Since I upgrade to Mac studio M2 and Sonoma 14.4.1 Kontakt library is not showing up in Library-Application support folder I'm using DP11.31 as my Daw - it crashed - no error message just blank screen and computer restarts
There could be a misunderstanding here. I'm not sure why you bring that Application Support folder in the picture. Were you following these steps? Kontakt Crashes If that is the case, make sure you're looking i n the user library and not the local library.
Now regarding the full Mac crash, that sounds familar, it's most probably this issue: Kontakt 7 causing Kernel panic shutoff on Mac Studio! (KT-8785)
