It's not a surprise [1], but anyway very frustrating. Regards, Ralf [1] Technical Support Today at 17:08 Hi, I am very sorry for the misunderstanding. Please understand that Support Ticket Requests are for technical assistance with supported systems and the PreSonus product line. I am very sorry but I cannot facilitate communication with engineer or developers. If you require contact with another department, you may submit a request here. http://www.presonus.com/about/contact-us Please understand that "supported" means what is stated for the System Requirements on our product pages. http://www.presonus.com/products/AudioBox-1818VSL/tech-specs Yes, Apple OSX is of course included in this support. I am sorry that I did not mention it previously. It was simple mistake. Yes, Linux very well may work, however, Linux is "open source", therefore we cannot assist you with this entirely. I am very sorry, I do not mean to argue semantics. I am only trying to help as I can. If my assistance is not what you need, then I can only offer my apologies. I may only be able to provide you with some general suggestions or alternatives that may or may not help regarding the function or non function of your AudioBox itself. If you haven't already, you might consider reaching out to the User Forums for the AudioBox and even for Linux. https://forums.presonus.com/viewforum.php?f=165 ======================= All that said, how may I assist you with the AudioBox 1818 ? Please state your concern and issue plainly and we will address it to the best of our ability. Thank you for your patience and understanding as we all work to help.

It's a pity that "open source" isn't supported. However, actually iOS isn't "open source" and Apple tablets are as much used for audio, as other Apple computers.
