Lost 2GB after upgrading to mavericks

Seems that I need to ask Apple to credit part of my new MacBook AIR purchase !  I lost 2GB after upgrading to Mavericks.  Used to be at over 6GB of RAM after booting before running my apps, now I come to the same point at 4GB !!  Anyone else have the same issue.  I changed nothing else !

normal, RAM USE CHANGED in Mavericks to make it better
Mavericks is designed to use RAM differently for good reason. Normal

Mavericks uses RAM much more efficiently than any other previous version of OS X. Mavericks now has a memory compression feature that will compress the memory occupied by applications that aren't being actively used and give the freed up RAM to the application that needs it the most.

  • I've lost aperture after upgrading to maverick, common apple this is my livelihood.

    i've lost access to aperture after upgrading to maverick, my livelyhood is tied up to aperure let alone all of my photographs for clients, come on apple don't do this again.

    I tried the link leonieDFsent (http://support.apple.com/downloads/) and was unsuccessful after several attempts at the launching of the applications after download. Not sure why?,
    christopherakapaul, the downloads page has update installers, not stand alone applications.
    Any Aperture version you download from the Support page will have to run and to install the update to Aperture. For this to work, you need to have an older Aperture version in the Applications folder, and Mavericks must allow the installer to run. For some installers the security&priivacy settings in the System preferences need to be disabled.

  • I've lost iPhoto after upgrading to Mavericks. I try downloading and it says I have an older version then doesn't give me an option to do anything?

    I'm trying to download the new version of iPhoto when I upgraded to OSX Mavericks. It's telling me that I have an old version of iPhoto but yet not giving me an option to download new. Any ideas on what may be the problem?

    What version of iPhoto do you have?
    If you have any version of iPhoto '11 then version 9.5.x is a free update - if you own an earlier version of iPhoto ('09 or earlier) then you must pruchae iPhoto '11 version 9.5.x in the app store

  • 2GB MBA (2010 version) Out of memory after upgrading to Mavericks

    I'm using a 2GB MBA (2010 version). After upgrading to Mavericks, I have very little ram left (<50MB). I can't run anything. Even the Internet is breaking up. Safari won't load anything. I get to some webpages using Chrome if I'm lucky... is it normal?

  • Why did my mouse stop scrolling after upgrading to mavericks?

    I have completely lost all ability to scroll with my Apple Magic Mouse after upgrading to Mavericks.   Why did this happen?   How can it be fixed?    It worked fine with Snow Leopard and Mountain Lion. 

    Everyone:
    I was able to solve my own problem, after scouring the Internet looking for solutions.  Sadly, the Apple Support Community was of no help. 
    Here's the full story:
    I originally had purchased my iMac with Snow Leopard installed.   I loved it just the way it was, and really did not ever want to upgrade.  However, I've been around computers long enough to know that I would HAVE to do it someday, only because of the age old problem of wanting to run some new application in the future, but not being able to, becasue the app would only run on the latest version of OS X.  I reluctantly upgraded to Mountain Lion less than a year ago, without too many problems -- nothing I wasn't able to fix fairly easily anyway.  When Mavericks came out, with the "offer I could not refuse" price of FREE, I knew I would eventually have to install it. 
    So the day comes when I'm finally ready to install Mavericks.  To get ready for that day, I did the following:
    I ran CCleaner on Mountain Lion to clear out any old files accumulated.  (No longer works in Mavericks)
    Made sure my Time Machine backup was up to date
    Cleared out gigbytes of old files off my hard drive, and archived them on an external USB drive
    Made sure every single app on my iMac was fully upgraded.
    Made sure Mountain Lion itself was fully upgraded! 
    I then set aside a full day for the upgrade, knowing full well how long it could take, even with a very fast internet connection.  Eventually I worked up the courage to go to the App Store, and proceded to download Mavericks. 
    The update seemed to go smoothly enough, no problems that I noticed.  So I finally get to the point where I can sign on to my iMac again, opened up the Chrome browser, and found out that my mouse was was unable to scroll.  I then opened up Firefox and Safari, and found that I could not scroll pages on those browsers either. As a matter of fact, I couldn't scroll using my mouse no matter what app I tried.  That feature was completely lost.  
    I went to ' System Preferences --> Mouse ' to look at the settings, and only the most basic settings were available: click and speed, nothing at all for scrolling or swiping.   That's not good....
    Looking to see if anything else was missing in System Preferences, I saw that there was no option for Blue Tooth at all.  As a matter of fact, Blue Tooth was completely inoperative, and there was literally nothing I could do to make it work.  The Mavericks upgrade had completely trashed Blue Tooth on my iMac.  I have no idea how my wireless keyboard and Magic Mouse were even operational, Apple must have some sort of "back door" that keeps those two connected even when the entire Blue Tooth subsystem is off-line.  
    Since there was absolutely no way to fix this, given the damage done by the Mavericks upgrade, my only choice was to do a complete re-install of Mavericks.  I did this by turning off my iMac, and then after turning it back on, I held down the command + R keys to initiate the "recovery" of my iMac, and re-installed Mavericks. There are screens the are displayed that walk you through the process, which is fairly easy and strait-forward. 
    This above process is a feature called OS X Recovery, and it has been present since Lion.  Here's a link to an article that explains it more fully:
    OS X: About OS X Recovery
    http://support.apple.com/kb/ht4718
    I did not know about this feature, but found out about it after doing various web searches in an effort to find a solution to my problem. 
    So, I basically ended up installing Mavericks a second time.  This took hours to accomplish, but it worked.   After the second installation, I signed on, and sure enough, Blue Tooth was back in operation, and my Magic Mouse worked without any problems what so ever.  I had full scrolling ability in all my apps.  
    So OS X Recovery saved the day, at least for me. 
    I should note that before doing the Mavericks upgrade on my iMac, I had already performed the upgrade on a family member's MacBook, without any problems encountered at all.   They were still running Snow Leopard, the orignal OS that came with their MacBook!  Like me they were reluctant to upgrade, but eventually it becomes a necessary evil. 
    Here's hoping that this information may be of use to someone in the future.

