"OS X Mavericks requires at least 2 GB of memory"

I have an early 2008 iMac running Snow Leopard, version 10.6.8. When I try to install Mavericks, it says "We could not complete your purchase. OS X Mavericks requires at least 2 GB of memory." When I click "About this Mac", it says we have 1 GB of memory. But when I go into the HD drive, it says we have 181.6 GB of memory. How can we get this to work?

You can install as much as 6 GB in your early 2008 iMac.
Other than Apple there are only two vendors with which I have personal experience and can recommend: Crucial and OWC. People have reported problems with many other brands, yet Crucial and OWC's prices are as good as any you are likely to find. Patriot is another brand recommended by ASC contributors but I have no experience with them.
Go to Crucial and download the little app that examines your system and recommends RAM upgrade options.
Their prices are good but don't have to buy memory from them - determine what you need and buy it from Crucial or OWC / MacSales.

  • App store says OS X 10.8 requires at least 2 GB of memory. I have 249GB of memory

    I have just copied my entire HD to an external drive and then wiped the original HD as it was running really slowly and want to rebuild with only the necessary programmes etc. First thing I want to do is upgrade from Snow Leopard (OS X 10.6.8) to Mountain Lion. When i try to download from the app store I get this message: OS X 10.8 requires at least 2 GB of memory. Having just wiped my HD I have the full capacity of memory (250GB). Can anyone help?
    FYI - I have just managed to do the exact same upgrade from Snow Leopard to Mountain Lion on my Mac Book Air with no problems at all.
    iMac details below:
    Model Name: iMac
    Model Identifier: iMac7,1
    Processor Name: Intel Core 2 Duo
    Processor Speed: 2 GHz
    Number Of Processors: 1
    Total Number Of Cores: 2
    L2 Cache: 4 MB
    Memory: 1 GB
    Bus Speed: 800 MHz
    Boot ROM Version: IM71.007A.B03
    SMC Version (system): 1.20f4

    Your confusing hard drive storage space with RAM (Random Access Memory) memory.
    The two are completely different.
    You only have 1 GB of RAM installed.
    Your iMac can take up to a max. of 6 GBs of RAM.
    I suggest installing the max. amount.
    You can purchase reliable Mac RAM from online RAM vendors Crucial memory or OWC (macsales).
    They have a chart or table that will tell you the type and specs of the RAM you need for your iMac.
    Good Luck!

  • When I try to download OS X Lion my Macbook says that I need at least 2 GB of memory even though I already have it

    My MacBook says I have 17.41 GB available but the Mac App Store will not let me dowload OS X Lion. It says "We could not complete your purchase. Mac OS X 10.7 requires at least 2 GB of memory."
    What does this mean? This is confusing me.

    The warning is in regard to RAM memory not space on your hard drive. Your computer needs 2 GBs of RAM for Lion. You will need to upgrade your RAM to at least 2 GBs in order to use Lion. I suggest more if the computer can accommodate more than 2 GBs.

  • When i try to download mavericks i can't . it said that i need at least 2 Go of memory but i have a lot. What to do?

    Also, if you really do not know or sure of what you are doing,
    Before embarking on a major OS upgrade, it would be wise, advisable and very prudent if you backup your current system to an external connected and Mac formatted Flash drive OR externally connected USB, Thunderbolt or FireWire 800, Mac formatted hard drive. Then, use either OS X Time Machine app to backup your entire system to the external drive OR purchase, download, install and use a data cloning app, like CarbonCopyCloner or SuperDuper to make an exact and bootable copy (clone) of your entire Mac's internal hard drive.
    This step is really needed in case something goes wrong with the install of the new OS or you simply do not like the new OS, you have a very easy to return your Mac to its former working state.
    Then, determine if your Mac meets ALL minimum system install requirements.
    To install Mavericks, you need one of these Macs:
    iMac (Mid-2007 or later)
    MacBook (13-inch Aluminum, Late 2008), (13-inch, Early 2009 or later)
    MacBook Pro (13-inch, Mid-2009 or later),
    MacBook Pro (15-inch or 17-inch, Mid/Late 2007 or later)
    MacBook Air (Late 2008 or later)
    Mac mini (Early 2009 or later)
    Mac Pro (Early 2008 or later)
    Xserve (Early 2009)
    Your Mac also needs:
    OS X Mountain Lion, Lion, or Snow Leopard v10.6.8 already installed
    2 GB or more of memory
    8 GB or more of available space
    Next,
    If you run any older Mac software from the earlier PowerPC Macs, then none of this software will work with the newer OS X versions (10.7 and onward). OS X Snow Leopard had a magical and invisible PowerPC emulation application, called Rosetta, that worked seamlessly in the background that still allowed older PowerPC coded software to still operate in a Intel CPU Mac.
    The use of Rosetta ended with OS X Snow Leopard as the Rosetta application was licensed to Apple, from a software company called Transitive, which got bought out, I believe, by IBM and Appe  could no longer secure their rights to continue to use Rosetta in later versions of OS X.
    So, you would need to check to see if you have software on your Mac that maybe older than, say, 2006 or older.
    Also, check for app compatibilty  here.

