WARNING - PreSonus this time
I was just going to post the section on the AudioBox VSL series, but haven't seen this mentioned here yet, so, here's the entire email.
==================================
Dear PreSonus Customer
Apple OS X 10.11 is about to be released. Before you update, we wanted to make you aware of some compatibility issues that may occur with your PreSonus hardware and software.
StudioLive 16.4.2AI, 24.4.2AI, 32.4.2AI, RM16AI, and RM32AI: Smaart is not functioning in OS X 10.11.0. This appears to be an Apple issue as it is functioning in the current beta of 10.11.1. If you use an AI-Series or RM-Series mixer and rely on Smaart, we advise you to wait to update your OS until this issue is resolved.
Classic (non-AI) StudioLive 16.0.2, 16.4.2, 24.4.2 mixers, FireStudio Mobile, FireStudio Project: Universal Control version 1.7.2 or lower will not function correctly on OS X 10.11.1.
You must update to Version 1.7.3 which is already available for download in your
my.presonus.com account.
AudioBox 22VSL, 44VSL, 1818VSL: Starting with OS X 10.11, Apple has restricted kernel level mixing access for third party vendors. This means that VSL software will no longer function on Mac operating systems beyond version 10.10. On OS X version 10.11 or higher, AudioBox VSL devices will only operate as class-complaint audio interfaces. Please
refer to this article here that explains the issue in more detail and how to resolve it.
If you currently do not use VSL software, your AudioBox VSL interface will continue to function as you expect.
All PreSonus customers: We have tested Studio One 2.6.5, Notion 4.0, and higher versions. These products are compatible with OS X 10.11. That said, we have seen notifications from other vendors including Native Instruments that there are also 10.11 compatibility issues with some of their products.
To avoid any issues, we strongly advise you to check with all of your hardware and software providers before updating to OS X 10.11. Please click here for our full, up to date compatibility statement for Mac OS X 10.11Thank you for being a PreSonus customer!
