Update all of your Internet web browser plugins and extensions.
You need to update all of your third party software if there are OS X Mavericks updates that can be applied. You may need to go the third party developers' websites if there are no updates through the Mac App Store.
Also, if you have any connected third party devices, like keyboards, mice, drawing tablets, hubs, card readers, audio/video peripherals, etc, you need to update the drivers for these devices to OS X Mavericks compatible versions by going to each device maker's website and search their site for the appropriate Mavericks driver updates that are applicable and available.
