Ever since i updated to mavericks my computer has become slower than when i was on mountain lion... For instance i just restarted my iMac this morning and just about 30 min ago i got down to 0MB free ram, Screen Shot 2013-11-03 at 8.29.23 PM.png as you can see here...

And this has happened about 5 times since ive had mavericks and the only way to fix it is by restarting. Other things like sleep and wake takes forever and when im gaming it makes me get major lag spikes... Im on a 21" mid 2011 iMac with 8GB ram.

    Not enough available storage space can slow your Mac down ...


    Click your Apple menu icon top left in your screen. From the drop down menu click About This Mac > More Info > Storage


    Make sure there's at least 15% free disk space.

    Carloyn, as you can see in his screenshot, he has 1TB free space.


    I also see a lot of unused memory in my system. I have tu use "purge" in terminal to free it up.

    How are you using 'purge' in terminal? I tried it and received the error "

    Unable to purge disk buffers: Operation not permitted"

  • ltaa09 Level 1 (30 points)

    I have hotspot shield uninstalled at least is should be.... And i use google music manager... i shouldn't have to sacrifice things i use daily just to make my computer go better because apple made a unstable release. Also can you tell my how to uninstall is i was pretty sure i did but i guess not.

  • ltaa09 Level 1 (30 points)

    if your seeing hotspot shield from boot up items it wasnt actually in there is said unknown so its gone now..

    Mavericks manages RAM far differently than previous versions of OS X. Your memory monitoring utility likely is not accounting for this and needs to be updated. Note that it shows only ~2GB of used or active RAM, so it ought to do some subtraction of sorts from the total usable RAM. Additionally, a reading of exactly 0GB is generally suspect, especially if you cannot change it by quitting all applications or otherwise manually adjusting the memory load on the system.


    Try opening Apple's Activity Monitor utility and choosing the Memory section, to see what the memory usage statistics are there, and compare this to your third-party monitor. My guess is that Activity Monitor will show you an abundant amount of memory available.
