Hello,
I have a problem after downloading some libraries.
Problem:
pkg can't be installed because its digital signature is invalid.
What to do about this?
Same thing. I have ultimate 9 and problem with installing Kontakt factory library. Pkg file won't run because digital signature is invalid. I have new Mac with m4 pro processor.
You can try and re-download the files from the Account downloads to see if that changes anything .
