If there was an essential program on my Mac running Leopard, that was Onyx, as it allows us to maintain the Mac quickly and easily, and above being highly effective to eliminate all the excess.
With Snow Leopard we could not do it until they have released Onyx 2.1, with support for Snow Leopard. They have given me great joy because spending it once a week is luxurious and is totally recommended.
The program is still free, and therefore, it becomes one of the many indispensable in our Applications folder.
