Just curious if you drag a folder from the Mac finder into that area where crates are meant to be does it create a crate out of the folder.
Make a test folder on your desktop with a just a couple of tracks
I’ll check it out later and see what I can find. I’m not sure if there is any issues on my end but I don’t use Engine Prime often enough. I generally leave the tracks on the Hardware.
@Anthony_DDJ Thank you so much. I actually got through to someone earlier today on the Denon Technical support team. They have set up an appointment to do a screen share with me on Thursday. I’ll keep you posted on how it goes. I have faith that they will resolve the problem.
Kind regards
Ravi.
Hopefully the screen share session will help torn anything out. Both left and right click add a playlist here so hopefully all goes well.
Same here, all works like it should. I can’t reproduce the issue.
Quick update
Just got off the phone from a very helpful guy named Matt one of the Denon support techs. He was very patient and went through all the privacy setting and it looks like something i one of the privacy tabs was preventing me from creating the playlists. Not 100% sure but once he’d done the settings it’s all working fine now!
Thanks you so much to everyone here for all your support 
Great to hear, that You have it sorted out with Denon dj support. I wish You happy mixing!
Thank you so much
