Is Yosemite running smooth on your MBA?

I don't understand all the people complaining about performance problems. All talk. Let's see some proof?

I'm not convinced. Either that, or they're running Yosemite on old hardware?

First, here's my proof:

I didn't necessarily call you a liar. Though you seem awfully offended for some reason. I just want some screenshots that demonstrate your problems. Otherwise, what you say means little. You could just be another internet troll.
 
Yosemite is good here too

I have Yosemite installed on my 2013 iMac 14,2 i7 3.5 GHz 24 GB RAM 3T Fusion and my 2012 MacBook Pro 8,2 i5 2.5 GHz 8 GB RAM 256 GB SSD and it's running solidly. Both machines seem to be running quickly but they both have SSD start up drives and plenty of memory. Only 2 problems I've noticed neither of which makes Yosemite inoperable. The files in the Finder still disappear from view especially while deleting other files. That should have been fixed by now since it was reported as an issue way back in beta 4. DropBox v2.10.31 crashed on me once. No version of DropBox has ever crashed on my computers. I have upgraded to their v2.11.29 beta and no problems so far.

I cannot stress strongly enough to backup before you install then do a clean install, maybe even reformatting the HD first then enter all preferences and install all applications freshly rather than doing a migration. I know it takes lots of time but it is always a good idea to start completely fresh when doing a major upgrade like this.

I certainly agree with that. The upgrade went smoothly on my MBA. I used a Yosemite installer USB stick that I created. But, on my Mac Pro, on the first attempt at upgrading to Yosemite, on a disk that had the all six public betas installed on it, the disk got corrupted and couldn't be saved. It was necessary to wipe the SSD and start over. I have 8 storage devices on the Mac Pro (2 for the MBA) so I have backups of everything. I copied a backup to my Boot SSD and then retried the update process with the USB stick, and smooth as silk the second time.

Ram

I was running it for a few days before i clean-installed the Mac. It was using all my ram when nothing was open! Anyone else having that problem?

peace :apple:

On my end, the system (2012 MBA, see etrecheck.rtf below for details) is laggy *without* having a high system load. As I mentioned above (https://forums.macrumors.com/posts/20230908/), the system works fine for long periods of time until I load up Preview.app with a couple PDFs. I did an experiment yesterday. I had used my MBA for two full days running all sorts of applications (Safari, Firefox, MS Word, Numbers, VMWare View, iTunes, Mail, Calendar, etc.) with everything being smooth and responsive. Then, at the end of the day yesterday, I opened up 5 PDFs in Preview.app. Almost immediately, all animations became laggy. The lag persisted even when closing out of all running windowed apps.

Here is a snapshot of the system at that point:

By all accounts, the system is idle. However, animations (e.g., switching desktops, etc.) are terribly laggy. Again, everything was smooth for two days prior to firing up Preview.app. I really do think the GPU drivers or WindowServer have a problem that Preview brings out.

That's rather strange! Thank you for providing such a detailed reply!

I did notice similar behavior on my 2014 MacBook Air. That's not to say I had laggy animations. I noticed that WindowsServer and its respective kernel_task was using a lot of RAM.

Here, I opened up 4 different files in Preview.

Been hearing stories about the animations/scrolling being jerky/laggy due to the transparency. I heard turning off the transparency helps, but that isn't a solution in my mind. Any truth to this?

I tried the below and the performance improved. Tks!

Delete /Library/Preferences/com.apple.windowserver.plist
Delete ~/Library/Preferences/ByHost/com.apple.windowserver*.plist
Shutdown OSX
Startup, immediately press and hold the P and R keys while holding down the option (⌥) and command (⌘) keys before the gray boot screen appears, which resets the PRAM

I turned it off, because I really didn't like it🙁

Ditto. System seems to be idle, no load, no stress no nothing. still getting inexplicably laggy.

I kind of want to do a clean install but I don't want to go through the hassle of backing everything up and reinstalling everything. First world problem if I ever had one.

Is there any connection between deleting the files and resetting the PRAM? Or why specifically these two things (and in combination if I understand you correctly)?

since I shut mine down twice everything is running fine. I wonder about the talk above about the preview pdf? is that iCloud drive related? because I opened and viewed a pdf from iMessages the other day and that opened pdf viewer (is it) in iCloud drive. I wonder if that was why my machine slowed.

My emails i have deleted and reinstalled but two keep loosing the connection, resetting SSL and just annoying the **** out of me. Apart from that I'm all good....for now.

I did this, and I have had promising results. I had previously reset the PRAM, so deleting the plists was new.

I just fired up Preview with 15+ PDFs (along with almost all of the ~15 applications in my doc), and my system did not get into its normal laggy state. We'll see how things stack up with some more long-term use.

*fingers crossed*

I can confirm that for me the laggyness seems to be triggered by preview.app especially with complex pdf files.
I work a lot with architectural drawings and my macs become almost unusable when trying to open such drawings.
I can reproduce the issue on my:
MBA mid2013
MBP Retina late 2013
iMAC 27 2013

On Mavericks the zooming and scrolling of the files works just smooth as butter.
Here two exemplary pdf files, I would like to receive some feedback specially from the people having no issues:

On my 2012 MBA, Preview is nearly useless for scrolling/zooming these PDFs (it mostly just gives me the pinwheel). However, the overall system lag/sluggishness does not appear to be getting triggered (possibly due to my previous deleting of plists and resetting of PRAM, reported in https://forums.macrumors.com/posts/20260309/).

Thank you for your feedback. I tried the plist deleting and PRAM reset and the system lag seems to improve. However preview.app is still buggy and unstable.

Btw I have also noticed a deep reduction in battery life (from 9hs to 5 in my rMBP and from 12 to 7 in my MBA), may be it is related to the CPU and RAM overload caused by Preview.app.
 
Preview seemingly cannot handle a ~5mb pdf file anymore. Its not even jaggy when scrolling it just jumps around without showing much of a movement.

CPU load does spike enormously and goes up to 100% momentarily. It's never been like this on Mavericks.

Got a MacBook Air recently, and first thing I did was wipe and install Yosemite. I'm incredibly happy with the computer and how well things are running, which is why one small glitch is incredibly annoying: in iTunes or Quicktime full screen playing a video, the fade in animation for the player controls (i.e. if I move my mouse to bring back the controls), the video completely glitches out for a split second during the animation. It's sort of difficult to describe the glitch, but imagine V-sync tearing x10000. This doesn't happen during the fade out animation of the controls, or with say HTML5 video controls.

Anyone else experiencing this? I can't think of anything special about my setup that would cause this.

On my MBA 2012 those PDFs works without any issues (scrolling, zooming, doing some other stuff).

Beside an initial WiFi issue (that I resolved) everything else seem to work just fine with Yosemite.
 
Only problem i have is notification center using 150% cpu and fans go crazy i have to kill it via activity monitor ..

anyone know how to turn off notification center?
 
Yosemite runs perfectly for me on my 2013 11" MBA except for one issue, battery life when transparency is on. With it off battery life is the same as in Mavericks but with it on, it's reduced by about 50%.

I also ran an-place upgrade and at first performance seemed to be just fine. I was able to get my work done.

However, after a few weeks, I noticed more beach balls, lags performance and other oddities, like Finder Preferences not displaying properly, emptying trash would not complete, not able to shut down as finder was busy, etc.

So I went for a clean install of Yosemite and now, things are running even better. Memory management is more robust than the upgrade.

I am convinced that a clean install is preferred to an in-place upgrade.