  • Macbook slower after upgrading to Mavericks

    Hello, I'm owner of a Macbook Pro MD322LL/A and I haven't had any issues with Lion (the OS that came with) but after upgrading to Mavericks it changed a lot:
    Lower performance.
    Transitions in the launchpad are laggy (and also buggy).
    Start up time increased.
    Anyway, that's why I want to make a clean install of Mavericks. Because I think that all these things happens because of making an upgrade rather than a fresh install (same thing occured with my iPhone and iOS 7, but that's another story )
    And my question is:
    Is it risky to format the Hard Drive and install the OS again? And do I need to do some things before doing it?(in order to keep the license and else)
    Assuming that I need just to format the hardrive and install the OS X, isn't it a "simple" of doing it? (like Cmd+R but making a clean install)
    Thanks!

    As you can see, there's a couple of things that are "bad" so instead of correcting every single problem (that would take me much longer) I just want to do a clean install and thats it.

    I suppose you could do that with Internet Recovery as well. You should not have an issue in terms of losing your OS license, as long as you use the same Apple ID that you have been using with your Mac.
    I didn't understand the license thing, but if I erase the disk and perform a clean install from a bootable USB that license won't lost am I right?
    I made a bootable USB of Mavericks just using this simple command:
    sudo /Applications/Install\ OS\ X\ Mavericks.app/Contents/Resources/createinstallmedia --volume /Volumes/SINTITULO --applicationpath /Applications/Install\ OS\ X\ Mavericks.app --nointeraction
    What do I need to do now? go to disk utility select erase, and then install using the USB?

  • After upgrade to Mavericks

    after upgrade to Mavericks , I have now two long black strip on my monitor 30 inches , one at the top, and the other one at the buttom,the rest of the display is fine with Mav. desktop screen with menu bar and dock. Before with mountain lion everything was fine. I have 2 display . one apple 20 inche display with no black strip and a 30 inches LG Flatron W3000H with those 2 black strip. I losing i inch tall at the top and same at the buttom.I try to install maverick again ,same problem, try the display panel of course , no luck. help 
           Mario

