I do not even know why I write here, because it seems so as a Line6 independent chat surface, as Line6 does not provide any support here. But I give a try.
I had no big issue with Gearbox on OSX El Capitan, but on Sierra it does not seem to work. Install process of Gearbox 3.72 goes until "Destination select" but when I chose the one and only disk I have (SSD) then it writes "Gearbox can't be installed on this disk".
So, Huston, we have a problem. Is there anybody out there?
Or shall we just leave the space shuttle and sell all Line6 equipment we have???
