For some reason, Apple has disabled any current TB3 devices with 1st-generation USB-C chipsets from Texas Instruments from working in their latest OS revision, as found on the new MB models. Only devices with the 2nd-generation chipset that is newly available and soon to be replacing the 1st-gen model, will be functional unless Apple rolls back the lockout. Because the chipset is still at the end of it's first-run development and certification testing, don't expect any replacement products for anything that is a paperweight until next year.
