    who cares, nobody resizes app store more than 1 time anyway

    Yes, unfortunately it doesn’t look like Apple worked on performance improvements in 10.10.2 at all. Mission Control is still unusable and I have to reboot my system at least once a day due to slowdowns.

    The behavior is reproducible on three Macs.

    With Mavericks and earlier I rebooted my Mac once a month. These are some sad times, even Windows runs better on the Mac :(

    This is true. But only for older machines (older as in 2011). My MacBook Air 2011 13" lags when opening a stack in fan mode, resizing windows, notification centre also scrolls slow. But on newest (2014) machines I saw no lagging. Upgrade or suffer I guess...

    Yeah, App Store lags. It lags on retina machines, it lags on non-retina machines, it has lagged in Lion, Mountain Lion, Mavericks and Yosemite, and it lags on my work Mac Pro D600 with 32GB RAM and a hex-core CPU. It lags, because its a badly optimised app with awful resize performance.

    So I suggest that you rename your thread to 'App Store still lags' or whatever. Its complete nonsense to judge about the overall UI fluidity on an OS by only looking at one application with a long history of known issues. This is opinion manipulation and borderline lying.

    Hm, 10.10.2 completely fixed UI jerkiness on my 2011 21,5" iMac. Even About Mac is now smooth and Mission Control now rarely skips a frame. I have two displays and it's been a terrible jerkfest before. Smooth now.

    Not true at all. You can see a lot of threads mentioning new machines, even the iMac with Retina Display is affected. This is clearly not a hardware issue (as in lacking performance), but related to software bugs that where introduced with OS X 10.10.

    That's funny, as if the problem were with JUST the App Store....what the video shows is just a portion of how badly Yosemite runs.

    Here's an experiment if you have a retina model 2013/2014. Reboot Yosemite. Try invoking MC after opening some apps. All great, right? That's normal.

    Now use it for a few hours (5+) and see the difference. MC is laggy as hell, preview lags in PDFs, Firefox slows to a crawl, Safari lags in pages with a lot of images (e.g. flickr, devianart, tumblr, etc...). It's terrible.

    Mavericks doesn't do this. There is a tiny bit of lag if you have many apps open when invoking MC but apart from that, it's rock solid and fluid. And it's been on for days without lag on the same Mac (retina 2014 13").

    It's definitely Yosemite.

    ----------

    No it's not. I daresay it's even worse with newer machines that are retina, because it has to push 4x the pixels. And it's noticeable.

    Mavericks is smoother

    I took the app store as an example because it shows the lagging when it comes to resizing of windows really well.

    I tried the same with mavericks and have to say it is way smoother. Not supersmooth but way smoother. I have both systems installed on this 15" rMBP early 2013 and yosemite is unfortunately way laggier. This prevents me from using it from day to day.

    I enabled the beta updates and I'm checking on performance with every update that gets released. I really hope the can at least achieve the status quo with mavericks when it comes to ui smoothness.

    My advice would be to go back to mavericks or at least have one mavericks, one yosemite partition and use your mavericks as your main OS.

    Its funny that you pick the app that is well know to lag like hell under all known OS X and then just say 'yeah, and this just shows how everything else lags'. What is that everything else? Mail does not lag, Calendar does not lag, TextMate does not lag, Safari does not lag, Messages does not lag. No application I use on daily base lags. Oh! Spotify lags! And iTunes kind of lags, but not really — its difficult to understand whats going because its resize behaviour is so weird.

    Bottomline: it is definitely possible to create a UI that will lag on certain operations. One could even claim that OS X makes it easier to create such UIs, simply because it makes it so easy to build rich UIs in the first place. Optimisation is something the developer should think about. Don't blame the OS for failure to write good application code!

    Here is my experience: MC lags if I have several dozens of windows open. It especially likes to lag if some of those windows are expensive to draw or refresh often. Which makes sense, as MC needs to redraw all the windows in real-time and rescale them.