    If you have any commercial antivirus installed and/or hard drive cleaning apps installed on your Mac, like MacKeeper, CleanMyMac, TuneUoMyMac, MacCleanse, etc. now would be a good time to completely uninstall this apps by doing a Google search to learn how to properly uninstall these types of apps.
    These types of apps will only cause your Mac issues later after the install of the new OS X version and you will have to completely uninstall these types of apps later.
    Once you have determined all of this, you should be able to find the latest version of Mavericks by clicking on the Mac App Store icon in the OS X Dock and then login to the Mac App Store using your Apple ID and password.
    You can then begin the download and installation process of installing OS X 10.9 Mavericks from the Mac App Store.

  • I have 9.0 GB available on iCloud. Why am I getting a message saying I can't install to iOS7.1.1 on my iPhoneb/c it requires at least 1GB of storage?

    I have 9.0 GB available on iCloud. Why am I unable to install iOS7.1.1 on iPhone? Gray area says it requires at least 1.9 GB of storage!

    iCloud storage is for backups. You need at least 1.9 gigs of local storage, that is storage on your phone itself. Go to Setting>General>Usage to see what's taking up space and what you can remove.
    Best of luck.

  • HT201364 OS X Mavericks required space 8 GB.  Does this mean 8GB of free Hard Disk Space?

    It does. But you need a whole lot more free disk space than that. Having 8 GB of RAM wouldn't be a bad idea either.

  • Iam trying to buy OS Lion to my Imac but i can not buy  because its saying Mac OSX 10.7 requires at least 2 GB of memomie and mine has 1 GB what can i do?

    iam trying to buy OS Lion to my Imac but i can not buy  because its saying Mac OSX 10.7 requires at least 2 GB of memomie and mine has 1 GB what can i do?

    If it's just a question of memory, you can buy and install more. It could also be that your iMac is just not compatile with Lion.
    Minimum requirements for Lion are:
    Mac computer with an Intel Core 2 Duo, Core i3, Core i5, Core i7, or Xeon processor
    2GB of memory
    OS X v10.6.6 or later (v10.6.8 recommended)
    7GB of available space

  • IdeaPad 10Se and running software requiring at least 800 x 600 grafic resolution

    I have bought an IideaPad 10Se this week with the 1024 x 576 resolution. I have problems installing harwere requiring at least 800 x 600 resolution. I installed my HP writer that requires at least 800 x 600 by attaching an external screen and made only displayed on this screen during installation. That was a fine work-around for installations. Now I have installed a Canoscan 4200f scanner using the same work-arround. Unfortunately the Canoscan Toolbox programme tests the resolution everytime it starts and when it is not up to 600 in vertical resolution it refuse to start. Is there a way to fool programmes that the resolution is 600 in vertical resolution and not just 576? Or how can I solve this problem.

    I had a problem installing the Cisco VPN which required at least the 800x600 resolution
    to install but not to actually run the software after it was installed.
    It seems you can set the resolution to 640x480 using third party software but not
    any resolution with more than 576.
    FWIW 1024x576 is exactly the 16:9 aspect ration as found in HD TVs.
    There is software that won't install and there is software that won't run after it is installed.
    I found if I plugged my spare monitor into the VGA port and then used the FN+F3
    you can make the external monitor your primary one temporarily. This assumes
    the external monitor supports at least 800x600 of course.
    Then just install or run your software 800x600 normally.
    It's a kludge for the "won't install but will run" type software.

