HT201364 To install Mavericks, you need at least 2 GB of memory and I only have 1 GB. Can I load more memory?

Can I load more memory and where do I purchase it?

Yes, you can, though you'd need to tell us your exact model of iMac before we could tell you specifically what memory you will need and how much you can expand to. There are a number of good vendors; I've used Crucial and Other World Computing (OWC). Both have been of high quality and good service, and either can tell you exactly what you'll need for your iMac. Other folks here may have additional vendor recommendations.
I'd definitely recommend expanding beyond 2GB. It won't cost that much more and your performance is almost sure to be better than if you just get the minimum 2GB.
Regards.

  • I bought my 20" iMac in Nov of 2007 and when I try to purchase the upgrade for lion I'm told I need 2GB of memory and I only have 1GB.  How can I get more?  I am currently running snow leopard

    Trying to upgrade to Lion on my 20" iMac that I bought in Nov. 2007.  Currently I'm running on MAC OS X version 10.6.8.  When I tried to buy the upgrade I got a response that Lion requires 2 GB of memory and I only have 1 GB.  How can I get more memory and will my computer be compatible with Lion when I do get more memory?

    Yes you can install more RAM. Up to 6 GBs. Two - 200-pin PC2-5300 (667MHz) DDR2 SO-DIMMs. For the maximum use one 4 GB and one 2 GB. Otherwise install a pair of 2 GB modules for a total of 4 GBs.
    You can purchase suitable RAM at DataMem or OWC. OWC also has video tutorials on installation.

  • Install what you need, don't add frivolous drivers, fonts, plugins, widgets

    As a troubleshooter, I've always been amazed at the number of files people stash on their desktop, number of installed applications, number of installed plugins, etc... Some people try to fill their hard drives to an extreme. The lesson learned here, which I hope to pass on to anyone reading this tip, keep it simple. Only install what you need, and nothing more. Archive away anything you wish to keep for posterity, but don't just let it hang out unless you might need it right away. Backup your data religiously, and remember to keep at least two copies of your data, and preferably at least one off site.
    For every added driver, font, plugin, and widget you might find one that doesn't work well with another, or one that may not have been tested with your operating system. If you don't ensure they are known to work well together, you are building what is idiomatically called a "house of cards" or "jalopy."
    And the more you add, the more that can go wrong. The more you add, the longer you'll spend the time of you or your troubleshooter solving problems. And remember, time itself is money. So be careful, and only add what you need to your system. Practice good judgement. If unsure if something extra is necessary, ask on the board.

    It occurs in the \usr\sap\jupgrade\log\CHECKS.LOG file, when I run the 'General Checks' stage of the' PREPARE Module Status' program.
    I am trying to patch a SAP 7.01 SAP Portal to EHP2. The server is running Windows 2003 SP2, MS SQL Server 2008 SP1. I believe that the versions of both the OS and DB are sufficient for EHP2. The upgrade will use a 7.2 kernel and I think that the software versions are sufficient for that too.

    I have tried to continue by selecting:
    Reselect PREPARE modules to be executed again
    and chose Finalization. Then Continue.
    But it says:
    Module selection is invalid Unable to execute module 'Finalization'. Module 'Finalization' can run only after module 'General checks' has run successfully
    Then I ran the General checks module again, but it failed again with the same error.
    Please can you suggest how I can proceed?
    Thanks.

  • Get an error message when importing from iPhoto says, "There is not enough free space on your Aperture Library volume to import the selected items. It is estimated that you need at least 44GB of free space."

    I get an error message when importing from iPhoto that says, "There is not enough free space on your Aperture Library volume to import the selected items. It is estimated that you need at least 44GB of free space." the drive is empty, I just reformatted it to Mac OSX journaled.

    I'm guessing this is an extrenal drive, correct? If so make sure the library you're importimng into is really located on the external drive. By default Aperture creates its library in your home pictures folder.

  • Am running Tiger 10.4.11; just got Snow Leopard 10.6.3 (regular OS disk, not an upgrade); when I install Snow Leopard, will it wipe everything?  overwrite Tiger?  Do I need to make backups of applications and files to reinstall after Sno Lprd loads? thx!

    Am running  Tiger 10.4.11; just got Snow Leopard 10.6.3 (regular OS disk, not upgrade).  When I install Snow Leopard, will it wipe everything?  overwrite Tiger?  Do I need to make backups of applications and files to reinstall after Snow Leopard Loads?  thanks!

