On macOS 13, Continuity Camera lets people use iPhone as a camera for their Mac. This feature works automatically across all apps, and you can take it even further. New APIs power automatic camera input switching, provide access to the Desk View camera stream, and let you use AVCapture to access iPhone Camera features, such as flash mode, high-resolution capture, and photo quality prioritization.

Core ML adds new instruments and performance reports in Xcode, so you can analyze your ML-powered features. Optimize your Core ML integration with new Float16 data types, efficient output backings, sparse weight compression, in-memory model support, and new options to restrict compute to the CPU and Neural Engine.

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[4] and was released on September 25, 2017. The name "High Sierra" refers to the High Sierra region in California. Its name signified its goal to be a refinement of the previous macOS version, macOS Sierra, focused on performance improvements and technical updates rather than features.[5] This makes it similar to previous macOS releases Snow Leopard, Mountain Lion and El Capitan. Among the apps with notable changes are Photos and Safari.[4][6][7]

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.[4] The system's windowing system, Quartz Compositor, supports Metal 2.

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.[4] 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.[11][12]

The 10.13.4 update added support for external graphics processors for Macs equipped with Thunderbolt 3 ports.[18] The update discontinued support for external graphics processors in 2015 or older Macs, equipped with Thunderbolt 1 and 2 ports.

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.[20]

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.[22] Safari can also block auto playing videos from playing.[23][24] The "Reader Mode" can be set to always-on.[25] Safari 11 also supports WebAssembly.[26] The last version of Safari that High Sierra supports is 13.1.2. This version has known security issues.[27]

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.[30]

The release of macOS High Sierra 10.13.5 (and iOS 11.4) introduced support for Messages in iCloud.[31] 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.[32] In order to use the feature, the user has to enable two-factor authentication for their Apple ID.[33]

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."[34]

macOS High Sierra 10.13.0 and 10.13.1 have a critical[35] vulnerability that allowed an attacker to become a root user by entering "root" as a username, and not entering a password, when logging in. This was fixed in the Security Update 2017-001 for macOS High Sierra v10.13.1.[36]

When it was first launched, it was discovered[by whom?] 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]

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.[37]

However, if you have a Mac that supported the new update and you want to try it out, the public beta was first released in July, so you can try it out. Beware though, that as it's not a final release, it will be prone to bugs.

Alongside the previously announced features of door detection and live captions in a FaceTime call, Ventura brings some new accessibility features, such as 'buddy controller'. This will allow a user to use multiple controllers as one, making it easier to access the buttons for certain games.

Apple's web browser is seeing its tab groups improved, with Shared Tab Groups enabling your friends and family to view your tabs, or add and remove tabs. This could be useful if you're shopping for a holiday or a keyboard for example.

There's also website settings that can sync across your Apple devices, where page zooming and automatic Reader view settings will also show on your iPhone for that specific web page if you choose to.

This is a new app that was teased by Apple as launching later this year, where you can brainstorm ideas with other invited users on a blank canvas, which will work across a Mac, an iPad and an iPhone.

Apple announced macOS 13 Ventura at its Worldwide Developers Conference, paving the way for developers and public beta testers to test the new operating system for Mac before its official release in the fall.

macOS Ventura introduces a new multitasking feature called Stage Manager, a revamped Mail app, enhanced Spotlight Search, a next-generation authentication technology called Passkeys, Shared Tab Groups in Safari, and more. This version also includes redesigned System Settings menus and Continuity Camera, which allows you to use an iPhone as a webcam for your Mac.

If you're unsure what model of Mac you have, click the Apple () symbol in the menu bar at the top-left corner of the screen and then select About This Mac. You'll see the Mac model, along with the version of macOS that's currently installed.

MacRumors attracts a broad audience of both consumers and professionals interested in the latest technologies and products. We also boast an active community focused on purchasing decisions and technical aspects of the iPhone, iPod, iPad, and Mac platforms.

High Sierra emphasizes the already-existing benefits of MacOS previous system, Sierra. There are few bells and whistles, but the changes are noticeable and positive. The Apple file system is the most significant feature it brought. It enables the storage and encryption of a large number of files. Thus, it boosts performance and helps manage device memory issues.
