TAC-2/TAC-2R: macOS operating issues and workaround

Recently a problem has occurred where Mac reboots itself (kernel panic) in the following combination when it is connected to TAC-2/TAC-2R Thunderbolt® audio interfaces.

  • macOS sierra 10.12.4 or later
  • After returning from sleep mode


We are still analyzing this problem, however the following workaround may be effective:

  • Unplug the Thunderbolt® cable from TAC-2/2R before Mac is turned to sleep mode or shutdown.

* Please connect the cable with TAC-2/2R again after turning on the power or returning from sleep mode.


Please check back for updates on this issue. We apologize for any inconvenience.
