New operating systems add amazing new features and security to our world but that can often come at the cost of compatibility with our current software and drivers, many of which are vital pieces to a studio or DJ setup. While software and hardware drivers can be updated to account for the changes in a new operating system, this is not always immediate. To prevent any downtime waiting for an update, it's much easier check the compatibility of your gear before making the jump. This article is a list of all macOS High Sierra and iOS 11 compatible Numark hardware, as well as what you'll need to know before updating.
Please be aware, Serato has released a statement requesting users to hold off on upgrading to macOS High Sierra until they can confirm compatibility, If Serato is your main DJ software, please do not update your OS until compatibility is confirmed.
