Have an iMac with intel processor 1.83 GHz, 512MB memory, version 10.4.11. Trying to upgrade using 10.5.4 using Install Discs from other computer but message says the software can not be installed on this computer. Not sure why not.

    Those disks are specific to the model of Mac they came with. If you don't have a retail Mac OS X 10.5 DVD, phone the online Apple Store and order a Mac OS X 10.6 one.

    That's because you cannot use installer discs from a different computer. If you wish to upgrade to Leopard, then you need to buy a retail copy on eBay or Amazon.com or searching Google for a vendor. Or you can also purchase and install Snow Leopard, although you will first need to erase the drive. You will also need to make a backup of your Tiger system. And you will need to upgrade your RAM from 512 MBs to 1 or 2 GBs.

     

    You can purchase Snow Leopard by contacting Customer Service: Contacting Apple for support and service - this includes international calling numbers. The price is $19.99 plus tax. You will receive physical media - DVD - by mail.

     

    Third-party sources for Snow Leopard are:

     

    Snow Leopard from Amazon.com

    Snow Leopard from eBay

     

    After you install Snow Leopard you will have to download and install the Mac OS X 10.6.8 Update Combo v1.1 to update Snow Leopard to 10.6.8 and give you access to the App Store.

    Snow Leopard General requirements

     

      1. Mac computer with an Intel processor

      2. 1GB of memory

      3. 5GB of available disk space

      4. DVD drive for installation

      5. Some features require a compatible Internet service provider; fees may apply.

      6. Some features require Apple’s MobileMe service; fees and terms apply.

    It's been pulled from the online store & Apple Stores, so you have to call Apple to buy it, last I heard.

    Call Apple Sales...in the US: 1-800-MY-APPLE. Or Support... 1-800-275-2273

     

    Other countries...
