Changing out my HD for a new one on a new imac 2.4 20"

Hi all, I want to change out my stock 320 GB hitachi to something bigger. what is the biggest HD I can hold in the 20 inch iMac. I mean as long as it is a 3.5: SATA I should be OK. I am asking cause I saw there is a new Barracuda line(seagate) that is 7200.11 it has data rates like 105Mb/sec and like 32mb cache (I think ).

I'm using a 500GB 7200.11 in an external enclosure, and
it's FAST (faster than firewire) and quiet. However, you
might want to ask around to see if anyone has had success
with a 7200.11 product as an iMac internal drive. I found
a note on Seagate's web site warning that some drives are
incompatible with some earlier iMacs, but it's not clear
whether the warning applies to the 7200.11 family. Might
be a good idea to call Seagate's pre-sales tech support.

Every SATA Seagate I've seen (including my 7200.11) has
a jumper to force the drive into 1.5Gb/s mode -- but it's
unclear when/if the jumper should be installed. See the
following thread for some of the confusing details:

  • I want to upgrade my old airport express to the new express. Can I just switch out the old for the new or must I delete the old network first and start from scratch with the new express?

    I want to upgrade my old airport express to the new express. Can I just switch out the old for the new or must I delete the old network first and start from scratch with the new express?

    It is not necessary to delete your old wireless networks first, but doing so may eliminate confusion. If you wish to do that, open System Preferences > Network, and select Wi-Fi from the left column. Click the Advanced... button, then select your old wireless networks and delete them with the "–" (minus) button. Make sure the "Remember networks this computer has joined" remains checked.
    OK then Apply.
    This prevents your Mac from searching for your previous network which will no longer exist.
    A new Express creates an open wireless network that you must select before you can configure it. It appears in your Wi-Fi menu like this:
    Select it. AirPort Utility will load and walk you through its configuration.
    Edit: If you are really using OS X 10.5.1 as shown in your profile, the above screenshot is not applicable. Instead, select the network called "Apple network nnnnnn" and then launch AirPort Utility.

  • Preparing for a new iMac

    Hi,
    I currently have an iMac from 2008 (running Leopard) and will be buying a new iMac next month.  I'm not sure which iMac is the best option for me.  I know I want the 21.5 inch screen, but i'm not sure if I should get the base model and upgrade the ram, or stick with the 2nd level model with no upgrades (I don't want to go over $1500.00 before taxes.  My current model only has 1GB of memory, and i've never had an issue with it, so I'm thinking 16GB would be quite a significant difference - am I right?  If I go with the 2nd model, the processer would be better but still only has 8GB of ram.  My daily use of the computer is simply internet use, e-mail, iMovie, iDVD (which I know I won't have anymore), and iTunes.  I don't play games but I guess the most powerful thing I use is iMovie (capturing video as well). 
    Any Suggestions?  I'm not sure which model to go for. 
    Also,  I currently use Time Machine to back up my computer to an external harddrive.  I do not want my new computer to be a mirror image of the one I currently have.  I only want iTunes and iPhoto to stay the same.  How can this be done?  Is it possible to use the same external hard drive for back up of the new computer also?  I'd like to keep the old back up, and have a new one started for the new iMac.  Will Time Machine simply start a new backup and leave the old folder as is?  I'd like to keep it incase I ever want to get something from the old computer.
    Thanks in advance!

    8 GB of memory are enough for your uses, so you will have enough memory. Anyway, although Apple says that the Late 2012 21'5-inch iMac memory isn't replaceable, you can add more memory (it's difficult and you will void the warranty, but you can add memory) > http://eshop.macsales.com/shop/memory/iMac/2012_21.5/DDR3L
    When you want to restore a Time Machine backup, the Mac will ask you what you want to restore, so select only the folders you want to restore. For example, the iTunes library is stored in Music folder, so tick your Music folder, and iPhoto library is stored in Pictures folder, so tick the Pictures folder. You can unmark the rest of the folders.
    Note that you will be running a new operating system, so Time Machine will have to make a full backup of your Mac with all changes from Leopard to OS X Mountain Lion (near everything of Mac OS X)

  • How do I make a boot disk for my new iMac?

    How do I make a boot disk for my new iMac?

