I wasn't a fan of Yosemite, and I don't see El Capitan as an improvement compared to Mavericks or before, but it does seem better than Yosemite to me. Almost tolerable in fact. Observations: The fonts, to me are clearer The idiotic, overly aggressive translucency seems toned down The contrast with the "glaring white everywhere" that seemed present in Yosemite is toned down. The controls now at least have slight 3D effects (but unfortunately, so do text input fields…Jonathan Ive just doesn't "get" standards, as far as I can tell!) I don't see this as an improvement compared to Mavericks and its predecessors, but I might be able to tolerate it. With Snow Leopard through Mavericks, it was visually like I was eating a fine meal. Yosemite was like eating a meal made of canned Tuna. This, at least looks like it's a hamburger. Not quite what I wanted, but at least tolerable. One caveat: Display preferences are now "dummified." You can't really configure anything with your display. Apparently Apple is targeting the IQ less than 70 crowd. If you're a photographer or you need to be able to configure your monitor for exact color profiles, say bye-bye to Mac OS X! I guess the focus of Apple is to make everything as stupid as possible.
