    Hi. I've just installed OS X 10.10 on my 13-inch Retina MacBook Pro. Since I have powered it on for the first time it has always been incredibly slow and unresponsive. Some examples:
    - If I open System Preferences and click on a panel, I'll get a spinning wheel for about 20-30 seconds before the panel actually loads, and sometimes the app crashes
    - It takes 15 seconds of spinning wheel to trash an *empty* folder
    - iTunes takes about 30 seconds to open (vs. less than a second in Mavericks)
    - I opened 5-6 tabs on Safari and the fans started spinning very fast and loudly (I have never heard the fans in Mavericks) and the computer started becoming hot
    - I can't do Time Machine backups as it takes about 1 minute to backup 100 mb
    - 97% memory is in use, basically without doing anything. Purging it didn't help.
    I also can't turn the volume up and down (I get a prohibitory sign).

    I checked activity monitor and I see that WindowServer is taking 40% CPU, which I don't think is normal.

    Can you help me? Do you have a similar problem too?

    I really do not want to be that guy, but backup, erase, and try again.

    Clean install or did you upgrade?

    I did an upgrade, but I haven't spent much time with it so I can't confirm it's responsiveness. Most of the time it is better to do a clean install as some of your programs might not be compatible and may cause issues.

    Just wondering... You know that this is Developer Preview 1 right? That means just that, it's a Beta version, not every thing it going to work right, or work at all. So the slowness you are getting is because it's not a finish.

    If you installed this on your main drive, you should restore from a backup (you did do a backup before you install the OS right?), then try to install again. Maybe this will give you better experience. :confused:

    I know that this is just the first developer preview, but I think that such a slowness was never seen even by Apple employees in early alpha versions! It must be something else. I'll try doing a clean install.

    Everything appears to be working even faster for me than it was under Mavericks. Apps that normally took a long time to open like Messages and iTunes are now opening in half the time. Very pleased so far!

    I'm not experiencing any performance degradation. It's a fast as Mavericks. When i first installed it the RAM usage was ridiculously high, but that seems to have settled now (probably all the background optimisation stuff).

    Sounds to me like it's just Finder doing the complete disc re-indexing it always does when you install a 10.X-update. The obvious sign of this is a pulsating dot in the middle of the Spotlight magnifying glass and in 10.5-10.9 at least when you click it, there's an "Indexing: X minutes left"-text and a progress bar.

    Actually DP is even more like an Alpha than Beta. Beta versions are more advanced by the naming scheme than DP or Alphas.

    Funny thread. Some things to note:

    1. This is DP1 - very early and Apple likely hasn't done extensive testing on all the different machines and software that customers use.

    2. Apple specifically warns people to back up their data and recommends not to install on a personal/production machine.

    3. Most important part: You need to be a Dev to install it, and if you were a Dev you'd know that you aren't allowed to talk about DPs publicly on sites like this. :)

    I did an update from Mavericks on my 2014 13inch MBA 4gig of RAM and it runs quite quickly.

    1. I'm not complaining of the developer preview. I encountered a problem and I'm just asking if it's a /my/ problem or not.

    2. Indeed, who says I don't have a backup? And who says this is a personal machine?

    3. I /am/ a developer. But even if I wasn't I could have installed Yosemite anyway. You may not know that Apple now allows people not enrolled in the OS X development program to test Developer Previews.

    The DP is not part of the open beta program.

    I am also not experiencing any serious performance issues. I'd recommend a clean reinstall.

    Actually, anything that was mentioned during the keynote is considered not to be under NDA. So the new interface, transparency, Continuity, Handoffs, etc are all fair game.


    You still have to pay the annual fee to have access to the Developer previews. The public beta is completely separate from the DPs, and hasn't even launched yet.

    Mine was like this at the start but once Spotlight indexing was complete things became a lot quicker!

    That's 100% not true. Where is your proof of this claim? Apple doesn't "Allow" that, they just may not come after you if they discover you're not a developer using a DP.

    Can your speakers output sound ?

    If not, try this :

    I can't say why, but it has fixed all the sluggish that I've had before. I couldn't even use the OS. Safari would hang all the time, System Preferences too, Finder same thing, Google Chrome and Firefox wouldn't work ...

    We should have that saying like...framed or something.

    "It's a beta"

    Same Thing, Found Culprit

    The culprit chewing up my CPU on Yosemite was the Parallels Access agent. Set it to not start at boot and quit the program and the issues go away.

    Installed on my MBPro 13", late 2013 w/512 SSD. No issues. Upgraded my Mavericks install that was upgraded from Mountain Lion. Everything is running smoothly and I am really liking the interface.

    but you report the problem directly to Apple through their bug reporting website. So far I've reported 5 bug an received a response on what to do next.

    Also, built in to this DP, it automatically reports back to Apple about your system and apps installed anytime there is a crash, system freeze, kernel panic, etc.

    Also, I was not aware that Apple currently allows the public to use Yosemite DP1. Interesting, how does everyone go about getting it from them ?