    Make Your Own Mavericks, Mountain/Lion Installer
    After downloading the installer you must first save the Install Mac OS X application. After the installer downloads DO NOT click on the Install button. Go to your Applications folder and make a copy of the installer. Move the copy into your Downloads folder. Now you can click on the Install button. You must do this because the installer deletes itself automatically when it finishes installing.
       2. Get a USB flash drive that is at least 8 GBs. Prep this flash drive as follows:
    Open Disk Utility in your Utilities folder.
    After DU loads select your flash drive (this is the entry with the mfgr.'s ID and size) from the leftside list. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID then click on the OK button. Click on the Partition button and wait until the process has completed.
    Select the volume you just created (this is the sub-entry under the drive entry) from the left side list.
    Click on the Erase tab in the DU main window.
    Set the format type to Mac OS Extended (Journaled.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
    Click on the Erase button. The format process can take up to an hour depending upon the flash drive size.
    Use DiskMaker X to put your installer clone onto the USB flash drive.
    Make your own Mavericks flash drive installer using the Mavericks tool:
    You can also create a Mavericks flash drive installer via the Terminal. Mavericks has its own built-in installer maker you use via the Terminal:
    You will need a freshly partitioned and formatted USB flash drive with at least 8GBs. Leave the name of the flash drive at the system default, "Untitled." Do not change this name. Open the Terminal in the Utilities folder. Copy this entire command line after the prompt in the Terminal's window:
         sudo /Applications/Install\ OS\ X\ Mavericks.app/Contents/Resources/createinstallmedia --volume
         /Volumes/Untitled --applicationpath /Applications/Install\ OS\ X\ Mavericks.app --nointeraction
    Press RETURN. Enter your admin password when prompted. It will not be echoed to the screen so be careful to enter it correctly. Press RETURN, again. Wait for the process to complete which will take quite some time.

    I am looking for a Suitable ethernet cable for my new Imac 27-inch iMac 3.4GHz quad-core Intel Core i5 (Mavericks 10.9.4) & old imac 1 GHZ PowerPC G4 (10.4.11) for transfering files, documents, photos into my new intel mac from my old power PC imac.
    Can anyone please advise me which suitable ethernet cable would be suitable for tasks.
    Many thanks

    Note, the iMac G4 1 Ghz only supports 10/100 base-T.  Firewire is up to 4 faster with a cable such as this one:

    And since you are migrating from a G4, be sure to make your files portable to newer data formats before transferring.  Old Appleworks/Clarisworks files are not compatible:

  • How to obtain idvd for my new iMac

    How do i obtain idvd for my new imac?

    obtain idvd for my new imac?
    If you are still within your 15 day return period.  Call Apple they will sent out iDVD at no charge.  (There are no realistic substitutes.)
    Nicely explain that you may return the computer without iDVD. That usually does the trick.  You MUST speak to a senior advisor to get a free copy. The first tier people cannot do it.
    408-996-1010
    800-692-7753
    If that doesn't work you can purchase iLife 11  (includes iDVD) on disk.
    IDVD is a wonderful piece of software and well worth the low cost of $40.

    Hi ..
    No, there isn't but you might want to take a look at refurbished iMacs >  Refurbished Mac Computers - Refurbished Notebooks & Desktop Computers - Apple Store (U.S.)
    Refurbished products come with the same one year limited warranty as does a new product.

    A PC can have more issues connecting than a Mac.
    But it really should not matter.. so just try it in situ.. press and hold the reset.. once it starts up, it will return to default IP, 10.0.1.1 the PC should then be able to find it via the airport utility.
    If not drag it over to the Mac and plug in there by ethernet.. or since it is a laptop, really should not be that difficult to drag the Laptop and plug it into the TC.
    Important thing is to get access to the TC.
    The Mac if it is running lion, then you MUST download and install 5.6 airport utility to do anything useful.

  • How can i use my old iMac as a extended desktop display for my new iMac?

    I recently purchased a 21.5 in iMac and wanted to use my old iMac as a extended desktop. My new iMac has thunderbolt and USB 3.0 connections while my old iMac has firewire (400 and 800), USB 2.0 and mini-DVI. Is this posible?

    Welcome to Apple Support Communities
    If your iMac has got Mini-DVI, you have a 17, 20 or 24-inch iMac that doesn't support Target Display. Late 2009 and Mid 2010 27-inch iMacs, and iMacs with Thunderbolt can be used as external displays. Read > http://support.apple.com/kb/PH11302?viewlocale=en_US&locale=en_US
    If your old iMac doesn't support Target Display mode, you can use ScreenRecycler to use your old iMac as an extended display for the new iMac. The only thing you need is that both Macs are connected to the same network

    Dear Mr. Z,
    Thank you for contacting APC.
    The compatibility of the UPS with an OS is dependant on the installed management software the UPS communicates with.
    1. BR900GI - PowerChute Personal - no compatibility with OSX, please find the compatibility chart below:
    http://www.apcmedia.com/salestools/JNOE-7GSAQJ/JNOE-7GSAQJ_R11_EN.pdf

    http://www.apcmedia.com/salestools/ASTE-6Z5QEV/ASTE-6Z5QEV_R37_EN.pdf
    Alternately, if you install a network management card (AP9630 or AP9631) in the SUA750I, it will be able to communciate with the PowerChute Network Shutdown software. This is compatible with Mac OS X Server 10.7.2 x64:

    The key to what you seem to want to do is to be able to get Apple's Time Capsule router to "join" the network that your Conceptronic router.  I believe that works with some third-party routers, but I've never seen a list of those that work in such a configuration and I have no experience with Conceptronic equipment.
    You might be better off with a Network-Attached Storage (NAS) device instead of a Time Capsule.
