My first Mac experience was with the white macbook running 10.6. It was a really great experience. Everything was smooth and fluid like how IOS 6 was on iPhones and iPads. There were no sever frame drops when scrolling or browsing (I'm looking at you safari). Everything was like I mentioned above smooth and fluid. Then, everything went down hill with the release of 10.7, then 10.8, 10.9 and finally the worst of all 10.10. Why is it that simple animations like resizing a window or scrolling in the application folder lag ? Why isn't the same hardware lag or drop in frames when running Windows 7 (I tested this personally)? Is Apple aware of this issue? Do they not care? I thought Apple was all about the experience. Just to clarify, I went countless times to the nearby Apple store to see if the lag is present on other Macs. I tested the Mac pro, 15' and 13' Macbook Pro, 27' Imac and the Air. All lag doing the same tasks mentioned above, some less than others. By the way, this lag whatever it is a bug or an oversight by Apple is present in OS X 10.7 and above, so it is not a 10.10 issue. I hope we can have a very productive discussion away from fanboyism.
