Please have a look at this post: Enscape for Mac NOT working with SketchUp (Service Pack) 2023.1

Well, that's a bummer, I'm sure it's frustrating for y'all as well. Back to SU 2022! Is there an email list I can join to get these kinds of crucial updates in real-time once Enscape is made aware of issues?
