Topic: Reboot - New macOS RME Thunderbolt driver – public beta test
This is a reworked macOS Thunderbolt DriverKit driver for macOS 12 and up.
Attention: The UFX+ requires a firmware update to version 110 (AKM) or 164 (ESS) to enable the use of this DriverKit driver. Link to firmware update tool:
Current driver version: 1.01. Included TotalMix FX: 1.78. This is a special DriverKit version that is not compatible to previous drivers.
System requirements: macOS 12 and up, Intel or M processor (Apple Silicon)
Installation: Double-click on driver_mac_tbdk_101.zip to expand the archive file to the driver file UFX+ Thunderbolt DK.pkg. Installation works automatically by a double-click on the pkg (package) file. Before reboot check that in Security & Privacy, tab General, the RME driver is allowed to load. If not unlock the settings and allow it. Then reboot computer.
A previously installed kernel extension driver, like 1.21, does not need to be uninstalled. It will be overwritten automatically. After that you could set the system security back to normal, unless any other existing kernel extensions still need reduced security.
To go back to 1.21: easiest method is to drag the RME Thunderbolt Settings app found in the folder Applications to the trash can - only use the Finder for this action. With DriverKit this Settings dialog is 'the app', upon removal all driver files belonging to it will also be removed automatically. You will be asked for permission for the removal of the extensions. If done simply reinstall the former 1.21.
As an alternative we also made a version of the 1.21 driver available that should reliably remove the DriverKit extension during its installation, see link below. The one found on our website for download is not guaranteed to always do that.

Any feedback is much appreciated.
