Perhaps the following might help someone - I bought a new a Mac and hooked my keyboard interface up to it. The Line 6 Gear box softwares didn't work so I decided to download the latest Line 6 Gear Box software and drivers Gear box, however isn't compatible with the Sierra operating system that my new Mac uses. After thinking about the problem, I then hooked up my old Mac, copied the old Line 6 folder that resided in Applications, on to a memory stick. I then ran my new mac and copied the Line 6 folder from my memory stick into the new Applications folder. It might seem obvious to some but it gave me a bit of a headache looking for a solution. I'm happy to say I can now use the software again And record from Audio sources. Hope it helps someone who might encounter the same problem
