Refinements Made to Popular Apps Like Photos, Safari, Mail and More
San Jose, California — Apple today previewed macOS High Sierra, the latest version of the world’s most advanced desktop operating system, delivering new core storage, video and graphics technologies that pave the way for future innovation on the Mac. macOS High Sierra offers an all-new file system, support for High-Efficiency Video Coding (HEVC) and an update to Metal, Apple’s advanced graphics technology that powers everything from machine learning to virtual reality content creation. macOS High Sierra also includes a number of refinements to the apps Mac users enjoy every day, including Photos, Safari and Mail.
“macOS High Sierra delivers important forward-looking technologies and new opportunities for developers wanting to tap into the power of machine learning and create immersive VR content on the Mac,” said Craig Federighi, Apple’s senior vice president of Software Engineering. “The core technology innovations in macOS High Sierra, combined with our advances in hardware, will continue to push the Mac forward in exciting new ways.”
Powerful New System Technologies
Apple File System (APFS) features enhanced performance, security and reliability of data and provides a foundation for future storage innovations. An advanced architecture optimized for today’s massive storage technologies, APFS makes common operations such as copying files and directories instantaneous, helps protect data from power outages and system crashes and keeps files safe and secure with native encryption. macOS High Sierra also maintains complete read-and-write compatibility with previously formatted HFS drives and data and is designed to accommodate future advancements in storage technology.
Support for industry-standard HEVC (H.265) enables video streaming and playback of 4K video files at incredible quality that are also up to 40 percent smaller than with the current H.264 standard.1 With HEVC, Apple is enabling high-quality video streaming on networks where only HD streaming was previously possible, while hardware acceleration on the new iMac and MacBook Pro deliver incredibly fast and power-efficient HEVC encoding and editing.
Metal is the fastest, most efficient way to tap into GPU power on the Mac. Metal 2 features a refined API and improved performance that help developers accelerate their apps. It adds support for machine learning used in speech recognition, natural language processing and computer vision. The combination of Thunderbolt 3 and Metal 2 allows the most demanding users to access powerful external GPUs. An External Graphics Developer Kit gives developers all the hardware and software they need to optimize their apps.
Drawing on the performance of Metal 2 and the latest Mac hardware, macOS High Sierra adds support for VR content creation for the first time, enabling developers to create immersive gaming, 3D and VR content on the Mac. Leading VR companies are joining Apple to drive VR innovation on the Mac with features coming later this year — Valve is optimizing their SteamVR platform for macOS and enabling connection of the HTC Vive headset, while Unity and Epic are bringing their VR development tools to macOS. Also later this year, Final Cut Pro X will add support for professional 360-degree workflows with the ability to import, edit and export 360-degree video.
Photos in macOS High Sierra adds a new always-on sidebar that presents albums and organization tools. A redesigned Edit view includes powerful new tools like Curves, for fine-tuning of color and contrast, and Selective Color, for making adjustments within a defined color range. Live Photos can now be edited with fun effects and Memories curates user photos and videos around several new topics. Photos now supports external editors, so Photoshop, Pixelmator and other apps can launch directly within Photos, with edits saved back to the Photos library. And for the first time, support for third-party project extensions gives users access to printing and publishing services, such as Animoto, ifolor, Shutterfly, WhiteWall and Wix, from right within the Photos app.
- Safari can automatically use Reader to open articles in a clean, uncluttered format, while Autoplay Blocking stops media with audio from automatically playing in the browser.
- Intelligent Tracking Prevention in Safari uses machine learning to identify and remove the tracking data that advertisers employ to follow users’ web activity.
- Mail search gets faster and easier with Top Hits, which puts the most relevant results at the top of a user’s message list.
- Siri on the Mac responds with a natural and more expressive voice, and when using Apple Music, it learns music preferences, creates custom playlists and answers music trivia.
- Notes adds simple tables, where a user can type in cells, make edits and move rows and columns.
- Spotlight provides flight status information, including departure and arrival times, delays, gates, terminals and even a map of the flight path.
- iCloud File Sharing lets users share any file stored in iCloud Drive and collaborate with other people.
- The developer preview of macOS High Sierra is available to Apple Developer Program members at developer.apple.com starting today, and a public beta program will be available to Mac users in late June at beta.apple.com. macOS High Sierra will be available this fall as a free software update from the Mac App Store. For more information, visit apple.com/macos/high-sierra-preview.
- Registered Apple Developer Program members can get everything they need to optimize their apps for external graphics with the External Graphics Developer Kit for $599 (US). It includes a Thunderbolt 3 external PCI expansion chassis, AMD Radeon RX 580 graphics card with 8GB VRAM and USB-C hub.

Ever find your computer going to sleep on you when you don’t want it to? Or starting up your screen saver while you’re trying to work?
Good news: MacBooks and iMacs make it easy to create screen saver and display sleep settings that perfectly suit your needs.
Assuming you’re using Max OS X 10.6.x, aka Snow Leopard, you can change all of your display settings by clicking the “System Preferences” icon in your dock. It looks like this.

Screen Saver
In the System Preferences menu, click on “Desktop & Screen Saver.” Select the Screen Saver tab at the top. OS X comes with 8 built-in screen savers that you can choose from; these are the ones with the kinds of snazzy graphic effects that Apple just loves to show off. If you’re feeling particularly adventurous, you can select the “Options” button and customize things like the screen saver’s speed and colors.
Under the built-in screen savers, you’ll see a list called Photos. Here, you can choose to use some built-in, high-res photos display as your screen saver, or you can use your own pictures. (Your pictures must exist inside iPhoto for System Preferences to be able to use them.) If you select the “Shuffle” option at the very top of the list, a new window will pop up to let you select which of your pictures to include in the rotation.
One very important option in the Screen Saver window is the “Start Screen Saver” slider. Use this to tell your computer how long it should wait, after your last activity, before automatically starting up the screen saver. And since the system sleep options are on similar timers, typically you’ll want your system to go to sleep a good while after your screen saver starts up.
Putting Your Computer to Sleep
Back out on the main System Preferences menu, click on “Energy Saver.” These settings may seem unnecessary to new users, but they’re really quite essential to keeping your system running smoothly for a long, long time.
There are a lot of options on this screen, but I’m only going to focus on the ones you need to worry about. The first thing MacBook users will notice are the two tabs at the top labeled “Battery” and “Power Adapter.” iMac users only have the Power Adapter to worry about. Both have their own energy settings. Your Power Adapter can be set to go to sleep significantly longer than your Battery; after all, when you’re running on battery power, every second counts!
There are two sliders: one for the monitor, and one for the entire computer. Generally you’ll want your monitor to go to sleep much sooner than your entire system, because a lot of times you might be running something in the background (such as a big download) that you don’t want interrupted, but you don’t need to keep a close eye on it. It’s best to put the screen to sleep as early as you’re comfortable with, because monitors are power hogs and every minute you use it is one minute less that it has left to live (in the long run).
For the power adapter, I generally set my screen to go to sleep after 15 to 30 minutes, and my system at least an hour later. Many times, I leave my system on “Never,” so that it won’t ever shut down. This is a bit more strenuous on the computer and the hard drive, but it’s good for things like Time Machine’s automated backups.
When running strictly off of the battery, I let my display sleep after 2 minutes, and my laptop after 10 minutes, to conserve as much of the battery’s juice as possible. This makes the screen saver moot, since it’s set to kick in after 5 minutes, but that’s okay. Screen savers drain battery power, too.
These settings work for me, but they aren’t what’s best for everyone. Depending on what you use your computer for, you should tweak the default settings so that your computer is running at optimum conditions for your needs.
