Quantum Thunderbolt series devices require our driver to function on macOS.
Quantum USB has a custom low-latency driver that outperforms the standard built-in driver.
Both of these drivers are included in the Universal Control app.
Important Note: You will need to have your computer set to Reduced Security.

After installing and opening Universal Control, you will be prompted to "Approve the Audio Driver System Extension".
The operating system will give you the choice of "OK" or "Open Security Preferences".
Choose "Open Security Preferences" or if you have already clicked "Ok" open System Preferences>Privacy and Security. Once this is allowed, your Quantum will sync to the computer.
Pre-UC 3.6: If you cannot sync after installing UC, run the uninstaller located in the same folder as the UC installer. After the uninstaller has finished, reboot the computer and run the installer. You will now be prompted again to approve the installation.
UC 3.6 forward: The Quantum driver has changed to a driver extension. If you cannot sync after installing UC, drag the UC application from the Application folder to the Trash. You'll be prompted about removing system extensions. Once the extension is removed, run the installer for UC and follow the prompts.
To manually uninstall, please follow these steps.
