macOS High Sierra is the final version of macOS to support the Unibody iMac and the Polycarbonate Unibody MacBook, as its successor, macOS Mojave, drops support for the late 2009 and final models.

macOS High Sierra is the first to run on a Mac with T2 Security chip.

==System requirements== All Macs that supported macOS Sierra support macOS High Sierra.<ref>{{cite web|url=https://support.apple.com/ht201475|title=How to download macOS High Sierra|publisher=Apple|archive-url=https://web.archive.org/web/20180201071509/https://support.apple.com/ht201475|archive-date=February 1, 2018}}</ref> *iMac (Late 2009 or later) *MacBook (Late 2009 or later) *MacBook Air (Late 2010 or later) *MacBook Pro (Mid 2010 or later) *Mac Mini (Mid 2010 or later) *iMac Pro (2017) *Mac Pro (Mid 2010 or later)

macOS High Sierra requires at least 2 GB of RAM and 20.12 GB of available disk space.

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.<ref>{{Cite web |url=http://dosdude1.com/highsierra/ |title=macOS High Sierra Patcher Tool for Unsupported Macs |access-date=October 15, 2017 |archive-date=October 15, 2017 |archive-url=https://web.archive.org/web/20171015095213/http://dosdude1.com/highsierra/ |url-status=live }}</ref>

==Changes==

=== Default wallpaper === The default desktop picture depicts North Lake in the High Sierra biome.

===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.<ref name="keynote"/> 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.<ref>{{cite news|url=https://9to5mac.com/2016/06/13/apple-file-system-apfs|title=Apple File System (APFS) announced for 2017, scales 'from Apple Watch to Mac Pro' and focuses on encryption|date=June 13, 2016|work=9to5Mac|access-date=September 12, 2017|language=en-US|url-status=live|archive-url=https://web.archive.org/web/20170328195315/https://9to5mac.com/2016/06/13/apple-file-system-apfs|archive-date=March 28, 2017}}</ref>

====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.<ref name="keynote"/> 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.<ref name="keynote"/> 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.<ref>{{cite web|url=http://www.macotakara.jp/blog/news/entry-32693.html|title=iOS 11、macOS High Sierra：FLAC、Opus、HOA（3Dサウンド）をサポート|website=Macお宝鑑定団 blog（羅針盤）|date=June 8, 2017 |language=ja|trans-title=iOS 11, macOS High Sierra: Supports FLAC, Opus, HOA (3D sound)|archive-url=https://web.archive.org/web/20170914215717/http://www.macotakara.jp/blog/news/entry-32693.html|archive-date=September 14, 2017|url-status=live}}</ref><ref>{{cite AV media|url=https://developer.apple.com/videos/play/wwdc2017/501|title=What's New in Audio - WWDC 2017 - Videos - Apple Developer|archive-url=https://web.archive.org/web/20170914220513/https://developer.apple.com/videos/play/wwdc2017/501|archive-date=September 14, 2017|url-status=live}}</ref>

HEVC hardware acceleration requires a Mac with a sixth-generation Intel processor or newer (late 2015 27-inch iMac, mid 2017 21.5-inch iMac, early 2016 MacBook, late 2016 MacBook Pro or iMac Pro).

====Other==== In High Sierra, kernel extensions ("kexts") require explicit approval by the user before being able to run.<ref>{{cite web|url=https://developer.apple.com/library/content/technotes/tn2459/_index.html|title=Secure Kernel Extension Loading|date=June 19, 2017|website=Apple Developer|access-date=June 24, 2017|archive-date=July 23, 2017|archive-url=https://web.archive.org/web/20170723011811/https://developer.apple.com/library/content/technotes/tn2459/_index.html|url-status=live}}</ref>

==Reception== Roman Loyola, the senior editor of ''Macworld'', gave High Sierra a provisionally positive review in September 2017, 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."<ref>{{cite news|url=https://www.macworld.com/article/3226383/macs/macos-high-sierra-review.html|title=macOS High Sierra review: Incremental update worthy of your time, eventually|work=Macworld|date=September 25, 2017|access-date=November 1, 2018|archive-date=November 16, 2018|archive-url=https://web.archive.org/web/20181116061725/https://www.macworld.com/article/3226383/macs/macos-high-sierra-review.html|url-status=live}}</ref>

When it was first launched, it was discovered{{By whom|date=October 2018}} 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.{{citation needed|date=December 2020}}

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.
