UPDATE: July 21, 2014 - The updated release for Mac OS X and Windows are ready. To download it, please access it through your http://my.presonus.com account. Your AudioBox will need to be registered, through which you will be able to obtain the drivers.
We have discovered that Apple has made a fundamental design change in their latest release of computers including the iMac series 14,1 and 14,2 (late model 2013), Apple MacBook Air 6,2 (late model 2013) MacBook Pro (11,1 - 13"::11,2 - 15" :: 11, 3 - 15 ") (released October 22, 2013) and Mac Pro 6,1 (released late 2013) are incompatible with PreSonus AudioBox VSL-series products. As of January 2014, latest-generation Mac Minis (late 2012, 6,X series) are not affected by this issue.
AudioBox 22VSL & 44VSL: As of the second to last week of April we have learned that the incompatibility issue with USB 3.0 on Mac OS X Mavericks 10.9, 10.9.1, and 10.9.2 late model MacBook Pro, MacBook Air, iMac and Mac Pro systems released in late 2013 is an issue with Apple's USB 3.0 device driver. We have tested and confirmed that this distortion issue is resolved with pre-release builds of 10.9.3.
Unfortunately Apple does not disclose release dates, PreSonus does not know when Apple will release it's next update. Until that time arrives, the AudioBox 22VSL and 44VSL can be used as class-compliant devices by not installing the VSL software, using the settings in your DAW to control your I/O, and using Audio MIDI Setup for advanced configurations.
AudioBox 1818VSL: The aforementioned MacBook Pro, iMac, MacBook Air and Mac Pro models will not work with the AudioBox 1818VSL in either mode with VSL software installed or in class-compliant mode with no VSL software installed. We suggest using a different computer with the AudioBox 1818VSL. Our Engineering Team is actively engaged in fixing this issue and we expect to have an update available in the coming months. We will be delivering frequent updates on the status in our community forum here: https://forums.presonus.com/viewtopic.php?f=165&t=270
We have tested and qualified that all of our other products including software products such as Studio One and Capture along with Hardware products including AudioBox USB, StudioLive 2442, 1642, 1602, StudioLive 32AI, 24AI, 16AI, FireStudio Mobile, FireStudio Project, FaderPort all work with these computers as expected.
