The move to restrict USB-C devices by default is a tacit nod to an evolving range of threats that pose a risk to Apple users. Apple says that accessories that are already connected will automatically work when updating to the new macOS software.

Apple says this doesn’t apply to power adapters, standalone displays and connections to an approved hub - and devices can still charge even if you don’t approve the accessory. A new security feature in Apple’s upcoming macOS 13 Ventura will automatically block new USB-C devices from communicating with the operating system until the accessory can be approved by the user.Īpple dropped details of the new security feature in its release notes, which appears to be aimed at protecting newer Apple laptops that run its bespoke M1 or M2 chips from potentially malicious accessories.Īccording to Apple’s description, the feature will be enabled by default and will require the user to approve a USB-C accessory before it can talk to the operating system - essentially an on-screen pop-up asking the user for permission.
