Q: Mountain Lion UI Lag on rMBP !!! (Let's Make this thread serious and hope for a fix)

I personally think the UI lagging bug is a serious issue on rMBP because this machine cost $2000 and up and it lags on UI features such as Mission Control and Space Switching while classic Macbook pros don't. I do understand that the retina display models carries a high resolution display, but I think the quad core CPU should have the ability to handle it (please correct me if I am wrong)

 

 

I am hoping and asking anyone experiencing the issue to follow up with this thread and post your concerns. Let's hope for a fix soon and we can really enjoy the beauty a Retina Macbook Pro brings to us.

    I posted earlier that removing Mission Control animation helped the lag.  Well... it did for the first few hours.  But now, instead of a stuttering/fragmented fade-in/out effect, it simply freezes the entire computer for 2-5 seconds and then the desired elements are shown on the screen.  Music (playing in iTunes) also stutters/freezes... so this is not just a visual impact - it's audible as well!  Just pulling up Mission Control actually froze my computer on two occasions for roughly 20-30 seconds.  Luckily I have a 45-day return policy through Best Buy. If it's not fixed within 25 days, I'll just return and get a new one... and just hope it's a machine-specific problem (or at least specific to everyone on this forum) and not one that affects all MBP retinas. 

     

    I'm actually surprised that this machine is so much more laggy and slow when compared to my significantly less powerful MBA.  Major disappointment.

    Using 10.8.2 on MACBOOK AIR MID 2011. Still lagging while switching desktops. I was able to show the problem on the genius bar at the nyc grand central. They recommend me to 'wait' for a sw update.

    Same issue here on a rMBP, no better since latest update. Really annoying, and dissapointing to see such bad lag in apples own programs such as mail and the app store.

     

    Though I've noticed that the app store is lagging pretty bad on my iPad 2 since the ios6 redesign.

    Someone notice delay when you type text in forums or in other forms with safari?

    The kernel_tasks after some hours takes 800-850 mb of ram, is it normal?

    I have also the problem that after wake up from sleep the clock is wrong, I have already report this bug without response.

    Im seeing some considerable lag too. 10.8.2 patch on a late 2011 macbook pro. Intel 2.2GHz with 4GB memory. Today, I had to wait about 10 minutes for the login screen to appear after hibernation. Its ridiculous. I had no such problems in my old mac with SL. It was running smoothly.

    After installing 10.8.2, I don't know why the shutdown time of the rmbp increased from 3-5 secs to 30 secs and it also experiences frequent freezes now. Quite disappointed in this product, really hoping for a fix for this issue.

    After my post yesterday I've been increasingly encountering lag, and most irritatingly so when playing music through iTunes. Randomly when I'm using the computer the music will break up and is jerky. Happens just simply browsing the net.

    My experience: 15' MacbookPro with Retina display, 256 Gb disk.

    This is definitely a bug as it doesn't always happen. I never saw the issue until I've upgraded to Mountain Lion.

    It happens 99% of the time when I plug the external monitor, but also happens very often when using only the builtin monitor.

    When the stuttering occurs animations flash back and forth, it's not just that they are slow. For example when you drag the mouse from the bottom right side of the screen to reach the dock (with dock magnify animation active), you'll see the dock start to magnify, then contract somewhat again, then magnigy again (all within say 0.5 seconds).

    Similarly when doing the 4 fingers zoom to show the desktop, then doing the opposite movement the windows will come back to the center with their edges rapidly flashing, as if the animation frames of the animation were in the wrong order.

    Anyone knows how to officially report this kind of problem to Apple (without having to go to the store)?

     

    Thanks.

     

    Flavio.

    Hi folks,

     

    it seems that the Macbook Pro Retina make serious problems.

     

    My experience so far:

    I've a Macbook Pro Retina, 2.7, 16 RAM and bought it few weeks ago.

     

    I am very shocked with the graphic problems this machine have. Switching to mission control or scrolling in safari or just switching between applications like safari, ical, and mail in fullscreen mode is very sluggish.

    My Macbook Pro 13" Early 2011 in comparison to that had no problems. Every animation was very smooth.

    So I went through the internet for hope that there is a fix but I couldn't find anything yet.

    I also installed the app called gfxStatusCard, which can switch between both graphic cards. So I experienced that with switching to NVIDIA this problems seems to be get better but unfortunatelly not optimized:(

     

    Do anyone know a fix or is there solution by Apple?

     

    Thanks for your helps

    It seems that not all MBP Retina are affected by the UI lag. I will just let test the hardware of my MBP Retina and will report then.

    Hm. That's also a Developer Preview version of ML; I wonder whether anything changed. I am not seeing anything close to that kind of smoothness on my machine.

    I hope that this is just a case of hardware defect. So we could return it back and get a new one. Tomorrow I bring it for a complete hardware test. Let's see. I will report the result.

    I ran the complete hardware test a week ago here, and no troubles found. I think those videos was recorded with the developer preview of ML. Someone has tried how the machine runs with Lion (not ML) ?
