Q: upgrade from safari to maverick

Safari is a browser while Mavericks is an Operating System. Can you provide a bit more detail on what you are trying to accomplish?

I think you mean from Snow Leopard to Mavericks.

Upgrading to Mavericks

You can upgrade to Mavericks from Lion or directly from Snow Leopard. Mavericks can be downloaded from the Mac App Store for FREE.

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. The file is quite large, over 5 GBs, so allow some time to download. It would be preferable to use Ethernet because it is nearly four times faster than wireless.

     Are my applications compatible?

         See App Compatibility Table - RoaringApps.

Open the Mac App Store and try downloading Mavericks. If you get told it's incompatible and if desired, choose About this Mac from the Apple menu, check if the computer has at least a Xeon or Core 2 Duo(not Core Duo) CPU and 2GB of RAM, and if it does, click here and order a download code for Lion 10.7.

Back up your data before upgrading. Mac OS X 10.7 and newer don't support PowerPC programs such as versions of Microsoft Office prior to 2008.
