I'm starting to have issues opening Illustrator files. I have CC 2018. When I try to open a file from Finder, it won't open and if I try to open it through Illustrator, I get the spinning rainbow wheel and it is unresponsive. I have a MacBook Pro. It's seems as if many people are having issues with this. I hope it gets resolved quickly. I use Illustrator regularly. It costs too much to have unresolved problems.
