    Many thanks for your suggestions. I did an OS X Recovery; it only let me Verify (not Repair), but it found no errors. The only apps that start on booting are Apple Mail and iTunes. I am still seeing a considerable slowdown from 10.8. It takes longer to open apps, and within apps (like iPhoto and Photoshop for example) the delays are very noticable that never occured before.


    I have a pretty clean system with no third party plug-ins other than in Safari.

    I'm having similiar problems, seeing weaker performance compared to ML. I am getting the beach ball for a split second every 15 mins or so. It is quick but I can see it.


    Performance is generally just bad.

    Hi NNeeiiLLL

    Tank you after i check the console i saw that a software call "contr. alt delete" was

    the problem so i delete it and now after 24 hr everything seem ok.

  • ElectroMac74 Level 1 Level 1


    how yo figure out that this is the problem? it show errors? what a name of the program? can you please just copy past it.

    had you previously long booting time?

    thanks in advance.

  • ElectroMac74 Level 1 Level 1


    i have the same problem on my macbook air, had you tried MacKeeper or CleanMyMac2?

  • Barney-15E Level 8 Level 8

    If you are using them, they are likely the problem.

  • Allan Eckert Level 9 Level 9

    Either one of those will only make the performance worst.



  • ElectroMac74 Level 1 Level 1

    NO they are expensive, they may help, my macbook air boot in 50s which is a lot for an SSD, may something is broken. if your mac is slow at start up too, the solution may be in "slow boot forum" independant from OS X version

  • Barney-15E Level 8 Level 8

    They are expensive, but they will not help.

  • ElectroMac74 Level 1 Level 1

    you're right, CleanMyMac offer  500MB of files removing, it was enough for me, it doesn't help.

    i think we should look for  "slow boot time" on the forum, it may help

    I am not certain if you understand the comments others made about CleanMyMac.


    Using CleanMyMac is likely to result in system corruption and may explain the problems you described in this post: Mavericks too slow


    I recommend you erase your system and rebuild it. Replacing a PRAM battery won't fix the problems that may have resulted from using CleanMyMac to perform amateur brain surgery on your Mac.

    i have to stop believing the ads and wait for my battery.

  • Puharteago Level 1 Level 1

    Yep. Mountain Lion was blazing on my late 2012 iMac i5 27 incher and after Mavs... slow.


    I open up my hard drive on the desktop, and the window is blank and in the lower right corner its doing that little spin thing icon... as if I'm loading a server I'm like what the???


    Saving a document to a location is also a waiting game.


    I'm in the Finder and I create multiple fresh untitled new folders with command-shift-n and there's a lag, I mean c'mon!


    I'm seriously thinking of reverting to Mountain Lion.


    This is my home mac and I have my other iMac at work, NO WAY am I going to install Mavericks on my workhorse 2010 iMac 27 i3... NO WAY.

  • sjordi Level 1 Level 1


    awful for me too.

    Macbook Air 2012 4Gb RAM..


    Clean install result:


    Startup time to login screen with ML: 9s then 2 sec to be able to work

    Startup time to login screen w Maverick: 67s then 17 sec to be able to work



    Memory management? Disaster.


    I use VMWare Fusion 6 to run a Windows 8 machine, using 2.5Gb RAM


    ML: Can use it most of the time.  Memory always available.

    Mav: Can use it only if I run it first. If I open Macmail or Safari, exit them, then run the terminal, send the "purge" command, I can't use VMWare Fusion anymore. It tells me that only 1.9Gb of RAM is available.


    What about the gloat that 4Gb "feel like" 6Gb thanks to memory compression algorithms? Should I enable it somewhere or is it native?


    Anyway, answers are just for the beauty of the science, I reverted my two mac to Mountain Lion wihtout hesitations.
