For the past few years I have avoided upgrading to High Sierra on my iMac because Logic Pro X ran so reliably on it. Recently I decided to take the plunge an upgraded to Sierra (I was still using Yosemite) and NOTHING, I repeat NOTHING works. Can't even pass an audio signal, even though my interface registers it. All my effects sends are X'd out. Same with VIs. Cannot even play existing tracks. I anticipated some issues with an OS update but this is rediculous! Can anyone help? Thanks ahead of time.
