macOS Ventura and USB/Thunderbolt Device Security

macOS Ventura and USB/Thunderbolt Device Security

We encourage all CalDigit users to upgrade their Macs to macOS 13 Ventura for the best possible experience. This new OS version has resolved small compatibility issues with external devices, and offers a better user experience, especially for people connecting docks to their Macs.

Starting from macOS 13, Ventura, Apple has implemented a new layer of device connection protection on portable Macs with Apple silicon, such as the M1 and M2. Any new USB or Thunderbolt devices require user approval before the device can communicate with macOS for connections wired directly to the USB4/Thunderbolt 4 port. When a new USB or Thunderbolt device is connected to a Mac, the user will be asked to approve the connection from the pop-up window.

If you find your CalDigit dock, storage, or any devices connected directly or indirectly to a CalDigit device are working properly prior to macOS 13, but cannot be recognized by macOS Ventura, please ensure you “allow” the connection when you are asked to approve the connection from the pop-up window.

You can change this security configuration in System Settings -> Privacy & Security -> and scroll down to the “Security” section. The default configuration is “Ask for New Accessories“, you can change this to “Ask Every Time“, “Automatically When Unlocked” or “Always“. Approved USB/Thunderbolt devices can connect to a locked Mac for up to three days.

If you find the external display connected to your Thunderbolt Dock or Hub no longer work properly after updating to Ventura, please try to boot to safe mode, reconnect the dock, and then restart your Mac and boot back to the normal mode. To start up your Mac in safe mode, please follow the steps on Apple’s support article: https://support.apple.com/guide/mac-help/start-up-your-mac-in-safe-mode-mh21245/mac

Please turn off “Variable Refresh Rate” (VRR) or Adaptive Sync such as G-Sync or FreeSync feature from your external display’s OSD menu (on-screen display) if your display is flickering under Ventura.
