Answer:

That's correct, your Mac is too old to support Sierra or High Sierra. You may be able to upgrade to El Capitan if it is mid 2007 or newer:

get El Capitan from the App Store

If your Mac is not Compatible with Sierra but you Have Not Upgraded to El Capitan - https://discussions.apple.com/docs/DOC-10692


OS X El Capitan requires one of the following Mac models and versions of OS X. It also requires at least 2GB of memory and 8.8GB of storage space.


iMac (Mid 2007 or newer) <--- I'm not sure if that is your machine or not.
