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

Does anyone can give me hope for an update with a lag fix, so i won't sell this beautiful thing with its beautiful display and get me an older one? 😟 Were there any problems in the past with a laggy UI on the normal macbooks!?

Actually the new update 10.8.3 has new graphic drivers and tweaks its been seeded to deva right now and in the description apple tells dev to focus on graphic performance so maybe this is the update we've been waiting for, this is annoying but not as annoying as the keyboard that comes with this machine Godddd it is bad!! Anyways back to the topic this update should do it if not well have to wait for the next os that comes retina optimized , because the truth of the matter is that its too much work for the GPU to handle

This is more of a software issue rather than hardware. The choppiness and lag is not only noticeable on the rmbp but across other laptops runing mountain lion. After updating my mbair I started having identical performance issues as I have on my rmbp. They are less noticeable on standard displays because there is no resolution scaling, but still happens nonetheless.

Furthermore, if you run windows at 2880x1800 on your rmbp you will have absolutely no lag. Therefore the hardware is capable of operating at such resolutions, it just shows that mountain lion is poorly optimized.

If you decide to swap your retina mbp, I strongly suggest you go for a second hand mbp with lion or an older system. I know that this is not an ideal solution to the problem but if you want absolutely no lag, stick to the older OS.

Not much we can do but wait for an update from Apple.

i can't imagine that apple would sell something, if the hardware can't take the work. so i realllly hope it's a software issue

I am also getting fed up with the lag issues on the rMBP. My friends 4 year old 13'' runs more smoothly than my 15'' rMBP, and it is incredibly frustrating to look at haha. Like, I'll use it for some time, think it's ok, then I see his computer again and mine is like it's going in slow motion, even though it has almost 4 times the power .

apple: in 10.8.3 there will be a focus on better performance, better graphic drivers and safari. i hope so..

did apple give an official statement on the ui lag yet?

I really hope there will be a lag fix for the macbook pro retina version... It will make this machine much more perfect than what it is!

Although it seems very weird to me that the engineers couldn't notice this huge lag problems when they built this machine!

Anyone tested the latest 1.8.3 beta seed ???

Isn't 10.8.2 beta enough? 😉

Update from Apple Support today: "We are aware of it. Wait for update".

10.8.2 For the MacBook Pro Retina? No. It's not possible to work on high resolutions, too laggy! That's why I asked if someone sees an improvement with 10.8.3 latest beta see

Apple released an SMC and graphics update yesterday for the MacBook Pro and the retina.

Ohe? I haven't notice ... Gonna check it out!

Nope, this updates are for the MBP 2011. Not for the Retina MBP.

It is for the retina as well, I have a retina 15".

Where I could find it ? in AppStore only XCode update become available.
