DJ Software platforms DEX 3 and RED Mobile 3 do not yet support the new MAC OS X El Capitan update.
At this time PCDJ does not recommend updating to El Capitan on your gig machine. Our DJ software development team is currently investigating reports of in-app menus not displaying correctly and reported audio issues. We’ve also been informed quite a few DJ controllers are not yet working 100% with the El Capitan.
Our developed team is working diligently to ensure stability with OS X El Capitan soon. Version 3.5 for both RED Mobile 3 and DEX 3 mixing software versions will address the non-displayed menu and potential audio issues. We plan to launch the 3.5 updates later this month.
If you have already updated to El Capitan and are experiencing these or any other issues, please CONTACT THE PCDJ SUPPORT TEAM
