X600 mixer is not on the “supported” or “not supported” list in this article: http://denondj.com/kb/article/2167, can we get a clarification?
Thanks for posting.
As the compatibility list says, “if you do not see your product listed in this article, it is not officially supported for use with macOS Sierra or does not require compatibility such as headphones, speakers and accessories.”
I hope this clarifies things. Let me know if you have any additional questions.
