Hi shaguzulu,
I’m on a 2017 iMac Pro with Mojave, using a number of hubs between the Mac and the PD. Even in this scenario - the CMC-PDEditor launches and runs fine, as far as I can tell… it certainly sees the device. By the way - I agree that the PD pad controller is one of the best midi input devices I have, and sees constant use!
Write back If there’s any system config or other info I can provide to help.
