Topic: New macOS RME USB 4.03 driver – public beta test
HotFix for Big Sur in V 4.03: Driver is now compatible again.
This is the third update on our macOS USB DriverKit driver, see here: https://forum.rme-audio.de/viewtopic.ph … 62#p187362
Version 4.03 has these improvements:
- More interfaces supported
Attention: Fireface UFX / UCX / UC / 802 and Babyface require a firmware update to versions UFX: 361, UCX: 49, UC: 127, 802: 17 (111), Babyface: 226 to enable the use of this DriverKit driver. Link to firmware update tool:
https://www.rme-audio.de/downloads/fut_usb_mac.zip
Update: The FUT can now run on M1 without asking for Rosetta. But as it needs the driver, and the driver is not working as long as the firmware has not been updated, it is necessary to update the firmware of these interfaces using the former kernel extension driver first!
- Various small improvements
- Fixed installer. On new installations the audio plugin was not installed correctly, so the unit was present and detected, but no audio channels appeared in the system
Current driver version: 4.03. Included TotalMix FX: 1.77b1. This is a special DriverKit version that is not compatible to previous drivers.
New in TotalMix FX 1.77b1:
- Support of the additional devices
- Improved search function in the Workspace Quick Select dialog
- MADIface XT: Gain reduction meter did not work in the last channel
- DAW mode Speaker B: On changes the routing was not restored correctly
System requirements: macOS 11 and up, Intel or M processor (Apple Silicon)
Installation: Double-click on driver_mac_usbdk_403.zip to expand the archive file to the driver file Fireface USB DK 403.pkg. Installation works automatically by a double-click on the pkg (package) file. Users that tried version 4.0 will not see the Allow dialog and button anymore. All others should get that dialog, and before reboot should 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.
Notes
A previously installed kernel extension driver, like 3.27, 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 3.27: easiest method is to drag the Fireface USB 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 3.27.
As an alternative we also made a version of the 3.27 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.
