Upgrading to Mavericks

To upgrade to Mavericks you must have Snow Leopard 10.6.8 or Lion installed. Download Mavericks from the App Store. Sign in using your Apple ID. Mavericks is free.

Happy Holidays to you and your family.

You do NOT Have To Upgrade to Mavericks, now or anytime in the future. There are many Apple Mac users that are still running Snow Leopard or even previous version of OS X and many more that are still running Lion and Mt Lion.

There is nothing written in stone that you have to Upgrade to any newer version of OS X. That is completely up to you.

Your Mac will run Mavericks if you choose to upgrade to it.

You are welcome.
