In this article, we explain the installation process for Control 2 software, as well as updating the Symphony I/O MkII via Thunderbolt
There are a few new steps when installing this new version of Control 2 for Symphony I/O MkII Thunderbolt users compared to the previous Control software.
If you have Dante, and just need to update your firmware, check this article instead: Updating Symphony MkII firmware via Dante
Install Control 2 Native:
First, you'll want to run the included UN-installer. This will uninstall all Apogee software to ensure you have a clean install.
If you had the previous "Symphony Control" software installed, then please follow these important steps EXACTLY:
- Unplug the Thunderbolt cable between the Symphony and computer.
- Restart the computer
- When the computer is running again, open the Control 2 software download and run the UNINstaller app that is inside.
When Uninstall is complete, RESTART your computer.
Do not skip the uninstall step!
If the previous Symphony Control software isn't uninstalled, it can cause conflicts with the new Control 2 which uses DEXT instead of KEXT.

Next, run the Installer.
During the install process, enable the "Support for Symphony I/O MkII" at this step:
You'll be prompted for your computer password, to allow the installer to modify files, and to restart.
Click Allow:
After you restart, you'll get a prompt that an extension needs approved:
Click the option to Open System Settings and Approve the Apogee Extension. You'll be prompted for your computer password again. This is what installs the DEXT.
On some systems, an additional step is needed.
In System Settings, go to General > Login Items & Extensions.
Scroll down to the Driver Extensions section and click the i button on the right
Toggle the ApogeeTBTDextInstaller.app to the ON position, then click Done.
Update Symphony I/O MkII Thunderbolt Firmware:
Head to Applications > Utilities and find the Symphony updater:
Select Thunderbolt only:
Follow the prompts until the firmware update is complete.
After that, you should be good to go!
