This info is for Mac users only. Apple has recently released OS X 10.11, El Capitan. At this time, we recommend that customers using future.dj (pro) postpone their upgrades to 10.11. If you did upgrade already, please note that there is an issue with drop-down boxes in the Preferences window (eg. if you want to choose a different audio device, interface, etc). The current solution is to exit full-screen mode (so future.dj will be in window mode) and then go back to the Preferences. We are working to fix this issue for the next release. If you have any questions, please don’t hesitate to contact us.
