ok/tks. As feared. Helix was why I had to wait so long for the last macOS update...and it seems it will be this way again. All of my other critical apps (SMAART, VMware....) are already good.
Seems odd to me that Line6 (or Yamaha or whoever is in charge) can't sort out how to stay/get current w/ these updates. As a college trained programmer, I realize there are lots of issues but so many other companies have it worked out.
Peace.
