was heavily involved in the beta testing of 10.10, In my experience Yosemite is by far not only the most buggy, but also slowest release of OSX. I am saddened to report that only one of the many performance regressions I reported was actually fixed (In that case within Mail.app). A huge portion of the performance problems seem to be stemming from the graphics subsystem. If you use Yosemite on dual Retina or even WQHD displays you'll know what I'm talking about. Add graphics glitches, immature theming and wireless problems to the over all poor performance and were talking about major issues in areas that OSX has been known as a leader in. My biggest issue is that Apple seems to be ignoring most of the core performance issues that are being reported - just look at the number of unresolved posts on the Apple forums. I do hope that Tim Cook is becoming aware of the drop in reputation that OSX has received since Yosemite and is leading his teams to perform more in depth performance soak testing before releases in the future.

Its especially bad on the 13" rMBP which has a relatively weak GPU. When using scaled resolutions the UI lag is very noticeable, i also get some redrawing issues of icons. You can improve the situation by disabling transparency effects, but that produces some graphical glitches. In the end i disabled retina resolution and am running native 1680x1050 now. Definitely not as crisp but i got used to it and system load is considerably less (especially when playing back video and such) now and battery life improved as well. Current GPUs in the Macbooks are just not ready to handle the massive resolutions used for scaling. Just try to run a 60fps youtube video in a scaled resolution and you will see your system load go up to the point the video might even stutter.

I don't think that 1680x1050 is native or even half-native on the 13. IIRC the Air is 1440x900 and the 13 rmbp is less than that (when you count the points). This is why I keep telling people who want a 13' Mac to get the air, but sadly very few listen…

    I used a 11" Macbook Air at uni before getting a rMBP. IT was buttery smooth, nothing could make it stutter on Mavericks. Great experience although the screen size was a tad on the small size. I eventually settled on a rMBP 13" (2014 edition) and couldn't be happier. Sure, i sometimes get stutter swiping through fullscreen apps or using Chrome on heavy pages but the retina and its scaling makes it so much worth it. Seriously, couldn't be happier. Reading text on this is phenomenal. And it's not buyer's remorse or anything like that, i got it for free through a university programme and could have got the Macbook Air if i wanted to.

I don't understand why they insist on the fixed yearly release cycle. I'm convinced that's the real source of most of these problems; Yosemite might have been awesome with a few extra months of testing and polishing, it was a major release in many respects and 12 months is very little time for projects of this magnitude. Is it just because iOS is forced to release in sync with hardware, and hence OSX has to follow suit in order to support new iOS features as fast as possible? What is the point, if the experience is then sub-par?

Sounds to me like they were pushing the feature so they can run up against hi-res machines from competitors. Anybody with one of the new 5k imacs want to chime in? Similar graphics issues.
