Some users have reported experiencing audio glitches and drop outs with the Scarlett range of interfaces since updating to OS X 10.9 Mavericks. If you are experiencing these problems with your interface, it is possible to utilise Apple’s USB audio driver by downloading and running the class compliant mode application as a workaround while Focusrite investigates the issue.
