Previously, Focusrite has issued drivers for USB devices on older Mac operating systems, however
we would now recommend not installing any drivers that you might find online or on old CD installer
discs when using one of our USB interfaces on Mac computers.
If you happen to install an old Focusrite driver by mistake then this could cause a number of issues,
including:
- Glitchy audio
- Your device appearing only as an input device with no outputs available
To remove any potentially problematic drivers you may have installed, you can run our Class
Compliant application, which is attached at the bottom of this article.
Alternatively, you can manually delete drivers by going to Finder > click 'Go' at the top of the screen
> select 'Computer' > Mac HD > System > Library > Extensions. In this folder, remove any files
named 'FocusriteUSB2Audio.kext' and then restart the computer.
