Years of Thunderbolt dock wake failures ended with a new monitor, unexplained (fabiensanglard.net)
Sanglard tried two CalDigit docks three years apart, on both a MacBook Pro and a ThinkPad, plus a Thunderbolt 4 certification that explicitly mandates reliable wake-from-sleep. None of it worked. What finally fixed it was replacing the monitor, not the dock, and he still can't explain the mechanism.
In the thread, dozens of readers reported the identical bug across Anker, HP, Dell, OWC and Lenovo hardware — and one found a $20 used Lenovo dock, after a firmware update, more reliable than a $400 CalDigit.
