Much of the software in Mac OS X was extensively rewritten for this release in order to take advantage fully of modern Macintosh hardware.
New programming frameworks, such as Open CL, were created, allowing software developers to use graphics cards in their applications.
This is also the first Mac OS release since System 7.1.1 that does not support Macs using Power PC processors, as Apple now intends to focus on its current line of Intel-based products.
And even if you’re unlikely to notice all of them, some are pretty monumental for the operating system’s future.
You can install the public beta for High Sierra as of today.
