I found this:
Currently, Native Instruments software and hardware products are not supported on macOS 14 Sonoma. We cannot recommend to update to macOS 14 at this point.
Well, I just spent 6-8 hours trying to install some Komplete libraries. I searched the web several times with Sonoma + Native Instruments, but initially found nothing.
If NI had mailed us all with this statement, I would not have wasted time on a hopeless task.
