macOS High Sierra: The Macworld review
Here's our full review of macOS High Sierra. High Sierra is mostly an under-the-hood upgrade that sets the Mac up for the future. There are cool features in Photos and Notes, and Safari 11 has controls for autoplay videos. Read our review to learn more.
A new file system
Ever since System 8, the Mac has used the HFS+ file system to keep our documents and directories running smoothly, but at last year’s WWDC, a new Apple File System (APFS) was announced. It made it into iOS with the iOS 10.3 update, and with High Sierra it’s also coming to the Mac. But where the changes to iOS are largely behind the scenes, you’ll really get it see it in action in the new macOS.
One of the main tenets of High Sierra, APFS will be new the new default file system, bringing an advanced 64-bit architecture and a responsive design to cut down on the time it takes to do common tasks. Apple VP Craig Federighi quickly demoed how fast files are copied, and it should save quite a bit of time, even on older Macs. APFS also brings some heavy-duty security, including built‑in encryption, crash‑safe protections, and simplified data backup on the go.
APFS works with SSDs, and when you upgrade to High Sierra, the SSD will automatically be converted from HFS+ to APFS. APFS does not work with Fusion Drives and hard drives, so those storage devices will continue to use HFS+.
A recent AppleInsider report states that some games have problems running on APFS. Unity recommends that developers working on games based on the Unity Engine (such as Cities: Skylines) should not upgrade to High Sierra or upgrade to Unity 5.5. AppleInsider also states that other games that have problems since the APFS upgrade include Civilization V, Counter-Strike: Global Offensive, Half-Life 2, and Team Fortress 2.
Learn more about APFS in our APFS FAQ.
Better Photos
Photos is rapidly becoming one of the most used apps on our Macs, and in High Sierra it looks we’ll be spending even more time with it. A slew of new features await us in the new OS, including better organization, looped Live Photos, and new Memories categories. It’ll also be easier to identify who’s in your photos with more accurate People identification and cross-device syncing for albums.
But the coolest feature may be a set of new built-in editing tools. Photos already lets us make some awesome adjustments to our snapshots, but High Sierra seriously ups the game with powerful pro-level tools—like a curves palette for fine-tuning color and contrast, a selective color dropper to home in a specific hue, and new filters that will make your photos fit for an art gallery. And for all your gallery- and album-worthy photos, Apple has now partnered with third-party apps to give you more publishing and printing options.
Speedier, smarter Safari
Apple’s browser always gets a tune-up whenever a new version of macOS comes out, but this time around Federighi says the improvements coming in High Sierra actually make it the world’s fastest desktop browser. It features 80 percent faster JavaScript performance when compared to Chrome, which should help us surf way quicker. We have benchmarks of the Safari 11 beta, and it definitely is the fastest Mac browser available
But we’re more interested in two new features that address what it’s like to use the Internet in 2017. The first will eliminate one of the more annoying features of the modern web: autoplay videos. Where Safari in Sierra tells you which tab is playing audio, in High Sierra, it will shut the video down before it can start. Autoplay blocking will detect which sites are delivering unwanted videos, and then press the pause button for you. See how it works.
Along with our ears, the new Safari will also protect our privacy. A new system of intelligent tracking will use machine learning to identify prying advertising trackers that track your online behavior and remove the cross-site tracking data they leave behind. That means you won’t get hit up with three dozen vacuum ads the next time you buy one on Amazon.
Safari 11 also has the option to let you view sites in Reader mode all the time. Here’s a look at the always-on Reader mode.
Smoother video
We watch a lot of video on our Macs, and High Sierra is making the experience even better. In addition to supporting 4K where available, it’s also upgrading to the new industry standard, High Efficiency Video Coding (or H.265 for short). The new system compresses video up to 40 percent more the H.264, the current video standard. Under the new codec, videos will stream smoother and take up less space, both of which will make experience much more pleasant. And if you’re a video creator, the new standard will also be built into Pro Tools so your projects will be able to take full advantage of it right from the start.
Next-level Metal
When Metal was introduced in El Capitan, it brought a slew of under-the-hood changes to make games and graphics sing, and now it’s ready to deliver the next generation, appropriately called Metal 2. The new technology will open up games to a whole new world of power, with a new API and powerful tools for developers. Metal 2 will bring 10 times the draw call throughput that Metal delivered, enabling graphics that are far more robust while adding external GPU support for hard-core gamers.
