Topic: UCX DriverKit / Kext on Sequoia 15.1 - No Go

Hi,

I'm struggling getting my Fireface UCX to run on Sequoia Developer Beta. I have tried both the Kernel Extension driver and the DriverKit ditto.

macOS always boots with a "System Extension failed.." dialog.

The UCX is connected via USB, and has the latest firmware (49). It works fine on the same computer under Monterey, or under Windows.

Any hints on what could be wrong would be very much appreciated.

I use 4.16 driver for Digiface USB on Sequoia 15.0 non-beta, it works fine.
You may test with the official Sequoia release.

macOS always boots with a "System Extension failed.." dialog.

Its probably, because you did not allow the DK to startup in the Security Settings.

Edit: See:

Both (DK and kext) Drivers work here without problems, too (current Sequoia beta and the official 15.0).
