macOS High Sierra

macOS High Sierra (version 10.13) is the fourteenth major release of macOS, Apple Inc.'s desktop operating system for Macintosh computers. macOS High Sierra was announced at the WWDC 2017 on June 5, 2017[3] and was released on September 25, 2017. The name "High Sierra" refers to the High Sierra region in California. Like 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]

System requirements

macOS High Sierra is supported on the following Macintosh computers:[6]

macOS High Sierra requires at least 2 GB of RAM and 14.3 GB of available disk space.

HEVC hardware acceleration requires a Mac with a sixth-generation Intel processor or newer:

External graphics processor support requires a Thunderbolt 3-enabled Mac:

It is possible to install High Sierra on many older Macintosh computers that are not officially supported by Apple. This requires using a patch to modify the install image.[7]

Changes

Apple File System

Apple File System (APFS) replaces HFS Plus as the default file system in macOS for the first time with High Sierra.[3] It supports 64‑bit inode numbers, is designed for flash memory, and is designed to speed up common tasks like duplicating a file and finding the size of a folder's contents. 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] However, whenever an Intel IGP is present, the frameworks will only direct requests to Intel IGP. In addition, audio codecs FLAC and Opus are also 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.

The time service ntpd was replaced with timed for the time synchronisation.[12]

The FTP and telnet command line programs were removed.[13]

The screen can now be locked using the shortcut Cmd+Ctrl+Q. The ability to lock screen using a menu bar shortcut activated in Keychain Access preferences has now been removed.[14]

The 10.13.4 update added support for external graphics processors for Macs equipped with Thunderbolt 3 ports.[15] The update discontinued support for external graphics processors in 2015 or older Macs, equipped with Thunderbolt 1 and 2 ports.

Starting with 10.13.4, when a 32-bit app is opened, users get a one-time warning about its future incompatibility with the macOS operating system.[16]

Final Cut Pro 7

Apple announced the original Final Cut Studio suite of programs will not work on High Sierra. Media professionals that depend on any of those programs were advised to create a double boot drive to their computer.[17]

Photos

macOS High Sierra gives Photos an updated sidebar and new editing tools.[3] Photos synchronizes tagged People with iOS 11.[3]

Mail

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.[18]

Safari

macOS High Sierra includes Safari 11. Safari 11 has a new "Intelligent Tracking Prevention" feature that uses machine learning to block third parties from tracking the user's actions.[19] Safari can also block autoplaying videos from playing.[20][21] The "Reader Mode" can be set to always-on.[22] Safari 11 also supports WebAssembly.[23] The last version of Safari that High Sierra supports is 13.1.2. This version has known security issues. [24]

Notes

The Notes app allows the user to add tables to a note.[25] A note can be pinned to the top of the list.[26]

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.[27]

Messages

The release of macOS High Sierra 10.13.5 (and iOS 11.4) introduced support for Messages in iCloud.[28] This feature allows messages to sync across all devices using the same iCloud account. When messages are deleted they are deleted on each device as well, and messages stored in the cloud do not take up local storage on the device anymore.[29] In order to use the feature, the user has to enable two-factor authentication for their Apple ID.[30]

Reception

In his September 2017 review of High Sierra, Roman Loyola, the senior editor of Macworld, gave it a provisionally positive review, calling it an "incremental update worthy of your time, eventually." Loyola expressed that the product's most significant draw was its security features, and that beyond this, the most beneficial changes lay in its future potential, saying it "doesn't have a lot of new features that will widen your eyes in excitement. But a lot of the changes are in the background and under the hood, and they lay a foundation for better things to come."[31]

Problems

macOS High Sierra 10.13.0 and 10.13.1 have a critical[32] vulnerability that allowed an attacker to become a root user by typing root in the username of the password prompt and not entering the password. This was fixed in the Security Update 2017-001 macOS High Sierra v10.13.1.[33]

When it was first launched, it was discovered that the WindowServer process had a memory leak, leading to much slower graphics performance and lagging animations, probably due to some last-minute changes in Metal 2. This was fixed in macOS 10.13.1.

macOS High Sierra 10.13.4 had an error that caused DisplayLink to stop working for external monitors, allowing only one monitor to be extended. When using two external monitors, they could only be mirrored. Alban Rampon, the Senior Product Manager for DisplayLink, stated on December 24, 2018 that the company was working with Apple to resolve the issue.[34]
