I am running 10.10.3 on a 2011 iMac and Yosemite runs great on it. No UI lag and no WiFi issues. Not sure what issues you were having running Yosemite on your 2011 iMac.


He must be a ridiculously unlucky guy and gets every Apple devices with problems. If we measure that from the quantity of Apple hate he is spreading on all his posts...

OMG!!!! My laptop was lagging since the day I got it. 2012 15" rMBP. I reformatted 20 times. I just updated to El Capitan (not even a clean install) and my laptop is buttery smooth for the first time! Its amazing. I am so shocked. There are still some issues loading pages in Safari, but if its THIS smooth in beta 1, the full release is going to be mind blowing!!!!

Is this with the Intel HD 4000 iGPU or the Nvidia GT 650M dGPU?

Also with or without transparency?

Yeah. This is indeed snappier. It's crazy how a new high end flagship Mac could lag with Yosemite. But now with El Capitan it's like it's brand new again. Like with the iPad Air 2, the software that really makes them shine was lagging behind.

Thought I'd come in and clarify a few things that have been said in this thread and others. There is indeed much less lag and things generally perform great but retina macs are still struggling with transparency in some cases (try opening the reader sidebar in safari when in the top sites page and look at the frames, or try simply swiping between spaces with this screen open). Also there is still lag in plenty of areas including iTunes scrolling, grid stacks in the dock and most annoyingly, PDF scrolling. The OS X pdf scrolling performance continues to be atrocious, lagging behind what my cheap android phone can do with the same files. Something really needs to be optimised there... Apart from that, the performance upgrades are very good.

Not seeing the lag with the reader sidebar (other than an understandable lag loading the Twitter recommendation tab). But iTunes scrolling lag seems to have been actually exacerbated (not that it was ever butter smooth with my 75K+ collection in any case). iTunes is getting an overhaul with MUSIC in any case, so hopefully that will be addressed. Not seeing any problems with PDF scrolling either. Almost full screen 5K retina, graphics heavy PDF scrolled with a pretty smooth, non-jerky feel. It scrolls better in QuickLook than in Preview though, I'll give you that.

I just find it frustrating when I see people on their iPads flying through PDFs with absolutely no lag, then I try to scroll to the page I need on my rMPB and I'm hitting about 3fps.

I have El Capitan on a 50GB partition on my factory standard 2012 MacBook Pro (i5 2.5GHZ HD4000 4GB Ram 500GB HDD) and I must say its much much faster than Yosemite, even when I've done a clean install of Yosemite it was never this quick.

All visual effects are on on my El Capitan partition, and are off on my Yosemite partition and its still faster, when Public Beta is released I will probably delete my El Capitan Partition and use it as my main partition as Yosemite sometimes is so slow it becomes unstable.

My mouse disconnects erratically in Yosemite, even in 10.10.4 But interestingly enough it only happens with the magic mouse not the mighty mouse o_O

Try wrapping your batteries so they are held more tightly. Worked for me!

Again, that's your opinion... That's not facts. ;) For example, I've never had stability problems. Be it with Leopard or Yosemite. And my battery life remained the about the same trough the OS X and iOS versions. Every point that you make can be counterargumented based on ones experience.

And that's your opinion, it's a fact plenty have stability issues with Yosemite.

I'll wait for the video upload comparison before believing anything you guys say. I've seen this "OMG it's smooth, fast, stable...", but once released, no such thing really occurs. lol

In general usage it isn't obviously faster, tried Adobe CS6 and seems the same too. I've not noticed any "wow that's quick" moments.

Really? All of my Adobe CC apps are opening at least 2x faster.

I didn't know there was a Snow Yosemite....

It's a pun on Snow Leopard's performance improvements on its predecessors.

I like it a lot better than the stupid El Capitan name. But hey, us East Coasters look down on California almost as much as they look down on us :)

And how it is?

OK. I did an over the top upgrade from 10.10.4 B3. It KPed once, then I just woke it up and was brought to another crash error. Beach balls here and there. I'm gonna do a fresh install and restore via TM. Maybe that'll help.

I did notice my battery life has been better under El Cap.
