Mac Mini (2018) has problems with Logic Pro X

Just got the new Mac Mini 2018 (6-core, 8gb model).

My Logic Pro X projects run very instable. Crackling audio, error messages, weird sample rate warnings. Only solution seems to be cranking the buffer size up to 1024.

The projects ran much smoother on my 2014 MPB (2,5Ghz i7).

I've tried running the audio through the internal audio device, through my UA Apollo Duo, and M-Audio 2x2M, but the problem persists. I also tried resetting PRAM.

Anyone had a similar experience or have any suggestions?

Mac mini (2018), macOS Mojave (10.14.1)

Yes! I forgot the most obvious. Some 3rd party plug ins create clicks/audio drop outs when you upgrade your OS or change part of your system but don't re-authorize your plug. They do it as a way to disable your project, but don't tell you that. (If I remember correctly, I went through similar frustrations that I once attributed to my audio interface because I thought I'd ruled everything else out, but it turns out IZOTOPE products - Ozone, Neutron, Nectar etc - can sometimes need re-authorization or you'll suffer the same problems you're going though.)

Check your plug ins to ensure they're all properly authorized and let us know.

The problem persists after updating to Mojave 10.14.2. Updating Logic to 10.4.3 and updating UA-drivers to 9.71 (problem persists regardless of which audio interface I use. Also persists with internal speakers.

Nice to hear.

Maybe it's an issue with 3rd-party plugins?

I'm mainly using a combination of the built-in plugs, Waves, Soundtoys, Arturia, EZX and a few UA (though the problem also persists in projects with no UA-plugs..). All plugins are latest version.

This is really small bug btw maybe because my two aggregate sound cards configuration.... I notice this once a day or two now. Mini works preatty fast. Also UAD plugins work fine on Mojave ( officialy not supported ). So happy by now ;)

Creal7, so it’s not happening on a MacBook? This would point to the mini itself, or maybe some combination with Mojave. (I have no idea what I’m talking about. And frankly, I shouldn’t have to. I have music to make.). I suppose that could be fixed with software as well, if they investigate. Or even care at this point - they have to get their telephone business in order.

I'm at my wits end with this issue. It is unbelievable that Apple would release OS software with these issues. I am essentially stuck until there is a fix. We buy the latest hardware and trust that it will all work - and this has been a complete failure. Please if any one finds a solution post it here!

What I don't get is the multithreading options:

The Logic article says this...

• It's not possible to split a single thread across multiple cores, although a single core may run multiple threads at the same time.

If that's the case, then why is there an option for setting multithreading for live tracks...

Multithreading pop-up menu: Determines whether multithreading is set for playback tracks only, or for playback and live tracks.

These two seem to contradict each other unless I'm not getting what the pop-up does. If a channel has to be on a single thread, then how could it be multithreaded?

I’m thinking of buying the same 2018 Mac mini so please let me know if re-authorization of plug ins solved the crackling audio playback, or if still is an unresolved issue.

I have exactly the same issue. Did you solve it? If so, how? My Mac Mini is i5 3.0ghz 8gb. Thanks.

No I did not. I noticed crackling also on regular preview tracks so have no idea where is the problem and how to fix it. Its really small but system bug in my opinion.

Dec 21, 2018 6:50 PM in response to Matush

It’s not a small bug! I can do no recording at all until it is fixed. I can’t believe I just bought the one computer won’t work with logic.

Dec 22, 2018 7:37 AM in response to mikkelbh

I do not have the issues that you are having and I am also running UA hardware. However I will say that this mini with the i7 runs much much hotter than the iMac Pro that I had!
