Curious if anyone tested BETA 2 with a Mac running the latest version of Catalina and Apple Music. BETA 1 never worked for me and I had to go back to using my windows PC with iTunes.

Catalina is an osx so disappointing (rotten) that I would not even dare to test it and install it (it’s the equivalent to Yosemite to say besides Apple blocked the possibility of leaving reviews on the appstore not to be dismantled, the version may be finally drinkable in the final version … business to follow !!! Mojave is so much better

I accidentally updated to Catalina back in October - iTunes became Apple Music. Since then I haven’t been able to use it with the Engine software. Beta 1 kept crashing on me. I’m hoping I have better luck with Beta 2.

I was just reading the release notes of the Engine Prime Public beta #1 and it mentions support for Catalina OSX and Apple Music. Weren’t these persistent issues I read of here meant to get sorted in beta 1…or are they going to have it sorted out in beta 2? In regards to the EP public beta 1 release notes and now reading these comments on this post isn’t it any wonder im still reluctant to update to Catalina and use Apple Music.

I just finished trying the Beta 2 on my Mac with Catalina. It still keeps shutting down the Engine software when I try to sync or drag and drop. I’m done messing with Catalina and Engine. Back to my super slow Windows PC.

I bought a Macbook Pro 16" at Christmas and instantly bootcamped it lwith Windows 10. Haven’t been in the Mac side since. Runs absolutely perfect on Windows

Bootcamp Mac to run windows 10 - interesting. I like this idea - I’m going to try it. Thank you for the tip.

I’m running an iMac with Catalina and Apple Music. I never had a problem with BETA 1 and I’m running BETA 2 now… again, no issues here. I wonder why BETA 1 didn’t work for you.

Interesting. Curious- did you format the Prime4 internal harddrive as exFat? Denon instructions say were should use exFat which works perfectly with Windows. But I’m curious if I change it to Fat32 if this will make a difference.

Yes, I formatted as exFat

Okay finally figured out why my Mac/Catalina kept shutting down after the Beta update. Under Security & Settings - Privacy - files and folders - there is a check box for Engine Prime Beta that needed to be checked. As soon as I checked it - everything worked! Thanks for your help.

If it take 10 to 15 mins to load tracks / collection to a usb drive with the OLD engine. Why wait 1 to 2 hours for this new “gimic” Prime 1.4.0 to load… Can Denon just give us smart creates and STOP with the crap updates!!!

It’s just the same thing as the old Music Management program but “Some how even worse then before”… STOP the trying to fix BPM, Gridding, and all the SUPER DUPER stuff and make ENGINE PRIME a MUSIC MANAGEMENT program FRIST…


cos it’s still beta … ? :roll_eyes:

You SO need TO get YOUR keyboard CAPSLOCK button SORTED out FIRST.

It’s OBVIOUSLY faulty. It KEEPS engaging AND it’s LIKE you’re SHOUTING at US.

Have a look in the suggestions section and if someone has already asked for these smart crates that you’re after, then LIKE their post so that Denon know the idea has got another vote . If the idea isn’t there already in the suggestions section then add it yourself using the supplied form from that section

Not SHOUTING at you troll just Denon​:joy::joy:
