laptops.
It is nearly identical to Apple's USB Restricted Mode in iOS 12, which prevents unauthorized accessories and cables from accessing the data on iPhones and iPads without the owner's permission.
At a time when law enforcement was using phone-cracking devices to circumvent Apple's security measures, this new macOS feature is almost identical.
