Using MR12 interface with 2016 MacBook running OS 12.7.6. Interface works with Garage Band, but updater gives error message stating “UR not found. Restart this device and try again.” I already installed the Yamaha USB driver because it asked me to do that first. Now I cannot get it to detect the UR12 when trying to do firmware updater. Any help appreciated greatly!
DISREGARD! My issue was that the Yamaha USB driver was being blocked by security protocols. Once I approved that, it informed me that the most up to date firmware has already been installed. Blessings!
