Operation of a MR816* connected via an Apple MD464 Thunderbolt to FireWire Adapter
(1) If an Apple Mac computer not equipped with a FireWire port (i.e., a Retina MacBook Pro, MacBook Air or iMac) is started up without the Thunderbolt to FireWire Adapter connected, a "Failed to initialize" error message will be displayed by the Yamaha Steinberg Firewire driver. However, the computer will operate normally in such a case.
(2) To prevent the above message from being displayed, connect the Thunderbolt to FireWire Adapter before starting up the computer.
(3) If the Thunderbolt to FireWire Adapter is disconnected without first powering down the Mac computer, the computer has to be restarted to transfer audio data again. The driver does not detect the removal and a re-connection of the adapter and using the Yamaha Steinberg FW Driver won't be possible until a system reboot.
*MR816 firmware version 1.10.
**Operation has been confirmed under test conditions; however, this does not guarantee correct operation in all conceivable situations. Yamaha/Steinberg can accept no liability whatsoever for damages of any kind resulting from use.
