Thunderbolt Dock Sleep Mode related issues (System Crash & Drives Disconnect) under macOS 12+

When using Apple Silicon Macs with Thunderbolt 4 docks such as the TS4, you may experience one of the following issues:

  • A system crash or kernel panic when using macOS 12.0 to 12.2.1.
  • Your Thunderbolt SSD or USB devices connected to the Thunderbolt dock are constantly ejecting themselves after waking up from sleep mode.
  • The Ethernet connection on the Thunderbolt dock is constantly missing after waking up from sleep mode.
  • Your Mac’s Thunderbolt port becomes unresponsive where none of the Thunderbolt devices or USB devices connected to that Thunderbolt port can be detected.
 
Please update to the latest macOS Ventura and update your TS4’s Thunderbolt firmware to version 39.x or above.
