2015 Macbook Pro's Intel Iris 6100 is so choppy in Yosemite

I have not noticed any choppiness on my 2015 13".

Also if anyone is curious it can play the Sims 4 on high and plays WoW pretty well.

iStat Menu seems to be another culprit causing major GUI lag. I killed it and I instantly have buttery smooth performance 100% of the time again.

I have istat menu running with no perceivable gui lag on my 2015 rMBP. With that said istat menu isn't fully functional in the new MacBook but that's a different issue the dev is addressing.
 
Well, just tried the laptop out on a 1080p external display and it is unusable. So laggy I can't do basic work. Taking the laptop back for an exchange.

I can't believe it but this totally eliminated the jittery GUI! Just shows how badly Yosemite is optimized.

Yeah, it fixed it. I'm really hoping they optimize the software. I am chromecasting a video in my Chrome browser and when I try to render pages, you can kind of see a gray/white checkerbox that lasts maybe 1 second. It's weird cause you would think the 6100 would be powerful enough. I didn't have this problem on my cMBP. I was thinking of dishing out and getting a 15'' but that would require a significant more amount of money as it would require a dGPU. Not sure if there is an answer to this other than Apple optimizing Yosemite.

They are going to have to do something about it now that the paper thin macbook slouch is about to be released.

just to give an update to my situation.

after my fresh install my rMBP is working perfectly.
Click to expand...

So, I am trying to do this (I have done it many times before).

App store won't let me redownload Yosemite saying that it's already installed on my computer. I have no problem redownloading it on the cMBP.

I get a crossed out circle when I try to boot from the USB when I reboot my computer. The cMBP has no problem booting from the USB.

Is my only option to go to the Apple store and ask them to clean install? I'm getting pretty annoyed with this machine...



It appears it may be due to FileVault being on. I wonder if this is causing performance issues. I only enabled it cause the laptop was new. Will turn this off. Will see if this improves performance.

And I can't install from this USB drive despite turning off FileVault and being able to install from it on my other mac. Any solutions?

In my previous mid 2014 rMBP (my first Mac) I enabled FileVault during initial setup and it remained stuck on "encryption in progress" and I couldn't turn it off or disable it and I think I couldn't enable the built in firewall with it stuck. In either case it annoyed me to no end so I wound up trying many different "remedies" I read online only for none of it to work. Eventually I just wiped the hard drive and reinstalled the OS. I did the reinstall per the instructions below and it was a cinch.

With my new 2015 rMBP I didn't bother enabling FileVault.

You might be wasting your time, I had done a clean install of Yosemite when it was released, it didn't remedy the jitteriness. FV is an interesting lead, I unfortunately don't have the luxury of time to do trial and error. The only thing that really worked for me so far is the contrast feature in accessibility.

If you think yours is perfectly smooth, you're not talking about the same issue as me and others here, which is - 100% definitely - present on all 13" retina MBPs running Yosemite (and previous OS X versions, for all I know).

Nope, Mavericks is pretty much buttery smooth. Tiny, tiny spikes of lag sometimes with many windows open, but far from Yosemite.

Yosemite looks great and is the best OS X release since Snow Leopard.

With all due respect, you cannot be serious. Yosemite is the worst OS I've used since Vista (or only considering OS X versions, Lion). Even prominent developers and press have complained about Apple's declining quality control.

Here's a very detailed roundup you can consult when time is appropriate.

Not that anyone cares, but I returned the 2015 13'' and got a 2014'' 15''.

Can you install Mavericks on those? I know that you can on the 13" because I have one myself. If you do get around to installing Mavericks, you'll notice the huge performance gain, along with (nearly) no lag.

i do not use file vault encryption. however to clean install i booted up holding the funny apple key + r. erased my hard disk using the utility then connected to wifi and boom clean install.

not sure if that helps you.
 
Man, I don't understand the problems everyone is having. My 2012 Retina 15" running on integrated doesn't have lagging problems, nor did my 2013" 13" retina with 5100 graphics....are you guys that anal or am I lucky. Maybe it just doesnt bother me, I suppose it looks slightly smoother with dedicated turned on, but nothing to write home about.

