Smaart IO Isn't Working Properly in macOS 10.11.4

If you are having problems with Smaart interacting with your Smaart IO, and you are running macOS version 10.11.4 or newer, you are likely experiencing a problem with the recent OS update.

In the 10.11.4 macOS update, the Smaart IO is renamed internally to "Smaart I_O", which breaks the communication between the Smaart IO and Smaart. You can verify this if the device is named "Smaart I_O" in Audio/MIDI Setup.

To resolve the problem, perform the following steps:

• Open up the Smaart IO Control App
• Click Options -> Options
• Select your Smaart IO device 
• Click "Rename"
• Name the device "Smaart IO"
• Save your changes
• Power cycle the interface by unplugging it, waiting a few seconds, and plugging it back in

This should resolve any issues you are having with the Smaart IO due to the macOS update. This change only needs to be performed once and will persist even after closing Smaart and restarting your computer.
