macOS High Sierra (version 10.13) is the fourteenth major release of macOS, Apple Inc.'s desktop operating system for Macintosh computers. The successor to macOS Sierra, it was announced at the WWDC 2017 on June 5, 2017.[3]
The name "High Sierra" refers to the High Sierra region in California. As with Snow Leopard, Mountain Lion and El Capitan, the name also alludes to its status as a refinement of its predecessor, focused on performance improvements and technical updates rather than user features. Among the apps with notable changes are Photos and Safari.[3][4][5]
Contents
System requirements
macOS High Sierra has the same requirements as its predecessor:[6]
- iMac: late 2009 or newer
- MacBook/MacBook (Retina): late 2009 or newer
- MacBook Pro: mid-2010 or newer
- MacBook Air: late 2010 or newer
- Mac Mini: mid-2010 or newer

A workaround exists to install macOS High Sierra on some Mac computers that are no longer officially supported.[7]
HEVC hardware acceleration requires a Mac with a sixth-generation Intel processor or newer:
- iMac: late 2015 27" or newer, 2017 21.5" or newer
- MacBook: early 2016 or newer
- MacBook Pro: late 2016 or newer
Changes
System
Apple File System
Apple File System (APFS) replaces HFS Plus as the default file system in macOS.[3] It supports 64‑bit inode numbers, is designed for flash technology, and is designed to make common tasks like duplicating a file and finding the size of a folder’s contents faster. It also has built‑in encryption, crash‑safe protections, and simplified data backup on the go.[8]
Metal 2
Metal, Apple's low-level graphics API has been updated to Metal 2. It includes virtual-reality and machine-learning features, as well as support for external GPUs.[3] The system's windowing system Quartz Compositor supports Metal 2.
Media
macOS High Sierra adds support for High Efficiency Video Coding (HEVC), with hardware acceleration where available, as well as support for High Efficiency Image File Format (HEIF). Macs with the Intel Kaby Lake processor offer hardware support for Main 10 profile 10-bit hardware decoding, those with the Intel Skylake processor support Main profile 8-bit hardware decoding, and those with AMD Radeon 400 series graphics also support full HEVC decoding.[3] In addition, audio codecs FLAC and Opus will also be supported, but not in iTunes.[9][10]
Other
Kernel extensions ("kexts") will require explicit approval by the user before being able to run.[11]
The Low Battery notification and its icon were replaced by a flatter modern look.[citation needed]
The time service ntpd was replaced with timed for the time synchronisation[citation needed].
In November 2017, a private security company discovered a major vulnerability in High Sierra that allows anyone to gain full root access by attempting to login as "root" multiple times with no password.[12] Apple released a patch on November 29, 2017.[13]
Applications
Photos
macOS High Sierra gives Photos an updated sidebar and new editing tools.[3] Photos synchronizes tagged People with iOS 11.[3]
Mail has improved Spotlight search with Top Hits.[3] Mail also uses 35% less storage space due to optimizations, and Mail's compose window can now be used in split screen mode.[14]
Safari
Safari has a new "Intelligent Tracking Prevention" feature which uses machine learning to block third parties from tracking the user's actions.[15] Safari can also block autoplaying videos from playing.[16][17] The "Reader Mode" can be made to be always turned on.[18] In addition, Safari 11 will also support WebAssembly.[19]
Notes
The Notes app allows the user to add tables to a note.[20] A note can be pinned to the top of the list.[21]
Siri
Siri now uses a more natural and expressive voice. It also uses machine learning to understand the user better. Siri synchronizes information across iOS and Mac devices so the Siri experience is the same regardless of the product being used.[22]
