  • Best Answer:

    No. The Snow Leopard DVD is a full installer.

    You should make sure that you meet the hardware requirements for Snow Leopard though: 1GB RAM and an Intel processor with a DVD Drive and 5 GB of disk space are the main requirements.

  • OS 10.6 (Snow Leopard) only works on Intel-based Macs, with a minimum of 1GB of memory.

    If you have an Intel-based Mac, you can upgrade directly from OS 10.4.11 (Tiger) to Snow Leopard. You do not need to upgrade to OS 10.5 first (good thing, as it is extremely difficult to find OS 10.5 for sale anymore).

    I upgraded from OS10.4.11 directly to Snow Leopard using the retail disk. However, I upgraded a cloned copy of my OS 10.4.11 partition. That way I can boot from either OS 10.4.11 or from OS 10.6. The reason? If an app or driver for a scanner or printer does not work in OS 10.6, I could revert back to OS 10.4.11 (by starting up from the OS 10.4.11 partition) in order to use the scanner, printer or app until I found drivers and apps that work in OS 10.6.
