With good reason, too. A good portion of the Native Instrument software packages won't install because the installers themselves rely on 32-bit helpers. A savvy technical user can work around it by unpacking and excising the problematic portions from the installer scripts.

On the plus side, I've been running Kontakt 5 along with lots of other audio software since 10.15 beta 3 every day and most everything is working alright.

Some other observations:

• Pro Tools' QuickTime video plug-in prevents it from launching because it's a 32-bit only subprocess meant to interact with the now-defunct QuickTime framework. You can delete the plug-in from the application bundle and it will proceed and seems to be working normally.

• EastWest has a nasty crash in PLAY 6 that can be worked around temporarily by removing their internal word builder plug-in.

• Pretty much every iZotope plug-in as of September had a 32-bit non-pkg installer. The software works fine if you copy all the relevant parts from an install on another computer.

• MOTU hardware drivers for anything but the latest Pro Audio line won't work as the drivers are 32-bit at the moment (MIDI interfaces, CueMix-based audio interfaces).
