Nothing has changed on my Mac Mini and Mac OS 10.14.3.

That sounds terrible, I have a concert next week and i'm afraid to use the 2018 13" with FireFace (because of the 13", not the fireface), it's giving me anxiety

edit:
on the mini, even if I load all cores max with yes - dev/null and playback audio in logic at 128samples/buffer, it seems to play without glitches. Jesus this is giving me so much anxiety

Yeah, thanks! By the way, i had been working for two days with 802 direct to a mac mini 2018 (direct USB, no hub) with 10.14.3 and Pro Tools and i can´t hear dropouts. Seems to be ok and stable for me...maybe is only matter of time hear the errors, or the usb problem is solved or not all the systems have it? anyone running 802 ok direct to usb?

I am also still getting the odd dropout and click whislt rendering with the caldigit and digiface usb, will this also be resolved with new driver?

My post got lost there.

Also am still on 14.2 is 14.3 worth it for now?

installed.

Regular clicks and pops, at 64 buffer size, but CPU at 10% max while monitoring.

I have a high channel count > 32 channels in and out..

I confirm that sound plays now when UCX sample rate is set to 192kHz and connected to the CalDigit hub.

Re-install the former driver to verify. We are not aware of changes that would make driver 3.15 generate louder 'pops and bangs'. BTW, if you are not even sure if 64 really worked correctly before, what are we discussing here? You need to set 128 anyway for reliable, real-world operation on your Mac.

Hi, there is any alternative (tested) to caldigit th3? i´m sure mine is defective couse disconnects all connected peripherals by lightly touching the rear cable of the hub, and now it's no longer available on amazon EU.  Thanks. On the other hand, the new driver  works perfect at 88.2.

Currently on a session recording 21 channels into Reaper on a 10.14.3 2018 MBP through a MADIface Pro via Caldigit at 44.1k.

Very frustrating to catch a glitch on a good take this morning despite a sample size of 1024 and CPU load of <6%

Currently on 3.14 but I’m too nervous to upgrade to 3.15 mid session as this crashed our Mac Pro on Monday which wouldn’t restart. However, would the new driver likely solve the glitches?

Current version is here:

Not sure how a simple driver install can prevent your Mac from booting, but it might help to disconnect the audio interface after running the driver installer and  before re-booting, and connect again after mac OS is up.

No, that sounds like other issues. Check the logs to see what error messages you get. Most probably something like this:

standard    18:01:05.027413 +0100    GigPerformer3    HALC_ProxyIOContext.cpp:1068:IOWorkLoop:  HALC_ProxyIOContext::IOWorkLoop: skipping cycle due to overload

standard    18:01:05.035574 +0100    coreaudiod    HALS_OverloadMessage.cpp:165:perform:  Audio IO Overload inputs: 'de_RME_driver_USBAudioEngine:45

Or similar. Maybe you run into thermic problems as reported by many websites with that model? Also graphics affecting audio is a very different topic and points to either the hardware architecture as such or the current graphics drivers.

Will check logs, but do I need to hear an error then find the log?

No thermal throttling here, only heard the fans once on a hefty render.

Hi,

May I ask if this does affect only USB interfaces or Firewire as well?
Basically is it possible to use a Mac with t2 chip (like 2018 Mac mini) with a Fireface 800 or do you get audio glitches there as well?

Thank you!

Just wanted to offer some feedback that I had to send the Caldigit back. The intermittent dropouts with a direct USB2 connection did stop with the Caldigit, but then I had a couple of other issues: 1) When the computer woke from sleep, USB was not working until I unplugged and replugged the Caldigit. 2) Very rarely, audio would stop completely, even though Ableton kept on going...meaning the computer thought the interface was connected, but no audio came out of the interface.

I suspect both of these issues are related to the fact that the Caldigit is bus-powered. I am investigating powered thunderbolt 3 hubs to see if that solves the problem. Here's a Cable Matters hub that's not as expensive as the bigger hubs, and I'm hoping that powered connection will eliminate the last of these nagging issues: https://www.amazon.com/gp/product/B01DYFHYNS - I will report back.

If anyone else can share other hubs that have worked, that would be great. Thanks.

PS - it still blows my mind that Apple hasn't owned or resolved this issue. There is no USB2 interface (which accounts for most interfaces in audio these days) that will work with the 2016-onward Macbook Pros. WOW.

In regards to my last post I am seeing dropouts in Console.  After recording a stereo track for maybe 15-20 minutes in Logic Pro 10.4.4 it glitches and stops recording completely which renders it useless.  That’s really sad to spend $1099 on a computer and $1199 on an interface for it not to work and have these kinds issues.  To have to spend another $150 for a TB3 hub kind of makes me sick to my stomach after switching over from the Linux audio ecosystem which doesn’t compare to what Apple offers to pros.  This doesn’t happen on self built hackintosh Mojave so I know it’s the Mini.

The interface is awesome!!!  I started using Linux because of headaches I had with Windows after 10 years of use.  Won't go back to that again.  I actually really love the Mac mini except it has this issue with the USB2 controller.  I'm literally on the phone with them now producing a ticket with error logs provided to them per their request.  So fingers crossed.

