I want to upgrade the logic boars and CPU in my Mac Pro 1,1

Is this possible?
I'm doing it in order to be able to get the 64-bit EFI and upgrade to ML.
Does anyone have any experience with this?

It is far more complex than any mere mortal wants to undertake. Many issues around the internal airflow and temeprature mean it is far from easy.
You should buy a used 2009 or later or a refurbished (good as new) Apple model instead. The memory on 2009 and later is so much cheaper you can justify the purchase in what you will save in memory cost.
If you are a developer, there is a rather complex way you can run EFI-64 in RAM. But it is not simple enough or trouble-free enough for regular Users.

  • I have the original iPad and want to upgrade the operating system and do not have a home computer available to go through iTunes to upgrade it. Is there a place that I can take it to upgrade it for me?

    I have the ipad1 and want to upgrade the IOS system and do not have a home computer to do it. Is there someplace I can take it and have it done for me professionally? I checked with Best Buy and they declined.

    A physical Apple Store. If you want to do it yourself, you can use any computer with an Internet connection.

  • I have a mac mini mid 2011, this device have; 2,3GHz and 2 Gb Memmory.I want to upgrade the memory and i need the list of supported memory modules

    i have a mac mini mid 2011, this device have; 2,3GHz and 2 Gb Memmory.I want to upgrade the memory and i need the list of supported memory modules. i am from turkey.

    Welcome to Apple Support Communities
    The Mid 2011 Mac mini supports 8 GB of memory officially, but you can install up to 16 GB of RAM, so you can use 2, 4 and 8 GB modules. You can buy more RAM from OWC or Crucial.
    If you are looking for memory at a local shop, make sure you buy 1333 MHz DDR3 memory. See > http://support.apple.com/kb/HT4432?viewlocale=en_US&locale=en_US

  • I am on an iMac6,1 and on OS 10.5.8 and I want to upgrade the OS. Can I load Lion on my machine, and how do I go about doing it.. I have everything backed up.

    I am on an iMac6,1 and on OS 10.5.8 and I want to upgrade the OS. Can I load Lion on my machine, and how do I go about doing it.. I have everything backed up.

    Start by checking if you can run Snow Leopard:
    Requirements for OS X 10.6 'Snow Leopard'
    http://support.apple.com/kb/SP575
    OS 10.6 Snow Leopard is once again available for $19.99 from the Apple Store:
    http://store.apple.com/us/product/MC573/mac-os-x-106-snow-leopard
    and in the UK:
    http://store.apple.com/uk/product/MC573/mac-os-x-106-snow-leopard
    but nobody knows for how long it will be available.
    When you have installed it, run Software Update to download and install the latest updates for Snow Leopard.
    To use iCloud you have to upgrade at least to Lion, but some functions are only available in Mountain Lion:
    http://support.apple.com/kb/HT4759
    You can also purchase the code to use to download Lion (Lion requires an Intel-based Mac with a Core 2 Duo, i3, i5, i7 or Xeon processor and 2GB of RAM, running the latest version of Snow Leopard), or you can purchase Mountain Lion from the App Store - if you can run that:

  • I have a rather old iMac 20" (mid 2007) and I want to upgrade the Hard drive. How do I change it? How do I transfer all my applications? May I just copy the old hd into the new one? Thanks.

    I have a rather old iMac 20" (mid 2007) and I want to upgrade the Hard drive. How do I change it? How do I transfer all my applications? May I just copy the old hd into the new one? Thanks.

    There are many online tutorials on how to change out the HD on a mid 2007 iMac. One of the originals is from 2007 and is Upgrade your iMac 20" or iMac 24" aluminum (mid 2007) to 1TB Hard Drive and 4 GB RAM - DIY Guide. As far as migrating your system Apple helps out with that in Setup Assistant which automatically starts when you turn on a new Mac for the first time. After you have installed the new HD you will have to format the new HD to Mac OS Extended (Journaled) and then you will have to install OS X. The first time you turn it on Setup Assistant will start. Follow the directions and you will be fine. In order to restore your information you will need to backup what is on the current internal HD first. I'd recommend using Time Machine (Assuming you are using Leopard or later) AND also creating a bootable clone using either SuperDuper or Carbon Copy Cloner.
    Please complete your profile so at the very least we know what version of OS X your machine has installed.

  • I have a 15' Macbook Pro, mid 2010 running Mavericks. I want to upgrade the hardware by increasing the RAM to 8GB and replacing the HD for a SDD one. What would be the best way to install mavericks on the new HD? I have the original OS X CD.

    I have a 15' Macbook Pro, mid 2010 running Mavericks. I want to upgrade the hardware by increasing the RAM to 8GB and replacing the HD for a SDD one. What would be the best way to install mavericks on the new HD? I have the original OS X CD.
    From what I read, I have 2 choices: 1. to install OSX and then upgrade to Mavericks, but I'm not sure if this would be possible (to upgrade directly from OSX to Mavericks); and 2. to use a software called Super Duper.
    I wouldn't like to have to use a third party software to do this, so the question is: is there a better way to install directly the Mavericks not having to use a third party software?

