Re: macOS Sierra and higher RME USB driver

Hey folks, not sure if this is the correct thread to share this in, but a few days ago (seems to coincide with an upgrade to macOS 10.15.6) my Fireface 400 stopped being recognized by my MacBook Pro 2019 (shows red host light, Fireface Settings will not load).

I've tried quite a few of the troubleshooting steps on the forum, no luck. However, I wanted to share that when I try to load manually from the command line like so:

cd /Library/Extensions/
sudo kextutil -v 2 FirefaceAudioDriver.kext

I get the following error:

Defaulting to kernel file '/System/Library/Kernels/kernel'
Kext rejected due to system policy: <OSKext 0x7fbe00808b20 [0x7fff84b92cc0]> { URL = "file:///Library/StagedExtensions/Library/Extensions/FirefaceAudioDriver.kext/", ID = "com.RME.driver.FirefaceAudioDriver" }

Doing a little reading, this seems to be related to a newish "notarization" step required with Apple dev tools? Hope this is helpful.

Re: macOS Sierra and higher RME USB driver

OS Mojave 10.14.6
Babyface Pro firmware v127
Driver 3.19

How can I change the bit depth in the audio midi settings?
Changing the sampling rate always sets to 32 bits. Is it possible to set 24 bits on the default system?

Re: macOS Sierra and higher RME USB driver

No, and there is no reason why you should do so. This is the interface communication bit depth. The one used in your app depends on your app and the settings that it provides.

Re: macOS Sierra and higher RME USB driver

Hi - I have an issue and I'm not sure whether it's related to the things described in this thread or not.

I'm trying to use an RME UCX with a USB connection, using the latest drivers, on a MacBook Pro using OS10.15.3. I had no problem with the security stage on installation - it came up and I "allowed" the software. The audio device is recognised by the OS and shows up in Sound Preferences. Totalmix runs, but the mixer doesn't open and in the Options menu both Mixer and Matrix are greyed out. If I choose File==> New Totalmix Window, the Device Selection window is blank. The UCX is not in CC mode.

Any suggestions?

John

Did you try to wait a few minutes? Sometimes a MIDI host blocks TM FX.

Re: macOS Sierra and higher RME USB driver

UFX update from 3.3 to 3.9...  same issues like mentioned before here. Totalmix and Fireface settings unresponsive. I've tried going back to earlier driver versions without solving the problem. I fixed it after reading about the Class Compliant Mode option and how to activate it and DEACTIVATE IT. Hope this helps anyone.

P.S. I'm attaching a picture of a portion of the RME manual explaining the process described before.

Did you direct me to the right forum? This doesn't appear to be a similar issue, but I checked what it said anyway: none of the listed plugins are present.

What conditions do there have to be for the Mixer and Matrix options to be greyed out? Does it mean that Totalmix doesn't recognise that the UCX is connected?

It does sound like that...  but it isn't the problem. I've checked this twice and even attempted to connect with CC reading "on" and CC reading "off" just in case - no difference in either state.

Anything else I can try?

Re: macOS Sierra and higher RME USB driver

Did you install the driver while having a valid internet connection? Apple verifies the driver's notarization that way. I just had that yesterday - zero error messages, the driver simply wasn't loaded. I had to get the computer online and install the driver again - the interface came back immediately already during the driver installation.

Yup, the computer was online and there didn't appear to be any problems getting Totalmix and the driver installed. The issue appears to be that the computers I've tried don't see the UCX as attached when using USB - when using Firewire, there's no problem at all.

The correct app is called Fireface USB settings.app. You have probably not installed the USB drivers yet.

Of course I've installed the right drivers! It was the first thing I did.

I never got this to work, but in the end I bought more than €100 worth of adapters/cables so that I can convert the Firewire output of the UCX to USB-C:that works fine. Can I suggest that RME manufactures a suitable adapter? It's obviously needed, as there are a lot of RME devices out there that use Firewire, but very few newer computers still have it (and Apple has gone down this ridiculous line of all USB-C). In order to use a UCX on a modern Mac, you need Firewire 400 to 800, Firewire 800 to Thunderbolt and Thunderbolt to USB-C adapters, a truly ridiculous situation, and one that I'd be very very reluctant to use in a critical situation like a stage performance.

Re: macOS Sierra and higher RME USB driver

The UCX also supports USB, right? Wouldn't that be an easier and cheaper route to your Mac? I use the supplied USB-B to USB-A cable and a $1 USB-A to USB-C adapter with my Babyface Pro on my MacBook Pro myself.

For extra clarity: there is actually no Thunderbolt to USB-C adapter, but only Thunderbolt 2 to Thunderbolt 3. Thunderbolt 3 happens to also use the USB-C connector, but it actually won't work on a plain USB-C port.

Thanks for the comments! But if you look further up this thread, you'll see that the problem is that the USB connection doesn't work for some people (including myself), and that this is a common problem with no apparent fix. I've resorted to using firewire with lots of adapters as the only way to get my UCX to connect to a MacBook Pro that only has USB-C/Thunderbolt 3 ports.

Re: macOS Sierra and higher RME USB driver

I have a Fireface UC and just updated to MacOS Catalina 10.15.7 and installed Fireface Driver 3.19.  I was able to install the Driver but it is not opening the RME program or recognizing the Fireface UC.  I followed the steps about system Preferences / Security / Open Anyway button... When I try to do that with the RME Flash Update I hit Open Anyways and another pop up window comes up to say it is outdated.

