Topic: Concurrently running RME USB kernel extension detected

I've just updated the driver from v3.28 to the latest version (v4.07) on my macOS 12.6.3 Apple Silicon machine and am now getting a pop-up dialog with the following error message every time I connect my Babyface Pro FS:

https://i.ibb.co/bWQDk5V/Screenshot-2023-03-20-at-23-12-22.png

"Concurrently running RME USB kernel extension detected! Please try to reboot your computer.
If this message persists, disable third party kernel extensions in security policy!"

Needless to say, I've rebooted the machine more than once and that does not solve the problem.

How do I solve this?

My firmware is also on the latest version, 203.

Re: Concurrently running RME USB kernel extension detected

As it says - turn back the security settings that you changed for installing the 328 drivers. See its readme if you forgot how to.

Re: Concurrently running RME USB kernel extension detected

Thanks, that worked, but a question:

What's the name of the v3.28 kernel extension so that I can delete it from my system rather just block it?

Re: Concurrently running RME USB kernel extension detected

You won't find it - that is the issue our new installer works around as good as possible plus gives this extra information. Set System Security back to default is the safest way to get rid of the old kernel extension being loaded in the background.

Re: Concurrently running RME USB kernel extension detected

Hello MC. I did that. However, I'll have to re-enable the reduced security because of Rogue Amoeba's Loopback ACE component. How do I prevent the concurrent extension problem in this case?

Re: Concurrently running RME USB kernel extension detected

I apologize up front for a newbie question, but I installed the 407 drivers over the 3.28a and am getting the same pop-up.  I've read through the Read Me for the 3.28, 3.28a, and 4.07 and after looking several times through System Settings and cannot find how to turn off the extensions.  I also did several Google searches.  I also just yesterday updated to the new Ventura 13.3.1 OS which might impact this. If I could kindly ask for some steps maybe more detailed than what I find in the Read Me, I would deeply appreciate some help to get rid of this pop up.  Thank you in advance for the help!

Re: Concurrently running RME USB kernel extension detected

Getting rid of the old kernel Extension is not complicated, but cumbersome. We assume that the sticky KE is a bug on the later Ventura versions. Anyway, here is the procedure to get rid of it:

- Boot into Recovery Mode and set the security settings back to Default (High).

- Boot into the normal macOS.

- Reboot again - the hint is now gone because the OS has removed the (all) Kernel Extension.

If it is necessary to reduce security again because of other software (e.g. Rogue Amoeba), you can do that now.

After that Rogue Amoeba (example) has to be reinstalled, because it was also removed by the process of increasing the security and rebooting into normal macOS.

Re: Concurrently running RME USB kernel extension detected

Kind of annoying that you guys don't put some sort of warning about this.

Im not really a Mac wiz by any stretch 

Is this not going to affect any other apps that have enabled kernel extensions with, such as Idrive?

Re: Concurrently running RME USB kernel extension detected

If they needed to set security to low - yes, as clearly stated above. Otherwise no. Not sure why you ask this at all. You must know what you did when you connected the Idrive.

Re: Concurrently running RME USB kernel extension detected

Hi Matthias!

Similar scenario here - M1 Mac Studio (macOS 13.4) + Babyface Pro (203), I went to v4.08 drivers from v3.28.
I only get this message pointing to an existing RME USB kernel extension when starting "Fireface USB Settings".
Besides that message anything seems to be working properly.

So my question is:
Would there be any drawbacks or stability issues if I did not "uninstall" the RME kernel extension?
Since I also need some kernel extensions because of third-party software, I would like to avoid reinstalling the associated software after I have previously turned off the extensions and turned them back on again. 

Thanks for your support!

There had been posts here that removing the Kernel Extension also removed issues with audio when using the DK driver...

Re: Concurrently running RME USB kernel extension detected

I agree 100%.

There should be an uninstaller for this.

Re: Concurrently running RME USB kernel extension detected

The uninstaller is part of the driver installation and not working correctly due to some wrong behaviour of the latest macOS.

Hi I can't find this either, how did you get rid of the popup? I can't find anything in Security settings

Re: Concurrently running RME USB kernel extension detected

I am also unable to fix this using any of the methods provided here.
I can't change back the security settings because my Universal Audio products also need them.
Did anyone here manage to do a proper uninstall of RME drivers and software and get rid of this "concurrently running issue"?

Also my Fireface UFX III is not showing all the software playback channels (MADI 1-64 are missing) in Totalmix even though they are available in the channel layout settings and are not hidden. Perhaps this issue is related to the double kernel extention thing?

