Just like the title says, some if not most of my plug-ins are causing this problem. If they just sit on the channel strip, fine, but when I open them to tweak, these error massages pop up and audio becomes jerky almost to a halt. I have used many of these plug-ins for over a year, and this is a recent issue, and seems to be getting worse. Thinking this may be a re-install logic, or re-install OS kind of thing? I'm using a early 2015 15" MacBook Pro, 16g RAM, 500g SSD. Latest versions of both the OS and Logic. Any insight greatly appreciated!
