how do I add new screensaver?

If it doesn't show up in the screen savers then you either installed it in the incorrect place (~/Library/Screen Savers in your home directory or /Library/Screen Savers) or it is not a valid mac screen saver.

Provide a link to where you downloaded it from.

its for a MAC and I think the screensaver is a newer version. When I see the istalled file in downloads it shows same as the screensaver in mac.

I might try intalling some other screensaver and see if it works.

Third Party Screensavers have a fairly poor record of compatability between upgraded OS's let alone stability. It may just be a poorly designed Screensaver or a corrupted download of it.

But I feel it's the MAC OS not playing nice with other products.... 😟

Believe it or not, when it comes to third party extentions it's 99% the opposite way. Developers are often too lazy to update their software to run with new Operating Systems, be it Apple OSX or Windows. That is why the smaller companies go by the wayside. Just because it's a Nike Screensaver does not mean that the product is up to the standard of their shoes. I would go with your earlier suggestion to try some other third party screensavers and see how they work. I know my favorite was left behind about 4 OSXs ago.

Just double-click on the screensaver - you will be asked if you want to install it. You can also manually place it in one of the /Library/Screen Savers folders.

If the screensaver is an older version, you will probably need to update it for Lion. Is that screensaver for the Mac, or the iPod?
