Sound Issues withSince installing macOS High Sierra 10.13.2 Update

https://serato.com/forum/discussion/1662298

I have Mac OS X High Sierra and I did that exact update (10.13.2) but then on my MacBook Pro (Mid-2012) and Serato DJ 1.9.10 , I normally have my Latency set to 5ms on my Denon DJ MC7000 I was having terrible yellow or red USB Buffer light on the top right and my audio was breaking up so bad that even switching my Latency higher barely fix the problem. So for sh*ts and giggles installed Serato DJ Pro (Beta) and I did not had that problem. But what I ended up doing is doing clean install of High Sierra 10.13.1 but not install that Update (10.13.2) I will wait until Apple addresses that supposeably 3rd Party USB Audio fix with next update or wait until Serato DJ Pro comes out.

It’s not the original High Sierra version that’s the issue for the MC 7000 but the 10.13.2. I was able to roll back to version 10.13.1 and the sound quality issues went away.

My guess is you will have to contact Denon and/or Serato and see if updates are available. You could of course roll back to the version that worked using your Time Machine backup.

I have both a Pioneer DDJ SX2 & the Denon MC7000. I use Serato DJ with both. I upgraded both my laptops to High Sierra after seeing that Denon said it was now supported as well as hearing the same from Serato & Pioneer. After playing for 15-20 minutes on the Denon the sound starts to distort badly. Once I reboot the Denon it goes away but again comes back after a short time. I did an extensive test at home it reacted the same with both laptops with the Denon. I tried changing USB ports, checking for latest serato versions to no avail. I did the same exact testing with the Pioneer and NO issues at all. I did a full gig with the Pioneer and it worked as it should with no problem. Obviously whatever testing Denon did with High Sierra was flawed in my opinion. Hopefully they'll get this straightened out quickly as the Denon MC 7000 is an awesome machine and I prefer using it over the Pioneer.

Hello, I have the same sound issues via Reloop RMX90-DVS. It seems that is Serato bug in 10.13.2 :-/

It does it in latest Serato 1.9.10 or 1.9.8 too.

I installed the firmware yesterday and ran my MC7000 for a few hours on auto play on a Mac with OS 10.13.2 installed. No issues with sound quality after the update.

Sounds good. I am irritated, however, that is still written on the Denon website 10.13.2 does not work.

But, the Denon support has also written me that they have solved the problem.

I think I will try again next weekend with 10.13.2.

If there are still problems, please report here again! Thank you!

Hello Chris, I have the same problem with my MC7000 after the update to 10.13.2. Unfortunately I did not do a Time Machine backup with version 10.13.1. Does Apple offer another solution to recover the computer?

Now I’ve got downgrade to 13.1 with a timemachine backup and I must stop my gig yesterday. The system was totally crashed and the sound distorded horribly. So let me know if you have better ideas. I changed to a 2015 Mac with usb and there was still the same problem.

No chance to play actually with the Denon and the new system. Tomorrow I will speak with Apple support and the must help me. 3 Gigs crashed with my stupid system paid for 4000 euro!!!

I do not believe it !!! Last week I was still at Denon Germany. No one could explain why I had such massive problems. Those were **** expensive losses I had .... I'm really happy, but manufacturers, Apple and forums have declared me crazy!

Hey, yeah same here. I'm note shure how to downgrade my system. I call the Apple support tomorrow

Here's one method… https://www.imore.com/how-downgrade-macos