    Upgrading from Snow Leopard to Lion or Mountain Lion
    You can upgrade to Mountain Lion from Lion or directly from Snow Leopard. Mountain Lion can be downloaded from the Mac App Store for $19.99.
    If you sign into the App Store and try to purchase Mountain Lion but the App Store says your computer is not compatible then you may still be able to upgrade to Lion per the following information.
    A. Upgrading to Mountain Lion or Mavericks
    To upgrade to Mountain Lion or Mavericks you must have Snow Leopard 10.6.8 or Lion installed. Purchase and download Mountain Lion or Mavericks (Free) from the App Store. Sign in using your Apple ID. Mountain Lion is $19.99 plus tax. The file is quite large, over 5 GBs, so allow some time to download. It would be preferable to use Ethernet because it is nearly four times faster than wireless.

    B. Upgrading to Lion
    If your computer does not meet the requirements to install Mountain Lion, it may still meet the requirements to install Lion.
    You can purchase Lion by contacting Customer Service: Contacting Apple for support and service - this includes international calling numbers. The cost is $19.99 (as it was before) plus tax.  It's a download. You will get an email containing a redemption code that you then use at the Mac App Store to download Lion. Save a copy of that installer to your Downloads folder because the installer deletes itself at the end of the installation.

  • Build - Generates an "NTSC DVD requires at least one AC3 or PCM Audio track"

    I'm using the trial version to make my first DVD with Encore. All went fairly smoothly until I went to "build" the DVD and received the "NTSC DVD requires at least one AC3 or PCM Audio track..." message. I continued with the build and tested the DVD. All the audio was fine except for audio assigned to my menus via the audio section, assigned from the motion tab, was not heard on the DVD. The Menu audio did however sound good from the preview mode. The audio that I tried to use in the motion audio field, was from a M2P file from the same clip that worked fine on the DVD. The video field was not set to anything on the motion menu.
    My questions are: 1) How do I clear the error? 2) How do I get the Audio on my menus?
    (Not sure if this item belonged in the forum, the error forum, or the audio forum - Sorry).
    I don't even know for a fact that the error message was tied directly to the menu. I'm sure its something basic that I just missed - Thanks.
    Eric

    Thanks you very much, now I will be able to sleep tonight. My editing system (Edius) had both the ability to export my sound track to PCM AIFF & PCM WAVE, which worked great for the sound on the menus, as well as an elementary stream (M2V) format which worked good for the main sound track. I looked in the Audio Forum to find out about the elementary streams. The end result is that my DVD build error cleared as well as getting audio on the menu.
    Once again, thank you both for your help.

  • DNS error - "requires at least one Nameserver"

    Hi,
    I have a working Snow Leopard  10.6.8 server - working in all respects except DNS.
    I decided to take the advice of posters on this site and turn off dns and re-enter it from scratch.
    I was able to delete all of the settings on the Zones tab, EXCEPT for the primary zone.
    When I delete it it just re-appears by itself !
    I then try to enter the data that is correct for the name server by clicking the + button under Nameservers.
    When I enter the correct data and click OK, it says "Some configuration data is invalid: The zone..... requires at least one Nameserver" !
    Well... I'm trying to enter exactly that!
    Anyone have any clues how to fix this?

    I saw similar behavior recently on one server I was working on.   (This was with the 10.6.7 and associated server tools; haven't been down this path with 10.6.8 and the updated server tools.)
    If what I saw is similar to what you're seeing here, then try this...
    First, if you don't have a recent backup copy of your boot disk that you trust and are willing to use, then back up your boot disk before you proceed by booting a distribution disk and using Disk Utility to make a full copy of your boot disk to external storage.   This backup is your path back to operations if Badness Happens.
    Once you have rebooted your system from your backup, stop DNS services and exit Server Admin, if either or both are running.
    Then launch Terminal.app, and navigate into and delete or rename the Server Admin properties list file:
    ~/Library/Preferences/com.apple.ServerAdmin.plist
    Then relaunch Server Admin, and you should be able to fix your DNS services.
    This is your local copy of the preferences file for Server Admin, not a system-wide preferences.
    The "immutable" DNS settings were (after digging around) being recovered from the plist file.  (I've also had rare occasion to edit that plist file, when things go Really Wonky, and to change the immutable settings to some other temporary domain name, which then let me Get On With It All with the intended domain name.)

  • HT201263 Unable to update IPhone, I get the message "this update requires at least 2.4 GB of available storage"

    I'm unable to update IPhone. I get the message, "this update requires at least 2.4 GB of available storage". What should I do?

    The error message is talking about storage space in your iPhone not on iCloud which is what you bought.
    You are going to have to clean up space on your iPhone by removing files from it. Good candidate for removal are music and photos.
