I have it running on multiple devices and haven't had any issues. Just a couple of small bugs here and there, which is expected from any software. Especially a project as large as an operating system. Of course my experience doesn't speak for everyone, but I have a feeling that some of these people use every little bug they come across to rail against Apple in the forums. It's like the little popping noise the 16" MacBook made when you paused YouTube videos before it was fixed in 10.15.2. Was it really worthy of a bunch of posts on how Apple's quality control is terrible? Probably not but we still got them
