I downloaded Mavericks this afternoon and installed it on my iMac i7 24GB RAM Everything seems to be slow in transitions from one app to another and many apps stall for severeal minutes as if the processor is playing catch-up. Thoughts? Should I just reinstall the update?

HI There, There are a lot of good solutions in this thread. Check the console to see if there is something running that is zapping the response time. Run disk permissions from the recovery mode and check to see if spotlight is running. This may slow things down a bit while making the initial index.  I'm starting day 3 with Mavericks and it is running smoothly now. Initially, many of my apps were slow starting, but now all seem to be running and starting as they should.  Thanks to all of you that contributed solution offerings.

I had the same problem, installed Mavericks on Mid 2012 Macbook Pro and my machine slowed down horribly, also my battery was showing much less time than normal... I did a recovery and reinstalled Mavericks again and everything is running perfectly... just had to re-authorize some of my programs, otherwise all seems perfect so far! the following is taken from this page: hold down Command-R during startup and OS X Recovery springs into action. It lets you choose from common utilities: You can run Disk Utility to check or repair your hard drive, erase your hard drive and reinstall a fresh copy of OS X, or restore your Mac from a Time Machine backup. You can even use Safari to get help from Apple Support online. And if OS X Recovery encounters problems, it will automatically connect to Apple over the Internet. Hope other find this works for them too! Good luck!

I am having multiple issues after upgrading as well, first Finder kept crashing every few seconds, hereafter multiple small issues. Most of them could be solved by upgrading 3rd party applications. In order to find the culprits of your slowdowns, open up the Mac OS X Console and keep an eye on the messages that keep popping up during use. The the printed strings often have the name of the app or you can do a quick online search.This way I was able to find several 3rd party utilities which were causing problems and updating or disabling them made my Mac feel a lot faster. Good luck!

    Is it still indexing spotlight? 


    Could be third party incompatibilities. Any system "enhancements" installed.

    Same for me. I have an MacBook Pro 2.53 ghz intel core 2 duo, 4GB Ddr3.

    After installing mavericks everything is moving slow. Safari won't open, I have to force quit several times before it works, mail also ...and every click is just taking time. I hope there is a solution if not I have to go back to lion...hope is possible. Please let me know if you solved your Mac problems


    Thank you

    No, spotlight is not running. There have not been any ods to the OS or software.

    I'm about to reinstall ML again. I'm trying to download the full install of Mavericks in the hopes that will speed things up.

    My iMac started running slower than normal with the 10.8.5 update.  Installed Mavericks today and it seems slower, to me as well.  I'm running a mid-2007 Intel iMac 2.4Ghz Intel Core 2 Duo with 4GB RAM, 320 GB HD.

    I know one day I will upgrade the hardware, in the meantime I shouldn't experience this kind of slowness.


    It also periodically stops recognizing my Harman Kardon USB speaker system, even though I set it in the Preferences.  I have to unplug the USB and then re-insert the cable.  My Cubase 7 doesn't recognize the speakers under Mavericks.  Everything was working fine under Mountain Lion, except the slowness at times starting up apps.  


    I think Mavericks killed my computer.  :-)

    For every main OS upgrades (ie. ..., 10.7, 10.8, 10.9. ...), you should do a clean-install so your machine can run like a newly-bought machine beacuse there are an old system caches stored on your machine from the previous version.


    Hope this helps.


    PS. I'm downloading it for my MacBook Aluminum Unibody (late 2008) with 2 GHz Intel Core 2 Duo, 8 GB DDR3 RAM and 160 GB HDD. I will post my result after the installation is fiinshed.

    Mavericks seems to be very very disk intensive upon first startup, let it run for a while, then evaluate it.


    MDS/Spotlight seems to run at the max when first booting. Just be paitient and wait for it to finish.


    Now, I am +30 minutes running, everything has settled so now to start testing it.

  • dmschwartz Level 1 Level 1

    Thanks for the suggestion.


    It will be a royal pain to have to do it, since I have a TON of applications installed.  But you may be right about the clean install.  Probably about a day or two's worth of work ahead of me if I do the clean install.  Never had problems with previous generations of OS X upgrading - Except when they dropped Rosetta in Mountain Lion or was it Lion?  and some of my apps no longer loaded.  :-(


    Doesn't Mavericks looks to see if you have a previous version of OS X installed??

  • dmschwartz Level 1 Level 1

    Let us know how your tests go, chattphotos.

  • Brian Campbell3 Level 1 Level 1

    I hear you and that would be ideal, but it was an update from Apple that we ran. I have been running for a few hours and seems to have no changes at this tie.

  • Brian Campbell3 Level 1 Level 1

    I tried to reinstall ML and it wouldn't let me do the install. Kinda stuck until I can get the full download of Mavericks. Current, my FCPX will not work either. Thoughts?

  • Longhornswagger Level 1 Level 1

    DobaKungThanks! I'm definitely interested to hear your results.

  • DobaKung Level 1 Level 1

    Okay, here you go.


    I, finally, installed OS X Mavericks successully after facing the Mac App Store error. First, I used 'Upgrade' method to test the performance. My Mac runs smoothly and faster. No problem appears and everything works fine. I will do a clean-install now and post a result again as if it would run better.

    What do you consider a "Mod?"

    I was referring to anything that added a startup item, status menu, launch daemon, or kernel extension. Essentially, anything you had to use an installer to install.


    Any of that kind of stuff can cause issues. However, if it worked in Mountain Lion, it will likely work fine in Mavericks.
