Hello,
With Mac OS 10.15 Catalina Jackpilot (32 bit) will not work anymore. As a musician I use it a lot to connect Pd to Mainstage or others.
Do you know if Soundflower that seems to be working with Mojave (OS 10.14) will continue with 10.15?
Thank you for your answers.

Jack is supposed to still work under 10.15, it's just the Jackpilot
program (32 bit) that won't work anymore. You can still run jack
manually from the command line. You might also try qjackctl instead of
jackpilot too.
