Note: Although this article was written for mac OS Sierra (10.12), much of it still applies to mac OS High Sierra (10.13) which was released in September 2017.High Sierra's system requirements are the same, except that High Sierra now requires 14.3 GB of available disk space, and a minimum of OS X Mountain Lion (10.8) to do a direct-upgrade installation.Certain older Mac models are still limited to Lion (10.7), which has not been getting security patches since Yosemite was released two years ago.Some early Intel Macs released in 2006 are stuck with Snow Leopard (10.6), which hasn't received security updates since the release of Mavericks three years ago.

With the release of Sierra, Apple decided to drop support for some Mac models that were supported by several previous releases of the Mac operating system.For now, Flash and Java also officially support Mavericks and later.
