Q: Mac slow after installing Maverick

Hi,

 

as others are reporting, I've got a lot of lag on my Mac after installing Maverick.  I have to keep waiting for things to happen (it's like using my little Windows laptop!!).  Especially Chrome shows this behaviour and Mail.  When I switch to the application or open a tab it takes ages for it to render.  There seems to be a lot more (audible) harddrive activity.

 

Model Name:          iMac

  Model Identifier:          iMac12,1

  Processor Name:          Intel Core i5

  Processor Speed:          2,5 GHz

  Number of Processors:          1

  Total Number of Cores:          4

  L2 Cache (per Core):          256 KB

  L3 Cache:          6 MB

  Memory:          4 GB

  Boot ROM Version:          IM121.0047.B1F

  SMC Version (system):          1.71f22

 

 

ystem Version:          OS X 10.9 (13A603)

  Kernel Version:          Darwin 13.0.0

  Boot Volume:          Macintosh HD

  Boot Mode:          Normal

  Secure Virtual Memory:          Enabled

  Time since boot:          3:16

 

 

thanks for all help

    You have the Genieo adware/malware installed and needs to be properly uninstallled.

    Ditch ALL Googlewares. They are ALL a serious resource hog on the OS X system.


    https://support.google.com/chrome/answer/95319?hl=en


    If you do not like Apple's Safari web browser, download, install and try Mozilla FireFox, instead.

    The current, up-to-date version of FireFox is fully compatible with OS X and is regularly updated by the great developers of the Mozilla group.


    I have, also, stopped using the Google search engine, regularly and use DuckDuckGo as my default search engine.



    Also, what is not helping your Mac, at all, you have install 3 virtual environment applications (VMWare Fusion, VirtualBox AND Parallels Desktop). Running more than one of these can cause conflicts with your system and OS. Pick the best one to use regularly and properly uninstall the other two.


    You should consider installing more.RAM, too!

    Your year and Mac model should be able to take a total of 8 GBs of RAM.

    Correct, compatible and reliable Mac RAM can ONLY be purchased from online RAM sources Crucial memory or OWC (macsales.com).


    Good Luck!

    I found a memory hungry process associated with Chrome - top process in the screen grab below.

    Screen Shot 2014-12-30 at 20.57.31.png

    It was - as you can see - using half of my 4GB.

     

    I did a force quit and the disk paging has diminished considerably and the machine (iMac running Mavericks 10.9.5) is now running faster.

     

    Oh, worth checking this out too regarding Chrome - https://productforums.google.com/forum/#!topic/chrome/LfBqIlfFoSo%5B1-25-false%5 D

    If you just ditch it, you won't have ANY issues with Chrome EVER, again!

    All Google softwares run terrible and have ALWAYS been problematic on OS X.

    Do yourself a HUGE favor and just say NO to anything Google.

    I've got a 2008 imac, appalling after 'upgrading to Mavericks', have 10.6 on a partition so same computer, when I go back to it it's a joy. 

     

    After reading here I ditched Chrome about  2 weeks ago and just use Firefox and Opera - the difference is amazing.  Still slow to start up but at least now it's got back to being useable.

     

    SO - Thank you Thank you Thank you to people on here and to anyone new with the same problem - DITCH CHROME !!!!!!

    Hey guys,

     

    I have a solution that worked for me.

     

    I bought my iMac new and it was running blazing fast, then a month later Mavericks came out so I upgraded to it. I immediately noticed my computer was incredibly sluggish so I tried reformatting and everything under the stars to get it to work.. Nothing helped. I just stopped using the brand new iMac and happened to get a job where they gave me a Macbook.

     

    Several months go by without me touching the iMac. I get a roommate who doesn't have a computer so I tell him he can use the iMac but it's slow. I made an account for him and immediately notice it's very fast.

     

    I make his account an admin, delete my account, create a new account for myself, and voila, everything is fast again. It's that easy.

     

    I suppose some file or data associated with my old user account was the culprit, and every time I tried to reformat it, it kept that data, but by actually hard-deleting the user it got rid of that data.

     

    Hope this helps someone.

    Welcome to the forum, but I'm sorry to say you aren't using it efficiently.

     

    This is a very old thread, I suspect most of the information is no longer relevant and I may be the only one still following it (I'm certainly not sure why I still am).

     

    You haven't fully explained your issue, which is the most important thing you can do. We need lots of detail.

     

    You responded to the OP (the person who started this discussion seventeen months ago) with information he didn't ask for, so I'm not sure anybody knows what it means.

     

    You are always welcome to read through these old threads to see if they offer any information that can help you out, but if you don't find anything it's always best to start your own discussion, again with lots of details describing everything you are experiencing.  You will attract a lot more help faster that way.