I am sad to report that the Cable Matters hub is unusable. When you plug in your USB2.0 device, you will hear a high pitched electronic noise - just put your ears to your monitors and it's there. This is the same noise I used to hear back in the PC laptop days when you had grounding issues.

This is getting so frustrating. I will now try yet another Hub. Sigh.

Good to hear a candid response from Apple.

However, according to your advisor USB 2 over USB-C should also work but it doesn’t, only USB 3.

Also USB-A on previous Macs was working fine for 10+ years so why did they change it?

What are you so happy about? What did you get from Apple apart from a statement which is technically wrong and with which Apple simply tries to get the matter out of the world freely according to the motto "rather an end with horror than a horror without end". At the end of the day, it's just internal damage control at Apple, but the customer gets nothing at all.

A clever move, because many Apple owners are still very much behind Apple and apparently believe such statements.

But you could also use such a factually wrong statement to simply return the defective device and have the money refunded, be it by way of goodwill or legal action, or perhaps to get a device on which you don't have the problems on the hardware side, at least.

But you need also to take care to get HW that runs perfectly on "High Sierra", because in "Mojave" there are still bugs in the USB stack and OS services, that prevent uninterrupted audio.

I'd expect some solutions from Apple, they've been doing this for more than half a year now and are still claiming that it's due to 3rd party devices/drivers, although it's already proven that the problems also happen with their own drivers and DAW program (i.e. Logic) when running devices in Class Compliant mode, i.e. without RME drivers. And it is not only RME customers who have these problems, the list of companies is already considerably long.

Dude ? Relax ? How about just sticking to the facts without becoming personal in any way ?

Sorry, but what you're saying isn't right. Apple Support has told customers in all seriousness that these are problems with 3rd party devices. And this although Apple's own drivers also fail when connecting devices in Class Compliant mode.
Apple's comments that the USB interfaces on the new Macs are not intended for audio are also pure stalling tactics. These are absolute smoke bombs to appease customers who don't know better.
All I've said is that I see no reason to relax. Apple rejects everything. Both in terms of hardware and USB stack / Mojave. Nothing has changed for more than half a year.
I'll be curious to see what happens next. At the moment the customers are dependent on the previous operating system version, because Mojave is simply unusable for audio processing.
And in terms of HW .. the only solutions are at customers cost (Thunderbolt HW bays).

Pc vs mac thing is so fundamentally retarded lets not go to that. In my opinion it's really interesting and good to get a confirmation from apple representative that they know about the problem, usb only for charging explanation is really stupid though, one can only guess if that's what is being taught to customer service for now is really to buy time to find a workaround or does it mean that they never will be able to fix the issue with current hw.

Anyway Ramses, is it really for sure that mojave won't work in pre 2018 macs properly? On my 2018 mbp i had high sierra first, then mojave and to me there was no difference in audio performance. With usb both os's glitch like crazy. Tb3-fw was the first workaround and it worked really well (only used it on high sierra though), now i have caldigit mini dock on mojave and is running great so far, i havent played gigs yet, only studio work but so far flawless on 4-5 sessions.

There was just a mojave update, i wonder if that helped anything audio related.

That's about the worst lie I have heard from a senior advisor. Think about it. How in heaven's name can a USB port be designed only for charging devices?

Apple seems to think all their customers must be idiots.

The real reason is the T2 to USB bridge chip. That's an Apple hardware design and it doesn't seem to conform to the USB specs. It also seems an odd choice to let the T2 communicate with the outside world via USB. PCI seems a much more appropriate choice.

Anyhow, thanks for reporting back. Now the Mini is also off my buying list. Sad, being an Apple user since 1989, all that is left is the second hand market. Anything made after 2014 seems to be a pita.

Linux seems more and more attractive by the minute...

USB can only work if hardware and drivers are based on the specification.
Ok there are certain chipsets known that do not work well, see handbook in terms of ASMedia, ..
But this is another thing it doesn't mean that there can only be ports there for charging but not for devices, in particular Audio devices.
Even more ridiculous .. USB is designed as multi-purpose interface so that you can connect different devices: phones, Microphones, Harddisks, Audio Interfaces, Bluetooth Adaper, etc etc ...

So ... it's complete nonsense what Apple says. If a device has a USB2 or USB3 port, then the interface-specific properties (different transfer modes, speeds) must also be adhered to. There are no USB ports that are only for charging. There are also no USB ports for audio. Recording interfaces use certain transfer modes, which the standard USB interface has to bring with it. Probably this should not even be called USB2 or USB3.

But you would have to google yourself for more details, I don't have the time.
There are lawyers that are specialized on computer stuff btw ...

Not sure what your personal aim here is .. maybe you 1st talk with your dealer whats possible.
Maybe you can return or replace with an older working device, etc ...
It's most likely anyway not worth the time to go to court, as this might take much time, potentially also money and this might be different in every country, as every country has different laws.
