new_disprd failed with ‘Instrument Access Failed’

[Davide]

Hi All, I’m trying to use DisplayCal on mac OS Sonoma for an external monitor connected to a MBP.

I use usb A to usb C converter (tried different one) to connect my old Spyder4 to the mac.

I installed DisplayCal with python as the release was not working with sonoma.

Argyll version 3.1.0

When I try to calibrate I always obtain the following.

Do you have any idea? Appreciate any suggestion, thank you so much
