  • Yes. It can be installed without an optical drive. (Note that more recent Macs with OS 10.7 or later may not run the Snow Leopard Installer. If that is the case, try option 3 below.)

    To install Snow Leopard on older Mac (but with Intel processor):
    1) use a spare USB flash drive (at least 8GB in size that will be reformatted and erased) and a second Mac with an optical drive, or
    2) have Mac to be upgraded connected to a Local Area Network with another Mac (or Windows XP PC) that does have an optical drive.

    Option 1 (easiest):
    1) Use Disk Utility to reformat the USB drive as "Mac OS Extended (Journaled)" with the GUID partition option (if available . . . more recent versions of Disk Utility automatically do the GUID partition option).
    2) On a Mac with working optical drive, use Disk Utility to RESTORE the DVD to the USB flash drive.
    3) Connect USB flash drive to Mac to be upgraded. Restart Mac and hold option key. Select "Snow Leopard DVD" (which is now the name of USB flash drive).
    4) Follow installation instructions.

    Option 2 (more hassle than it may be worth):
    The Snow Leopard DVD has "Remote Install OS X" software on it for remote install. Place DVD in optical drive of a Mac or Windows XP PC on same network as Mac to receive Snow Leopard. Find the software and follow the instructions.

    Option 3 (if Snow Leopard installer will not run on Mac because Mac is too new):
    (This requires another older Intel-based Mac that is able to run the installer.) Create a small partition (at least 12GB) that is formatted as "Mac OS Extended (Journaled)" with the GUID partition option (partition can be on an external drive or USB flash drive). Install Snow Leopard to the partition. Use Disk Utility to make DMG image of partition OR move external/USB drive to newer Mac. If DMG image was created, copy to newer Mac, and restore DMG to a partition on newer Mac. Restart Mac, hold option key, and select partition with Snow Leopard.

  • well to be honest all you need to do is find a computer with a CD Drive, view all files on the Drive, press ctrl+a, ctrl+c and copy them to a usb drive