But Metal 2 also brings support for something sorely missing from today’s Macs: virtual reality. High Sierra lets developers create interactive and immersive virtual reality experience on the Mac for the very first time that will work with the HTC Vive and Unreal Engine for VR. And to show how serious it is about VR, Apple is even offering developers an external graphics dev kit to get started, featuring a Thunderbolt 3 enclosure with an AMD Radeon RX 580 GPU. You know, until the iMac Pro arrives in December.
You can learn more about Metal 2 by watching these Apple videos from the Worldwide Developers Conference. These presentations are targeted at developers.
Software issues
Apple announced at WWDC 2017 that the company will start to phase out support for 32-bit software in macOS. In January 2018, new apps submitted by developers to the App Store must be 64-bit apps. Also, all apps and app updates must be 64-bit by June 2018. Eventually, 32-bit support will no longer exist in macOS, probably in a version after High Sierra.
That’s important for developers to note, but it’s also important for users. If you have old software you like to use and never update, it’s possible they are 32-bit apps and they won’t work in a future version of macOS. Now’s the time to update those apps and get used to them, or find alternatives.
With the macOS 10.3.4 update, Apple has implemented alerts that let you know if an app that you are opening is a 32-bit app. The alerts have a Learn More link that takes the user to a KnowledgeBase article explaining the 32- to 64-bit transition. Learn more about the 32-bit alerts.
If you're using Apple's Final Cut Studio and Logic Studio, Apple is sending notifications to registered user regarding compatibility issues with High Sierra. According to MacRumors, Apple is informing those users that Final Cut Studio and Logic Studio are 32-bit apps that 'will not launch on a computer running macOS High Sierra.' Users running these two apps will need to upgrade to Final Cut Pro X an Logic Pro X.
The following pro apps are compatible with High Sierra:
Final Cut Pro X 10.3.4 or later
Motion 5.3.2 or later
Compressor 4.3.2 or later
Logic Pro X 10.3.1 or later
MainStage 3.3 or later
If you use Microsoft Office with the macOS High Sierra beta, take note. Microsoft announced that Word, Excel, PowerPoint, and other Office apps may have problems with the High Sierra beta; Office 2016 should run, but users may encounter crashes. Office 2011 will not work. Office will have full support of the final version of High Sierra, as Microsoft has clarified in a support document.
Other features
Since High Sierra is a maintenance release, there will be lots of little improvements all over your desktop that you might not even notice at first.
In Notes, you can better organize your information by using a formatted table. Got note you need to access frequently and quickly? Now you can pin it.
Siri has a more natural voice that sounds more like a person rather than a machine.
Spotlight will provide flight information, and can show multiple Wikipedia results when there’s more than one answer to your question.
Get a sneak peek at the new emoji coming to macOS.
In Mail, Search will now use Spotlight to quickly identify top hits, and you’ll be able to split your inbox and your compose window when in full-screen view. Also, Mail has been optimized so it uses less space on your storage device.
When you’re in a FaceTime call, you’ll be able to easily turn a special moment into a Live Photo so you can remember it forever.
There are a bunch of improvements that IT professionals will appreciate, too.
macOS High Sierra FAQ
What is the name and version number of the new macOS? Apple names its macOS versions after California locations. This time, it named the new version High Sierra. The name follows Apple’s pattern of slightly changing the name of the previous version of the OS if the upgrade isn’t considered a big one. (See for example, Leopard and then Snow Leopard, Lion and then Mountain Lion.)
Apple senior VP Craig Federighi joked during the WWDC keynote that the name could be “misconstrued,” but Federighi was reassured that the name High Sierra was “fully baked.”
If you’re into version numbers, then you’ll be happy to know that this one is version 10.13.
When was macOS High Sierra released? September 25, 2017.
How much does macOS High Sierra cost? Apple makes its operating systems free, so macOS High Sierra is a free upgrade for users who have macOS Sierra installed.
From what operating systems can I upgrade to macOS High Sierra? If you have macOS Sierra (the current macOS version), you can upgrade straight to High Sierra without doing any other software installations.
If you are running Lion (version 10.7.5), Mountain Lion, Mavericks, Yosemite, or El Capitan, you can upgrade directly from one of those versions to Sierra. Chances are this will still be the case with High Sierra.
How do I get macOS High Sierra? Apple will make the High Sierra upgrade available in the Mac App Store.
Can I try the macOS High Sierra beta? If you are a developer, you can get a beta of macOS Sierra through the Apple Developer Program. The developer beta is available now.
