    Ok. Go to the Apple Menu click about this Mac and it should tell you your OS.

    10.0
    10.1 (Puma)
    10.2 (Jaguar)
    10.3 (Panther)
    10.4 (Tiger)
    10.5 (Leopard)
    10.6 (Snow Leopard)

    If you have Panther or lower you will most likely not to be able to install S/L. Remember you must have a Intel Mac to install it.
