How can I upgrade my Mac OS X 10.5.5 to something that works? I'm getting the message from many websites that they no longer support the browser I'm using, but I don't know how to go about upgrading. Do I have to go through the OS sequentially?

Help, please. I'm receiving the message constantly that websites don't support the browser I'm using. I've tried to upgrade both Safari and Firefox, and those upgrades won't work with my OS X 10.5.5. I know I have to upgrade that, but how? Do I need to upgrade sequentially -- i.e., through each variation all the way up to Mountain Lion or can I just go straight to the latest? I'm guessing I need to buy that OS, but want to make sure I get the right one and that it will work on my MacBook (the one with the Intel Core). Can someone offer any guidance? With many thanks...

MacBook, Mac OS X (10.5.5)

You need to upgrade to Snow Leopard first. Contact Apple to buy a Snow Leopard installation DVD.

Make sure your system meets Snow Leopard's requirements:

Mac OS X v10.6 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 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

Once you have Snow Leopard, you can upgrade to whatever your MacBook will support.

There is no need for sequential upgrades. The reason Snow Leopard is a prerequisite for further upgrades is that it includes the App Store. All OS versions subsequent to Snow Leopard are distributed that way.
