From the Cakewalk by Bandlab link above:

Due to Apple’s new security restrictions, KOMPLETE 8, 9, and 10 HDDs and all KOMPLETE DVDs will no longer work with macOS Catalina, but your products will always be available to download via Native Access. If you’d like to install products from your DVDs or hard drives, do so before updating.

I received an email from Ableton that version 9 will no longer work with Mac latest update.