Re: Concurrently running RME USB kernel extension detected

Hi, it looks like for the latest upgrade of Ventura 13.4.1 this problem do not exist anymore.
My configuration is: Mac MINI M1 2020, Ventura 13.4.1 and Babyface Pro FS.
I installed today  DriverKit  v. 4.08 (2) over kernel extension Driver v.3.28B and the proces went smoothly. The only thing I had to do after reboot was to allow the Fireface USB Settings app in the Privacy&Security tab.
Reading previous posts I was worrying I will need to delete the kernel extension manually from Library/Extensions and clear the Staging cache using Terminal command, but not. Before running the Drivet kit installer I opened Library/Extension folder and Staging folder to observe the presence of RME kernel extension files. I saw, that after installation finished, the driver kernel extension vanished from both, Library/Etensions folder and  Staging extension Folder smile. So either Apple solved the problem with Ventura 13.4.1 or the latest installer is more effective at removing kernel extension...

So I didn't experienced "Concurrently running RME USB kernel extension detected" pop-up  after installation and reboot the OS after DriverKit installation over Kernel Extension Driver.  I hope that the installation will work in the same simple way for others smile

Re: Concurrently running RME USB kernel extension detected

Colour me "stumped." Last week, I updated my UFX+ RME FW/Drivers on my M1 MacBook Pro running Ventura 13.6 from 3.28 to 4.08... as is the case with others, I now get the dreaded "concurrently running kernels" warning.

I have spent over 12 hours reading, researching, and trying the various quasi-documented techniques in this thread and have STILL not solved the problem. Note that merely disabling all 3rd-party kernels is not acceptable, since I have other devices installed that require this functionality. It's only the RME that's screwing up.

Alas, I'm a musician not a computer programmer... which, unfortunately, now seems to be a pre-requisite to solving this issue. This is the first time in 15+ years of RME ownership that I've had an RME issue I couldn't easily rectify. Is it simply a matter that this will "go away" once I eventually update to Sonoma? Or will there be some kind of "remove the old kernel" app that RME might release to allow actual musicians to get their UFX+'s running smoothly?

Re: Concurrently running RME USB kernel extension detected

egor,

from 3.28 to 4.08

that means you switched from your old kext driver to the (newer) driverkit driver architecture.

As you didn't write more details, i can only guess:

Note that merely disabling all 3rd-party kernels is not acceptable

You do not have to disable your 3rd party kexts in general.

I think, it's just your old (3.28) RME kext driver which is still loaded...? So you have to throw away/delete/uninstall just your "old" RME kext driver. 

Did you check that your /Library/Extensions/ and /Library/StagedExtensions/Library/Extensions/ folders do NOT contain any RME related files?

Yes. all my other kext files show up in these folders, but there is nothing RME related in them. And yes, I updated from 3.28 to 4.08 carefully following all update instructions. But, as mentioned, every time I boot the Mac, I get the "concurrently running RME USB kernel extension" dialog box.

Re: Concurrently running RME USB kernel extension detected

I'm up to 14+ hours trying to figure this out now. One thing I don't understand is why, when I go into the Mac's System Report and look at all the extensions, I don't see a single RME extension? Or at least not one with the letters "RME" in the name? And yet EVERY SINGLE TIME I boot the Mac, I get the "concurrently running extension" dialog. Where is it 'running' from if it doesn't show up in the extensions list? How can I disable something that doesn't even seem to be there? Does the 'offending' kernel extension have a weird name that doesn't include the letters "RME?"? Or at least 'weird' to a non-programmer like me?

And I agree with bbjmm. In the absence of an installer that works properly by removing redundant or outdated code, it would be great to have step-by-step instructions of how to do so. Not instructions that just say "toggle the twizzler," but actually show step-by-step how to do this, and don't assume you're a Mac coder or love to spend your spare time researching the inner workings of the Mac OS. :-p

Re: Concurrently running RME USB kernel extension detected

You can try this

Clear staged KEXTs with command: sudo kmutil clear-staging
Shutdown
Boot into Recovery Options (On M1, hold down power button while booting)
Launch Terminal
Reset the KEXT system with command: kmutil trigger-panic-medic --volume-root /Volumes/Macintosh\ HD/  (Or whatever your startup is called)
Restart

Re: Concurrently running RME USB kernel extension detected

egor, bbjmm,

a lot of people are trying to help you.

Backup your 3rd party kexts to any location (and maybe also the launch scripts in /Library/LaunchAgents and/or /Library/LaunchDaemons

boot into recovery mode, disable 3rd party extensions (via full enable SIP)... yes, momentary also your other "necessary" kexts will probably not work. anyhow -> reboot -> reinstall the driverkit driver -> reboot again...

Works now?

Than you can boot into recovery mode again and disable your SIP. And your neccesary 3rd party kexts should work again.
Maybe you have to copy/reinstall the kexts to its old locations from your backup. And reboot again.

It would help more to get a detailed feedback what you exactly did and what was the result.
Instead of beeing frustrated, while it seems you have a customized environment/system.
To be clear: you are saying, you are not a tech guy - but you disabled SIP to run your 3rd party kexts...?!?
Maybe, you want to ask Apple if there is a genereal Step by Step guide/pocedure to switch from certain kext drivers to driverkit, while keeping other kexts? Would be nice if you could share it here then.