    Hi Donald,
    No it doesn't erase anything by default, it does what we used to call an  Archive and Install feature, which can give you a new OS, yet preserve your files and settings if you have enough room on your HD...
    http://docs.info.apple.com/article.html?artnum=107120
    But it does it automatically unless you specifically erase the Disk, but will replace Tiger completely for the OS & several Apple Apps like Safari, Mail, etc, yet preserve your old settings for those!
    If you think you may need Tiger to run any APPs that do not work in SL/10.6, then clone or backup first.
    I would recomend 2 things before installing though...
    Make sure you have enough RAM & HD space.
    Snow Leopard/10.6.x Requirements...
    General requirements
       * Mac computer with an Intel processor
        * 1GB of memory (I say 2GB at least)
        * 5GB of available disk space (I say 30GB at least)
    If it's a core Duo & not a Core2Duo, then it'll only run in 32 bit mode.
    "Try Disk Utility
    1. Insert the new Mac OS X SL/10.6 Install Disc, then restart the computer while holding the C key.
    2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.)
    Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.
    3. Click the First Aid tab.
    4. Select your Mac OS X volume.
    5. Click Repair. Disk Utility checks and repairs the disk."

    Hi,
    What version of the OS did you upgrade from ?
    Anything before OS X 10.8.2 may have an issue if the Logic/Mother board has been replaced and the Serial Number not "flashed" back to it.
    In the Apple Icon menu use the About this Mac item.
    In the new panel click twice on the line that tells you the current OS level
    It will change to the Build number (and alternative count to the OS versions) and then the Serial Number.
    If it is missing you need to get it replaced.
    (It is supposed to be done on Repair or Refurbishment).
    An Apple Store or Apple Authorised Service Provider as the best choices.
    There are apps you can download (They are Mac Model specific) but needs careful typing as it is a once only trip.

  • I am trying to download OS X Lion from the app store and it says it can not complete my purchase becuase it needs at least 2GB of space and i have that

    i am trying to download OS X Lion from the app store and it says it can not complete my purchase becuase it needs at least 2GB of space and over 2GB on my computer...any ideas??

    That requirement is referring to the need for 2gB of RAM, not hard drive space.

    I only have one video project that I ever published to iDisk. It didn't have any music or photo files attatched to it, just a few clips stitched together. I can play these clips right now in the Event Library (so I know the source files are on my computer), but strangely, under the Project Library, the project is not there. I'm almost certain that I didn't store the project on iDisk; I just completed the video and published it to iDisk (as a .mov file I think) for family to see. I've tried to figure out how to get iDisk to stop looking for this project to no avail.
    I don't know if others have experienced this, but if I click on any project and on the menu bar select Share --> Remove From --> Media Browser... it lists iPod, iPhone, iPad, tv, Computer and MobileMe. Why would MobileMe be an option here? This is the case for any video project I select. Didn't iLife '11 and/or OSX 10.8 remove all mention of MobileMe? I wonder if this is part of the problem too.
    Edit: I just removed every project I have from the Media Browser. Still no luck.

    Why do you need the serial number? The phone can't be tracked by either serial number or IMEI.

  • Hi.  I have a Macbook Pro Model 5,5 with one 800 firewire port.  I need to create two firewire 800 ports but only have an SD card slot (this is for video interface with 2 cameras).  Is this possible or do I have to have an express card slot in order to do

    Hi.  I have a Macbook Pro Model 5,5 with one 800 firewire port.  I need to create two firewire 800 ports but only have an SD card slot (this is for video interface with 2 cameras).  Is this possible or do I have to have an express card slot in order to do this?

    Hi Jessica,
    No, the SD slot will not work, you need an ExpressCard/34 slot.
    I do not know if it works with cameras, but with two or more HDs, if the first one has two FW ports, you can "daisy chain" one or more additional HDs from it.

  • HT204150 Hi, I made a mistake by allowing facebook to download all my contacts in my address book. Now i need to clean my address book and keep only my original contacts. If i do it on my macbook, will it reflect on my iphone?

    Hi, I made a mistake by allowing facebook to download all my contacts in my address book. Now i need to clean my address book and keep only my original contacts. If i do it on my macbook, will it reflect on my iphone? Or will my iphone redownload all the contacts i deleted when i connect it to my macbook or through the cloud?
    when working with icloud, is there a primary device (macbok, ipad...) on which if the changes are made, they reflect on all other devices?

    I see.  If you are syncing contacts with iCloud on both your Mac and your iPhone, deleting a contact from either device will delete them from icloud.com and all other devices. 
    What's really going on with iCloud is that your contacts actually reside on the iCloud server.  Your Mac and iPhone are merely reading the current contact list as it exists on the server.  When you delete a contact (or make any other change) on either device, you are making these changes on the server.  As a result, all other devices "syncing" contacts with the same iCloud account will read this change.  When you log onto icloud.com, you are viewing the server from your browser.
