Cannot update PBF4 firmware

I have some issues with sending MIDI to my PBF4 ever since updating my macOS version. There is a Processing sketch that sends values for the LEDs corresponding to their addresses. I can see that the messages are actually sent from the sketch via MIDI monitor, but they stopped triggering the LED changing on the controller.

I did not change anything about this setup since it was last working, except for updating my macOS version from Sequioa to Tahoe. I did not change the code, did not update the firmware or Grid Editor, did not even open the Grid Editor since loading my configs on it last.

I went to investigate in the Grid Editor, which wasn’t readable anymore on this macOS version due to severe UI issues (black on grey text?). I figured to update to the latest (now grid-editor), which of course also prompted me to update the PBF4’s firmware. But if I hold the utility button while plugging in, it does not seem to start the bootloader mode. The grid-editor does not prompt an update and the controller’s LEDs just go to a constant green.

Resetting the controller manually via pressing the utility button shortly after plugging the cable in does not reset it either, it just prompts a page change (as that button normally does?).

What do I do? I have a show on monday and was expecting as long as I do not change anything a simple MIDI receive should work even when I update my OS. I can not update or reset my firmware either? The thing is that the setup still works as in it sends the correct MIDI messages to my Processing application, but if updating the LEDs does not work then I can not really use it.
