After2012 when Apple's Mountain Lion dropped support for older Macs, this is the first time a new desktop OS release from Apple will drop support for older hardware. If you have a Mac from early 2009, 2008 or before, you won't be able to install macOSSierra on your devices. Remember, many of these while compatible with last year's El Capitan were also missing several new features like Continuity andMetal API.

Apple is expected to keep sending out security updates to the older OS X versions for a couple of years, so at least users wouldn't have to be worried about security issues.
