's desktop operating system for Macintosh computers. The successor to macOS Sierra, it was announced at the WWDC 2017 on June 5, 2017, and it was released on September 25, 2017. 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.

A workaround exists to install macOS High Sierra on some Mac computers that are no longer officially supported as long as they are equipped with a CPU that supports SSE4. 1. HEVC hardware acceleration requires a Mac with a sixth - generation Intel processor or newer : iMac : late - 2015 27 '' or newer, mid-2017 21.5 '' or newer MacBook : early - 2016 or newer MacBook Pro : mid-2016 or newer iMac Pro External graphics processor support requires a Thunderbolt 3 - enabled Mac : MacBook Pro : late - 2016 or later iMac : mid-2017 or later iMac Pro Changes System Apple File system Apple File System ( APFS ) replaces HFS Plus as the default file system in macOS for the first time with High Sierra. 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. 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. 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. However, whenever an Intel IGP is present ( such as macbooks ), the frameworks will only direct requests to Intel IGP. In addition, audio codecs FLAC and Opus are also supported, but not in iTunes. Other Kernel extensions ( `` kexts '' ) will require explicit approval by the user before being able to run. 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. The FTP and telnet command line programs were removed. 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. The 10.13. 4 update added support for external graphics processors for Macs equipped with Thunderbolt 3 ports. 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. Applications Photos macOS High Sierra gives Photos an updated sidebar and new editing tools. Photos synchronizes tagged People with iOS 11. Mail Mail has improved Spotlight search with Top Hits. Mail also uses 35 % less storage space due to optimizations, and Mail 's compose window can now be used in split - screen mode. Safari Safari has a new `` Intelligent Tracking Prevention '' feature that uses machine learning to block third parties from tracking the user 's actions. Safari can also block autoplaying videos from playing. The `` Reader Mode '' can be set to always - on. Safari 11 also supports WebAssembly. Notes The Notes app allows the user to add tables to a note. A note can be pinned to the top of the list. 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. Messages With the release of macOS 10.13. 5 messages can now be stored in the cloud along with iOS 11.4, this allows messages to sync across all devices using the same iCloud account, when messages are deleted they are deleted on each device as well, messages stored in the cloud do not take up storage on Macs anymore. Reception Reception of macOS High Sierra was positive. Problems macOS High Sierra 10.13. 0 and 10.13. 1 have a critical vulnerability that allowed an attacker to become a root user by not entering the password. This was fixed in the Security Update 2017 - 001 macOS High Sierra v10. 13.1. When it was first launched, it was discovered that the process named `` WindowServer '' 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 quickly fixed in macOS 10.13. 1. macOS High Sierra 10.13. 4 had an error that caused Display Link to stop working for external monitors. Only 1 monitor is able to be extended, if using 2 external monitors, they can only be mirrored. This also seems to be an issue with the beta version of Mojave. Display link have said they are working with Apple to resolve the issues but as of the most recent macOS High Sierra update, the issue still persists.