170

Re: macOS Sierra and higher RME USB driver

1. Your Fireface UC is set to PC = Windows. Change it to AP = Apple.

2. You used the latest update (_4) from the web or downloaded 3.19 earlier? If earlier then install it again with the latest update or make sure to have a working internet connection during driver installation.

I got the same issue as olivercaminos (also Mac, also Fireface UC, also Catalina 10.15.7). After installing everything following both of the steps mentioned above my iMac still does not recognize the Fireface UC.

My question is: what do you mean by "latest update (_4)"? I downloaded and installed the driver 3.19 ...

Probably I am one of the unlucky "USB connection doesn't work" people, right?

Thanks in advance!

There is no "common issue" where USB will generally not work - not sure what you are referring to.

Re: macOS Sierra and higher RME USB driver

Hello. Here a long time and happy user of a Babyface. USB Driver 3.2.4 says that it is for 10.12 and up. I'm on 10.13 and the installer refuses to install.
Also, upon further examination, after retrieving and decompressing "rme_usb_install.tar" from the installer, "Fireface USB Settings.app" it is seen as not compatible by the OS. The "info.plist" file inside "Fireface USB Setings.app", "MADIfaceUSB3MIDIDriver.plugin" and "RMEFirefaceUSB.kext" also say (and I quote): <key>LSMinimumSystemVersion</key>
    <string>11.0</string>
I don't know if this has something to do with the fact that the installer refuses to install, but at least in my case driver 3.2.4 is not compatible with OSX 10.13. It would be great if you can take a look into it. I would love to enjoy TotalMix 1.70!!
Hope it helps ;·)

Re: macOS Sierra and higher RME USB driver

The installer for driver 3.24 in driver_usb_mac_324.zip (2020-11-27) also fails for me on macOS Catalina 10.15.7, but slightly differently than for babyfacemmm. On Catalina I get an error message saying "This Driver Package requires Mac OS Big Sur or higher".

The info on https://www.rme-audio.de/downloads.html says "Compatible to 10.12 and up. Supports macOS 11 Intel and M1." The included Readme Fireface USB.rtf file says "Driver for Mac OS 10.11 and up. Supports macOS 11 and up, Intel / M1 (Apple Silicon)", so the description of the download and the included readme also don't completely agree.

I guess I need to stay on driver 3.19 for now. I did successfully flash the firmware of my Babyface Pro from 126 to 127 using the 2020-09-17 flash updater.

Re: macOS Sierra and higher RME USB driver

Hi. Please point me to the appropriate thread in this forum if this one is not correct.  Thank you.

I am using macOS Catalina at the moment, on a Macbook Pro purchased in ~Sept/Oct this year.  The RME product I am using is a second-hand Fireface UFX through the USB driver downloaded from your website a ~month ago.  Though as a newbie I'm not totally utilizing all the power/capabilities of your tool (nor those of Pro Logic), everything has been working together so far as I make basic recordings.  However...

Now I'm being prompted by Apple to upgrade the macOS to Big Sur.  Technically, it is "macOS Sierra and higher".  :-)   Any advice or concerns I should be aware of before making the step?

Thanks,
Jon

Catalina to Big Sur is quite a big change, because you’re going from macOS 10.15 to 11.0. It’s fine to stay with Catalina for a while (it will receive updates from Apple for another while) and upgrade once it is more stable. If you do want to upgrade now, make sure you install the new RME USB driver 3.24 for macOS 11 after the upgrade, and it should work. It's also a good idea to check the state of Big Sur support for any other hardware and software you rely on. Big Sur is still rather new, so not really battle-tested yet.

As with any big change it’s smart to back up your machine before making the jump (Time Machine is great). Apple also offers an easy way to install a separate instance of macOS on your machine, so you could do a fresh Big Sur install separate from your existing Catalina installation and use it to test everything before you upgrade your existing Catalina install to Big Sur.

Re: macOS Sierra and higher RME USB driver

Another idea is to not just update the current system, but to install the new system on a new separate partition or disk, at least initially to try it out, and leave the old system untouched.

Re: macOS Sierra and higher RME USB driver

It is no longer necessary to deal with partitions or separate disks (although you can still use a separate disk if you want). If you follow the link in my previous post, you'll find a way to install Big Sur next to your current macOS installation on a separate APFS volume. The cool thing is that storage space is shared across APFS volumes, so there is no need to dedicate a fixed amount of disk space to a macOS installation like you needed to do in the past.

Re: macOS Sierra and higher RME USB driver

Breun, there are issues when installing Big Sur in the same container as another APFS-based OS i.e. Catalina and Mojave. Whilst these versions of macOS use APFS, there are still some fundamental differences with Big Sur. Yes, you can use your method to test Big Sur but most pundits are recommending that this is installed in its own partition....which defeats the purpose of multiple containers and is a real pain in the ass.

Re: macOS Sierra and higher RME USB driver

Of course it's good to be careful, but those threads are all from before the public release of Big Sur, so I guess these people were running beta versions. Did you also experience these issues with the final release?

Yep, all of those issues are still present with 11.0.1

Thx, Everyone.  I will stick with Catalina for now.  ;-)
