Yamaha USB Driver V4.0.3b or V3.1.7 don’t work for UR22 model on MAC OS SONOMA. I’m struggling for couple of days, downloaded almost all the latest versions available on the internet. and Tried installing and unstalling, Followed all the steps described, but noting is working for me. I need help on this.