    Install the new drive in the computer.
    Install the old drive in an external USB or Firewire enclosure.
    Boot the computer from the Recovery HD on the external drive.
    Use Disk Utility to partition and format the new internal drive.
    Clone your external drive to the internal drive.
    How to replace or upgrade a drive in a laptop
    Step One: Repair the Hard Drive and Permissions
    Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Installer menu (Utilities menu for Tiger, Leopard or Snow Leopard.) After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
    If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
    Step Two: Remove the old drive and install the new drive.  Place the old drive in an external USB enclosure.  You can buy one at OWC who is also a good vendor for drives.
    Step Three: Boot from the Recovery HD on the external drive.  Restart the computer and after the chime press and hold down the OPTION key until the boot manager appears.  Select the icon for the Recovery HD then click on the downward pointing arrow button.
    Step Four: New Hard Drive Preparation
      1. Open Disk Utility from the main menu and click on the Continue button.
      2. After DU loads select your new hard drive (this is the entry with the
          mfgr.'s ID and size) from the left side list. Note the SMART status of
          the drive in DU's status area.  If it does not say "Verified" then the drive
          is failing or has failed and will need replacing.  Otherwise, click on the
          Partition tab in the DU main window.
      3. 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.
      4. 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.
      5. 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.
      6. Click on the Erase button. The format process can take up to several
          hours depending upon the drive size.
    Step Five: Clone the old drive to the new drive
      1. Using Disk Utility still opened.
      2. Select the destination volume from the left side list.
      3. Click on the Restore tab in the DU main window.
      4. Check the box labeled Erase destination.
      5. Select the destination volume from the left side list and drag it to the
          Destination entry field.
      6. Select the source volume from the left side list and drag it to the
          Source entry field.
      7. Double-check you got it right, then click on the Restore button.
    Destination means the new internal drive. Source means the old external drive.
    Step Six: Open the Startup Disk preferences and select the new internal volume.  Click on the Restart button.  You should boot from the new drive.  Eject the external drive and disconnect it from the computer.

  • I have an older Airport Extreme (disc shaped) that we use with my wife's PowerBook (OS 10.5.8) and my MacBook Pro (OS 10.9.4).  We currently only have Airport Utility on her Mac, but I want to upgrade the utility so I can use it on mine.

    I have an older Airport Extreme (disc shaped) that we use with my wife's PowerBook (OS 10.5.8) and my MacBook Pro (OS 10.9.4).  We currently only have Airport Utility on her Mac, but I want to upgrade the utility so I can use it on mine. Which version of the utility will work on my MacBook, and still control the older Airport Extreme?

    if I update the Airport to the latest version, and "control" it with my MacBook Pro, will the older G4 still be able to use the signal from the new Airport?
    Yes. Your G4 shouldn't have any difficulty connecting to a Wi-Fi network provided by the latest 802.11ac AirPorts as they support the earlier radio modes that the G4 uses.

  • I want to upgrade the IOS of my Cisco 2821 from Version 12.4(11) to v 15.1 (XB), but I have CCME v 4.2 (0), is there any problem if I only upgrade the IOS and leave the CCME as it ?

    Thanks

    CME is part of the IOS, so you can't upgrade the IOS seperately from CME.
    That said, if this is a production environment you should proceed with caution and be prepared to roll back as you may find bugs, etc.
    You should also look at release notes and make sure your phone firmware will still work or needs to be upgraded too.

    i have an iphone 4 with 4.3.2 version, i want to upgrade the software. but my phone is not getting synchronised on itunes and not getting detected. also there is no update software tab under settings.please help me

    If your phone isn't being recognized by your computer, you need to follow the steps in this article to resolve that
    Also, some basic isolation needs to be done. Does it show up in itunes on any other computers? do you have other cords you can test with to see if it might be the cord? if the phone doesn't show up on any computers, it's likely your phone has a hardware issue

    Then you either have a network problem or a hardware problem or a corrupted hard drive. You might try:

    You can also try downloading from another computer on a different network connection.

    Welcome to Apple Support Communities
    Of course. Corsair RAM is compatible with your Mac and the Early 2011 MacBook Pro supports 16 GB of memory. Make sure you buy the correct memory for your MacBook Pro. See > http://www.corsair.com/us/memory-by-product-family/mac-memory-upgrades.html

  • HT2305 I want to upgrade IMovie, IPhoto, Garageband and ITunes. My MacBookAir is one year old. But what are the prices for updates?

    My MacBookAir is one year. I want to upgrade IMovie, IPhoto, Garageband and ITues, But What are the prices for these upgrades. How do I get around?

    Actually, if you are updating the free iLife apps (iPhoto, iMovie & GarageBand) that came with your new Mac, the updates are free. Only if you are upgrading to newer major paid versions would you be charged.
    iTunes is always free, but is located in Apple Downloads, not the Mac App Store;
