The monkey app was the latest version from Line6, and the driver was the latest available from the Monkey app, onto a brand spankin', unmigrated install of Yosemite (build 14A389) onto a brand spankin' iMac. Installed the driver, had crashes on powering off the POD X3, shutdown loops, any attempt to edit the Audio/MIDI setting in Apple's app. I'd get a newer, more compatible POD--Line6 has been GREAT to me--but the X3 appears to be the only one with multiple outputs. I spit one out wet and one dry into Logic for an instant overdub, printing effects to tape AND editing in software.
This has killed my project. Help.