Sorry, this is not at all being @nal and it is certainly not a question of slightly smoother experience. We're talking MAJOR jitteryness, as in day and night GUI experience between Yos and Mav.
User experience seems to vary substantially but that is probably because of the differing ways that we use our machines. CLEARLY this is shoddy implementation of YOS and I blame Jonny boy 100% for his obsession with eye candy, even if it means sacrificing the overall feel. Shame because i was really impressed with Mav and this doesn't even come close.

yea....sorry I just don't see it, but to each his own... Mine runs smooth as butter.
 
Hey, I'm also having this problem with my new 2015 rMBP 13". Here's a link to a video I captured showcasing the lag: https://www.dropbox.com/s/w1k8lyhx1obex58/lagUI.mov?dl=0

I didn't do a backup restore, instead I cleanly installed all my software. So far only turning on high-contrast mode helps, but I'm not happy with such a gimmick since this is a new laptop and should be able to handle the UI and Yosemite just fine. I'm not a 100% sure if the UI lag was present from the start, I didn't pay attention to it then. So I can't rule out whether something I've installed has caused it or if it was present from the start.


If I understood OP correctly, they were able to resolve the issue by resetting PRAM? Or did I miss something?
Click to expand...

I tried PRAM resetting a few times and many other solutions, but it didn't fix my problem.

Intel just released new Haswell and Broadwell GPU drivers that I expect will greatly improve performance when make it to OS X in 10.10.4 or 10.11.
Click to expand...

Any idea when those are coming out? It would suck to use a hampered mac until then.

It's been with us since mavericks and the transparency in Yosemite doesn't help.
Click to expand...

What's your source? What do you mean, it's been with us since Mavericks? Does anybody whether it's a hardware or a software problem? If it's software, why isn't it clearly fixable? And why is it only present in some Macs? (I presume most rMBPs are handling the UI and the OS just fine and without lag).

My laptop had this issue out of the box (a fresh install with none of my apps installed), so I don't think it was my software's fault. The PRAM reset did work for me, but I did not that it may not work for others.
Click to expand...

Seems to indicate it's a software problem. However, PRAM reset didn't work out for me, so I wonder if I'm just left with trying to reinstall the OS cleanly. That would take me plenty of more hours, of which I'm not happy about. I've already put many hours into trying to figure out what's wrong. Does Apple give out gift cards or something for problems like this?

you prob got a lemon... same specs, 16gb ram, 512 ssd, buttery smooth
Click to expand...

That's what I'd expect, having updated from a 2011 MBA because of choppiness... What's a lemon? A badly preinstalled mac or what? An OSX reinstall would fix that?

I haven't made comparisons with other rMBPs, but I have got the impression that most people have it buttery smooth. What I'm experiencing just can't be normal.

after my fresh install my rMBP is working perfectly.

I guess I should try this, but I really wouldn't like to go through all the hassle if not necessary...

My point exactly.


Ideas?

So today I bought a new 2015 13" Macbook Pro after finally giving up on waiting out Apple for a retina display on my aging Macbook Air. I am experiencing extremely poor GUI performance.

I know that retina displays are taxing on GPUs, but the Intel 6000 series seems incapable of driving this display without extreme choppiness in Yosemite for a number of actions— mission control, switching between windows, opening new windows, etc. This is the most significant lag I've experienced on any laptop on Yosemite. My old 2010 Macbook Pro 13" doesn't lag this bad on Yosemite.

Is this the experience of others here? The performance is so bad that I'm going to return the laptop if it doesn't improve because it severely impedes on the usability of the system. Also it is BRAND NEW!

UPDATE: Resetting the PRAM may fix this issue for you— it fixed it for me.
Click to expand...

Honestly I think you got a defective model. I bought a base model 2015 13" and have no lag at all.

Remember that the Broadwell processors got delayed because they were having issues with getting production up due to it being much more difficult to fabricate. I believe they were having issues with producing processors that were fabricated correctly. You may have gotten a faulty processor most likely.
