Q: Sierra Compatible with MacPro Early 2009

My MacPro Desktop, Early 2009 Build 4.1 with Intel 2.66 4 Core Processor is currently running the latest version of El Capitan. Can I install the Sierra release, and if NOT, why not?

Thank you for your help.

The oldest version of the Mac Pro which can run Sierra is mid 2010.

It appears the 2009 can run Sierra if you upgrade the firmware of the 4.1 to that of a 5.1.
