Installing the driver

web site (https://teac.jp/jp/language), and download the Mac
Driver.
Unzip the downloaded file, then open "TEAC USB HS Audio
KEXT Install Package xxxxx.pkg" (xxxxx is the driver version) in
the extracted folder.
A warning window that says "TEAC USB HS Audio KEXT Install Package xxxx
cannot be opened because it is from an unidentied developer." may appear.
If it appears, hold the Control key and right click, then choose "Open" from the
menu, and click "Open" to continue with the installation.
Follow the instructions to proceed with the installation.
Your user name and password will be required to proceed

Choose "Restart" when the installation completes.
In this step, the following message may appear.
If it appears, click "OK" to restart.
If you are installing the driver on a system that uses macOS High Sierra,
follow steps 5 to 7, otherwise, jump to step 8.
After restart, open "Security and Privacy" in System Preferences.
Click "Allow" in the "General" tab.
If "Allow" is disabled and grayed out, click the Lock icon [ ]
to allow the setting to be changed.
You can then enter the password you used in step 3.
If the blocked driver is TEAC USB HS Audio alone, it shows “Legacy
Developer: Teac”.
This setting change MUST be carried out within 30 minutes
of the driver being installed.
