By default, Apple’s most recent iOS devices begin taking pictures and videos in entirely new file formats when they’re updated to iOS 11-and if you want full compatibility with Photos and iCloud Photo Library, you’ll either need to update your Mac to High Sierra or change a setting on all your iOS 11 devices in order to force the devices to revert to the old file formats. In fact, the biggest user change in High Sierra is probably Photos, which gets some major interface changes and file-compatibility features. But in terms of major new features that will transform your everyday Mac experience, there just isn’t much.

High Sierra is truly a follow-on release to Sierra that offers a bunch of under-the-hood changes that will impact the Mac experience for developers today and for users in a while. (Snow Leopards do not actually live in the high Sierras, for the record.) But today’s release of macOS 10.13 High Sierra is the most Snow Leopardy of any macOS release in the last eight years. Apple has tried this same technique with other half-step updates in the past few years-Mountain Lion followed Lion and El Capitan followed Yosemite.

In the end, Snow Leopard did offer a bunch of user-interface changes (if you knew where to look), but it was definitely more about laying a new foundation.
#OS X YOSEMITE VS SIERRA MAC OS X#
It was the follow-up release to Mac OS X Leopard, and as Apple explained at the time, the focus was on under-the-hood improvements that would lead to a better, brighter future for the Mac, but be largely invisible to the upgrading user. If you were a Mac user eight years ago you may remember Snow Leopard. Note: This story has not been updated for several years. MacOS High Sierra: A mostly under-the-hood update