    I already try that , my largest resolution on the 30 inc is 2560 by1440.Not working.I mixed up , I actually upgrated from 10.6.8. When I boot from a 10.6.8 partition , I have no problem. But I realize that my 20 display can have 1680 by 1050 max and my 30 2560 by 1600 max. Then if I boot from 10.9 partition I am having the probem with the black strip and my 20 can max at 2560 by1600 and my 30 can max at 2560 by 1440 with the bars. I realize too that I do not have a menu bar on the 20 display, only on my 30. And when I do a safe mode boot 10.9 , the 2 bars are gone and I have a full 30 display.That workstation is a MacPro 2008 with ati HD 4870 512 k . I checked I did not found any updrate for the video cards.
       On my other workstion that I upgrated from Montain Lion to 10.9 which it the latest 27 inc IMac with a second 30 inc Apple display  I have no probem , no black bars and and I have a menu bar on both displays.By the way , before I bought the new Imac , I was working with the macpro with same video card and I had the two 30 inc display , running 10.6.8 with no problem.
      I have another problem too that I post on the wifi section. Since upgrade to 10.9 on the macpro , the one with the bars , I lost my wifi icon on the menu bar. i went to Network pane and I do no see a wifi section, only ethernet, firewire, and bluetooth and I try to add another choice the dialog do not let me choose from a wifi. I owne a airport extreme 4 gen and when i open airport utility the airport ext is discovered but no wireless.
    I work with pictures, with Lightroom 5 which I instal on the Imac 27, no problem. But I am waiting to install anything on the macpro in case I have to reinstall again 10.9 or if a 10.9.1 update could fix the problem.
    Anybody with these two problem, the bars and the missing wifi
      thanks      Mario

  • After upgrading to Maverick my apple wireless keyboard battery drain too quickly (30% in 1 day)

    Just as the topic's tittle, after upgrading to Maverick, along with many small errors, keyboard battery draining is by far the most not-so-pleasuring thing to deal with. My keyboard used to consume roughly a few battery percent per week. After the OS upgrade, still with the same using habit, it went from 80% down to 60% the last week, and from 60% to 30% just yesterday. Does anyone else here get this and any solution please? Much appreciate it! Thank you!

    Software bugs are killing not only IT industry (just look the drop in PC sales, and also a new sharp drop in tablet sales!), but industry in general.
    The reason for this is very simple: wrong people are on wrong jobs. As simple as that.
    To introduce this kind of bug, the drain of keyboard battery after installing an "advanced" version 100 (or so) operating system, and have this kind of bug a Jimmy from 3rd grade would not had made, is beyond comprehension.
    I trace these kind of stupidities for at least 30 years. While Microsoft can be forgiven as they started it all with a poorly conceived operating system foundation by a few teenegers and later it was impossible to go back to square one, the Apple on the other hand had all things available to them beautifully: the most advanced, architecturally, operating system foundation - Unix. And they failed too. They put an awkward GUI lipstick on that beautiful Unix operating system, with a lot, a LOT of bugs!?
    Again: the reason for all of this is that throughout the decades and decades, the wrong people were put on the wrong jobs. Nowadays VERY small percentage of educated people work on software systems development. There are no computer scientists, computer engineers, electrical engineers, software engineers anymore working for those companies like Apple. Throughout the decades of mis-management they had been replaced by all sorts of inadequate occupations: sociologists, psychologists, English majors, shoe salesmen, even Preachers .
    And the result we see: a never ending stream of stupidities like this one. If chimpanzees had spent all this time, all these intangible and tanglible investments, on creating operating systems I assure you they would do a MUCH better job than these dilletants

  • After upgrade to mavericks: time machine keeps asking for my back up disk and won't open unless i plug in the disk. any solutions?

    after upgrade to mavericks: time machine keeps asking for my back up disk and won't open unless i plug in the disk. any solutions?
    before the upgrade, i could open time machine without the need for having the back up disk plugged in.

    Ok. I got it to work, sort of....
    As I mentioned before I tried the "disk password" and the "Time capsule Password" options to see if I can start the back up again or start a new backup. Neither worked. So I tried the firmware down grade, but like you said that did not work. I then decided to try the "Account password" option and I have never used this option before becasue it states that if there is data on the drive it would not be acessable after creating an account. Since I wiped out the disk that was nno problem. When I created the new account and choose the drive it asked for the user name and password. I entered the info for the new account I just created(FYI this has nothing to do with your login username and password), bingo! It worked!
    Now I have two partitions on the TC disk. The old one and now the new account. I am guessing this is to be used if I have multiple computers, which I don't.
    I any case, I am going to wipe out everything again and try again to do a backup the way I had it before.

  • Animated gif in mail are not visible after upgrade to mavericks

    Hi,
    I use a animated gif in my signature in mail. This gif was playing normally (like a animated gif) in mountain lion when I writes a new message. After upgrading to mavericks I can't see the animated gif playing. I just see the first frame. However when I send a mail to my iPad using iOS 7 the animated gif is playing normally.
    Thanx for every answer!

    I'm having this issue as well — I can no longer send animated gifs in Mail with Mavericks (10.9.0). The image retains its full image size and remains a gif format, but does not play, just sits static. This also affects forwarding animated gifs — which play fine in the mail window — they are static in the compose window and are sent static.