Eureka! Thank you SO MUCH mrkahuna! This was exactly the sort of 'dumb(ish) guy' guide that I needed to get through this. Obviously, once I did this I had to re-allow the two remaining kexts for other legacy devices. One of them (an old Pegasus drive bay tower) required that I actually re-download/install the drivers in order to get its disks mounted again... but this was all to be expected.

The UFX+ is now happily humming along without that annoying "concurrently running kext" dialog, and my other kexts are functioning properly (at least until I update to Sonoma -- but those are problems for a whole other forum :-p )

Many thanks! And a heap of virtual internet gold stars (for whatever they're worth).

I'm also getting the KMErrorDomain error, but the installer says "success", and I'm not getting the "Concurrently running" error.

Seems like everything's fine for me despite the KMErrorDomain error.

Same issue:

Error Domain=KMErrorDomain Code=31 "Error occurred while building a collection:
Cannot build collection without binaries as only 1 codeless kexts provided" User Info={NSLocalizedDescription=Error occurred while building a collection: Cannot build collection without binaries as only 1 codeless kexts provided} (base) …

I have not set back the security settings as the pop-up window suggests after a mac reboot, but I guess the pop-up window should not appear if the uninstaller worked properly.

RME, how can we properly delete the kernel extension driver and not just blocking it?

Re: Concurrently running RME USB kernel extension detected

That error message is not an issue. Neither is the Security Settings warning. Only if the RME driver itself warns about the Kernel Extension. As that did not happen everything seems to have worked. See post #35.

hi - after trying to resolve the "concurrently running kernal issue" i find myself in a strange situation ive not seen described so far ( let the finger pointing begin).

system - Macair / m1 / osx 13.6.6 - was working with Rogue/ACE components installed for years. the occasional 'RME-concurrent' msg popping up which i stupidly decided to resolve last night.

after reboots, and changing security settings as described here and linked posts, i have sound from my system/finder/daw running thru my digiface ok.

    However no sound will play thru brave browser when usinig the RME card.

      Sound does work from brave to the internal sound cards.

        Rogue Amoeba/ACE has been fully removed, and system tested with and without it installed, same issue.

          Brave and totalmix, and all files reinstalled, all preferences and config files deleted multiple times to a fresh install, yet the same issue remains.

            Chrome browser + RME does work

            So this is specific to the Brave and RME combination..

            any advice please on how this might be resolved.

            thanks in advance

            edit- ive also contacted rogue amoeba asking for assistance.. perhaps this is related to ACE, though i did remove this carefully also.

            yup... reverting to an older version of brave resolves this. Unfortunate timing i guess that the auto-update occurred at the same time as fixing the RME issue..

            i will delete my initial post to keep this thread on topic.

            edit - this is fixed the the latest nightly build of brave (Chromium 124.0.6367.82) - interfaces with over 32 outputs where not supported correctly , now fixed.

            Re: Concurrently running RME USB kernel extension detected

            Edit: I just read above and as long as installer is successful then it's a false alarm. Could do without the message, but RME has always been so good about keeping gear alive a long time and updated so won't complain.

            I just updated the Babyface driver to 412 on Mac Sonoma. During the install process Terminal opened and I entered the password and I'm getting the "Concurrently running" pop-up error.

            Terminal showed:

            dj@DJs-MacBook-Pro ~ % sudo /usr/bin/kmutil rebuild
            Password:
            Checking the auxiliary kernel collection...
            Error Domain=KMErrorDomain Code=31 "Error occurred while building a collection: Cannot build collection without binaries as only 1 codeless kexts provided" UserInfo={NSLocalizedDescription=Error occurred while building a collection: Cannot build collection without binaries as only 1 codeless kexts provided}
            djm@DJs-MacBook-Pro ~ %

            Rebooted a couple times and still get the same "Concurrently running" error. Any ideas what to do next with the above info? Thanks!

            Re: Concurrently running RME USB kernel extension detected

            1) do you have the "Concurrently running RME USB kernel extension detected" popup as you posted on other other thread?
            2) Seems not, as you tell you installed drivers?
            3) Which driver exactly did you install?
            4) Which UCX excacly?
            5) Firmware updated?
            6) M1 or intel mac?
            7) "Start and Stop problems and various" -> what do you mean exactly? can you post screenshots/videos?

            Please answer the questions, so it would be possible to understand what your problem is...

            Re: Concurrently running RME USB kernel extension detected

            I had to upgrade from Sonoma to Sequoia to get assistance from Apple for a malfunctioning keyboard. After that upgrade I Now got this concurrent kernel problem with my RME 802. I think I have ticked every box under settings but this keeps popping up. Ideas?

            There is nothing to tick. You need to install the DriverKit driver and type in your password correctly, that will remove the KE one. Or stay with the Kernel Extension driver. See driver readme for details.

            Ahh. Never used that script window before. If was not clear to me that I could type a password in there. Now it seems to work after another install.
