Macintosh: Upgrade (Not Clean Install)

Posted on 2011-10-04
Last Modified: 2012-05-12

1) I am used to with the Microsoft Window
2) I am not familiar with the Macintosh OS

3) I have a MacMini with the operating system --> Mac OS X 10.5.8

4) I want to upgrade it to Mac OS X Lion (Not Clean Install)

5) My Assumption:
First Step: From Leopard (Mac OS X 10.5.8) to Snow Leopard (Mac OS X 10.6.8)
Second Step: From Snow Leopard (Mac OS X 10.6.8) to Lion (Mac OS X 10.7.8)

6)I understood to do the "second step"; but I am still "not clear" to do the "first step"

7) My questions: Would somebody show me how to do the above "first step"? (From Where would I get the "file"?) (Could I make a bootable DVD with the file?) (If I do not make a bootable DVD (after downloading the files), how to execute it?

8) Thank you

    Hi tjie!

    Clarifying my answer to your question from yesterday, to answer the "First step"-question:

    - Unfortunately, SnowLeopard is not available online for downloading.

    - You need a physical Install DVD to install/upgrade to SnowLeopard (Mac OS 10.6)

    - You can order an Install DVD here:
    (it's $29 and this one links to the U.S. store, but the same item exists in AppleStores around the world).
    Or if you find a used copy on eBay, or similar, you can use that.

    - With your SnowLeopard Install DVD inserted in your Mac mini you go for Upgrade, and your Mac mini will reboot from that DVD and you just follow the on-screen instructions to upgrade.
    (Please make sure you have a fresh backup of your files before proceeding. That makes life much simpler if something would go wrong during the upgrade.)

    - After the upgrade, run Software Update (from the Apple menu) to update to 10.6.8.

    - Then, do "Second step".

    Best regards,
    Jens Helander
