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!

Re: Concurrently running RME USB kernel extension detected

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

Thanks - to be on the safe side I have now gone through the procedure, got rid of the kernel extension and successfully reinstalled the other software!

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.

How does Rogue Amoeba do it?

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

thanks

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. MADI channels, is the unit connected to USB 3?

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