    Safari works quite well with the sites you talk about. It does lag slightly in tumblr for me, but not on the others. So that must have something to do with the way the site is built. Preview has always been awful with large PDFs and Yosemite certainly did not improve anything here. The PDF engine needs a through rewrite.


    Mavericks worked ok for me, but Yosemite is definitively way smoother.

    Again, if you want to showcase how much slower Yosemite is lagger, sure, talk about it or — even better — make a video. But again, please, don't take the known to be the laggiest app on OS X ever and present it as an ultimate proof that OS X is lagging. Its silly.

    Reminds me of 2011 Android. Just enough lag to be annoying but not hinder my workflow (for me and my usage anyway).

    That was one of the reason I left Android and moved to iOS and then OS X. Now iOS 8 and OS X 10.10 BOTH lag MORE then my old Android device on KitKat and my POS computer at work on Windows 8.

    I don't mind paying more for a product (750 dollar iPhone 6 and 2500 dollar iMac) but I expect a better user experience (then a free on contract Android phone and 450 dollar HP computer).

    Ah well, just venting.

    My rMBP 2014 Iris Pro also behaves exactly to what you recorded on 10.10.2. General very lag UI after a while... Not fixed. Waiting for 10.10.3

    I thought this was just an issue with older machines but i guess not. However, if it's not fixed by now I don't think it will ever be fixed, hopes for 10.11...

    I will say it's nothing relative to the hardware. Hard to believe that an GPU that can handle 3D work but lack of performance to resize a window. Anyway, Appstore shows exactly the same lag on my Mac Pro with HD7950.

    It seems to me the problem is resize by double-clicking-specific. I've never noticed it before simply because I never resize that way. And because I don't rely on resizing like crazy to use my mac anyhow, I see little reason to make anything out of it other than please fix this bug Apple so some of us can move on.

    ----------

    It's coding. It happens on any resolution (retina and non) and using either iGPU or dGPU. It happens with any browser running a loaded webpage such as Amazon, and it happens while running Safari & Chrome on my MBP.

    Scrolling is smooth, switching apps is smooth, resizing to full screen is smooth. Starting apps is snappy. That's all I care about. I can accept laggy double-click resizing as a sad fact of owning a mac if it comes down to that plus having a good OS otherwise.

    Apple menu > About This Mac:

    When you used to click those tabs in that menu, it used to have such bad frame rates! Was so laggy and ugly to look at.

    Seems to be like butter now in 10.10.2! :)

    Didn't have too much issue with 10.10.1, 10.10.2 is smoother on my MBPr 13" 2.8, pretty much everything is fluid so far. Once I am back home I will update the rest of the Mac`s and see how they go, from what I see now no reason not to.

    Yes I have this problem too. I really miss Mavericks. I'm too lazy to downgrade, it would require migrating all my stuff from Time Machine and it's just so damn annoying to do. I just restart my computer every 5 minutes and it's good as new for another 5 minutes!

    I think Apple wants us to buy a new computer every year just like an iPhone, that's why they put OS X on a yearly upgrade cycle: less time for testing, worse performance, guarantees that your computer will feel "old" after a year regardless of what you bought.

    Sorry dude, on my 2012 MBA everything is ok. Nothing you are describing lags on it. On my 2007 imac it KINDA does, yes, but it's still very usable (i use it mainly for work (pages, pixelmator, pdf stuff) and watching Plex. But yeah, mavericks seemed to be a little more fluid. Not that i really care, i mean, it's 7 years old , LOL. But i MIGHT go back to mavericks (if iMessage works perfectly, like it works now on yosmeite, because on mavericks it SUCKED)

    the Mac app store was always laggy so I'm not getting the point here.... I think most the lag is gone with the 10.10.2 update....

    MBA isn't a retina Mac though. Yosemite has graphical lag with retinas, because its drivers are poorly coded to handle all the superfluous transparency and blur.

    Mavericks's iMessage works fine here, just like Yosemite's did. Last time I had issues with that app was when I was on ML.

    I really don't think the drivers are the case. I think it's problems with the apps themselves, but since 10.10.2 I haven't had much lag issues.
