i have leopard 10.5 and i want snow leopard osx 10.6

To upgrade from OS X 10.5.8, you must first buy Snow Leopard by calling the phone number in the Apple Online Store: 800-MY-APPLE (in the US). Snow Leopard costs $20, or $30 for a five user license. Do not obtain Snow Leopard from any source other than Apple.

Make sure your system meets Snow Leopard's requirements:

Mac OS X 10.6 "Snow Leopard" System Requirements

To install Snow Leopard for the first time, you must have a Mac with:

• An Intel processor
• An internal or external DVD drive, or DVD or CD Sharing
• At least 1 GB of memory (RAM) (additional RAM is recommended)
• A built-in display or a display connected to an Apple-supplied video card supported by your computer
• At least 5 GB of disk space available, or 7 GB of disk space if you install the developer tools

After you install Snow Leopard you can decide if you want to upgrade OS X to the latest version, Mountain Lion. Mountain Lion is available in the Mac App Store, which is available to you after upgrading to Snow Leopard.

What are the benefits of upgrading from OS 10.5.8? I've been getting warnings from Firefox and Chrome that my system isn't as secure as it could be. Is that it? Anything else?

Since your question has nothing to do with the orginal question asked on this thread, you really should have started you own thread for it.

I will answer and yes the new versions of OS X are more secure.

I would not be concerned about those warnings. If a banking website or some other secure system requires an updated browser, it will refuse to work with anything else and you won't have a choice.

You need Snow Leopard for almost everything having to do with iOS devices.

I still use Tiger for a lot of my work. If anyone tries to hack into it, go ahead, make my day.

OK, that makes sense. Thanks for the information.
