MacBook, OS X 10.11
The only 2009 models of Mac that you can install macOS Sierra on are the Macbook and the iMac. Unfortunately, if your late 2009 computer is not one of these, it isn't possible to update your operating system any further than macOS El Capitan.
See: How to upgrade to macOS Sierra - Apple Support
You can upgrade to macOS Sierra from OS X Lion or later on any of the following Mac models. Your Mac also needs at least 2GB of memory and 8.8GB of available storage space.
