Question

Hello everyone,
I recently upgraded my Macbook pro late 2014 to its latest update macOS Sierra v 10.12.1

Is an i7 2.2hz 16gb 15 "

When I started my vsl1818 for a project the screen went black and I left a mistake which told me that I had to restore system, finally I gave the problem and update my Presonus VSL, but I could only put Universal Control.

In the section Audio Settings and midi lets me use STEREO, 2.0, 5.1, 7.1 or headphones, but not a stereo and helmets at a time. 

When I open a project in Reaper or any DAW I can choose several outputs and if you let me listen ST + headphones. But if I do not enter a daw no.

I need to solve the problem because I work in live and I need to throw tracks from itunes or similar.

Hope-ho can solve the problem
regards
Isaac Salvador.

VSL is not supported under OSX 10.11.x and 10.12.x

Use this article to fully remove any previously installed VSL drivers.

Then download and install the current device drivers.

Once installed, connect your AudioBox to your computer and power it on.  Open the Universal Control from Applications.  Update Firmware if prompted.

Test again.
