Topic: UFX+ Can’t Connect Via TB to M1 Mac

I’ve been able to successfully connect my unit via USB, however I want to connect it via thunderbolt 2. I’m currently using an authorized thunderbolt 2 cable via an Apple thunderbolt 2 to the thunderbolt 3 adapter that are going directly into the computer itself. I’m doing this on an M1 pro MacBook Pro on the latest version of Monterey.


I’ve gone to RME’s website and looked at how to install the driver on M1 certified machines.

I followed those instructions, download the driver and installed it. I still get nothing. The RMA totalmix app does not see it, nor does audio midi setup within OSX.

What am I doing wrong

In the UFX + settings (options> interface Mode) you may select to switch automatically. Or you select manually. If the white LED is on, Thunderbolt is recognized and selected.

I’m having the same problem. Works fine with USB but not with Thunderbolt. It will not even load up with Thunderbolt. I have tried switching it to TB manually on the unit itself and that did not work either. Is it a driver issue?  I am using the most current public release.

I think the issue is the Thunderbolt driver cannot be installed.  It gets blocked by Apple.  When I try to open up MacOS settings to allow it, the allow button is not there.  RME has said if this happens, to install the driver again.  I have installed the driver several times and the allow button is still not there.  And yes, I am booted up with limited security as stated by RME and still no allow button.

Re: UFX+ Can’t Connect Via TB to M1 Mac

Resurrecting this old thread because I was dealing with the same issue, and have a resolution. In Sonoma (14.6), once Kernel extensions have been allowed through the recovery mode Startup Security Utility, restart the machine and navigate to the system settings. In the Privacy and Security tab, under the "Security" header, there should be an option there to finish the authorization if you have already attempted the install. Otherwise, it should operate as described in the installation overview.
