I haven't use it yet, but from the pictures and videos I've seen, it looks, bad in my opinion. The notification center is extremely ugly, it looks like they tried to simplify things but made it look really unappealing, imo. I was also hoping for a transparent dock, but it looks like more of the same shadowed waste of screen, instead of looking at our wallpaper full screen. A dark mode would be nice, not some half baked inverting of colors, that is ridiculous if that's the best they are going to do. I hope they change it up between now and September, because I'm sure I will be up at midnight putting my order in when they go on sale. I can't help myself.
