Sorry to hear that. When was it discontinued? 4-5 years ago. And now not technically supported any more? It doesn't make me to wan't a new one.
Older drivers? There was other issues (Kernel panic) with Yosemite an the Pod X3 that older drivers couldn't manage, so, no...
Line 6 knows about the issue...
And now...looking for other solutions...unsubscribe Line 6 newsletter...delete Line 6 bookmark...going to check out Guitar Rig...oh no, I'm not bitter...;) but it's time to part ways....
I promise...this is my last post on the subject...
Thanks for your reply...
