Pioneer DJ does not recommend using any beta OS as there may be unexpected performance issues with software or drivers. We do not support unreleased OS's and typically begin testing of our products once the final public release is available to ensure that there are no last-minute changes between the beta and public versions (as has occurred in past). As such, there may be a delay between the public launch of an OS and official support as we validate our products.
Thank you for your support and understanding.