Apple also has a beta available to the general public, which is now available. Public betas are released on a regular cycle and the betas are free, but come with the caveat that the software isn’t as stable as it would be at release—meaning it could cause problems on your Mac. However, if you do decide to try the beta, you can provide Apple with valuable feedback. The public beta is not the same versions as the developer beta; it’s a few cycles behind.
Learn more about the macOS High Sierra Public Beta, or you can go ahead and sign up for the public beta program online here. You need to make a Time Machine backup before you install the beta in case you need to restore your system.
If you try out the beta and decide later that you don’t want to use it anymore and want to go back to macOS Sierra, Apple has instructions on How to unenroll from the public beta and how to restore your system.
You can continue to participate in the beta program after the High Sierra golden master has been released. You'll get beta versions of the High Sierra updates.

A dozen years ago, when you had to pay for a new macOS version (it was called OS X back then), Apple typically loaded each new upgrade with eye candy that grownups turned off.
In recent years, now that macOS is a free upgrade for everyone, each new version leaves its biggest improvements hidden beneath an interface that looks almost exactly the same as the last version.
Best steering wheel for mac. By naming it macOS High Sierra, Apple is making the same point that it made a few years ago when upgrading OS X from Leopard to Snow Leopard: The new version makes things better more than it makes them different.
What Is The Best Keylogger
Below are highlights worth knowing about High Sierra. For an in-depth look at Apple's new desktop operating system update, read PCMag's full macOS High Sierra review.
Free Keylogger For Mac
1A Brand New File System
High Sierra has a new default file system, APFS. High Sierra-equipped Macs will ship with their disks formatted in the APFS file system instead of the now long-in-the-tooth HPF system. APFS adds increased security and reliability and vastly increases the speed of file transfers. An option lets you format disks so that encryption is built in, not merely applied as it is in Apple's FileVault. When you upgrade to High Sierra, the installer offers to upgrade your disk to APFS during installation. If your Mac is a dual-boot system that has a partition with an older macOS version that can't read APFS disks, you won't be offered the option to upgrade the disk during High Sierra installation, but you can reformat your disk later on by booting to Recovery Mode and using the Disk Utility. For more details, read What APFS Means for You.
2Better Graphics and VR
Apple claims massive increases in graphics speed, thanks to the new Metal 2 technology in High Sierra. Apple also introduced native support for virtual reality. Both of these updates rely on third parties to create compatible software and hardware, so it remains to be seen how it all works out, but the groundwork is all in place now. Note that you'll need enough graphics horsepower for VR, meaning either a high-end iMac or an external Thunderbolt 3 GPU.
3Backward Compatibility
High Sierra runs on iMacs and MacBooks dating back to late 2009, and all other Macs dating from 2010. I installed it on a 2010 white MacBook, a model that was never a speed demon but which seems snappier than ever running High Sierra on the APFS file system. The upgrade process was quick and flawless, despite the miscellaneous old software I had accumulated on that machine over the years.
4Safari Knows When to Keep Quiet
High Sierra won't start shouting without warning. My No. 1 computing annoyance—maybe yours, too—is the experience of listening to music in iTunes, then browsing to a news site where a video window opens automatically and an announcer starts shouting bad news over the music. In High Sierra, Safari automatically blocks audio and video on every site, unless you open a dialog box that authorizes it on a specific page. Finally, you can surf the web without desperately clicking—always too late—on Safari's mute button.
5Safari Privacy Protection
Are you creeped out when ads start showing up in your browser for a product you looked at on Amazon? Safari now tries to block the cross-site tracking data that produces those ads, and you may lose some of that creepy sense of being watched everywhere you go.
6Persistent Website Customization
High Sierra customizes websites so they stay customized. Do you visit sites where the type is too small or too large, or that insist you turn off your ad blocker? You used to have to change your settings each time you visited the page, but with High Sierra the browser remembers these settings. You can also set Safari Reader to display automatically for easier, less distracted reading.
7Editing Features for Photos
The macOS Photos app, after a thorough overhaul two years ago, gets a reorganized sidebar with albums sorted according to media type and quick access to older imports. Photo-editing features include the ability to turn a Live Photo into a repeating loop (like an animated GIF). Editing features in Photos include easy manipulation of color curves and new filters. And you can edit a photo in third-party apps from inside Photos, with any changes reflected instantly in Photos itself.
8Mail Upgrades
This key productivity app gets a more sensible interface in High Sierra. Apple's Mail app—for me, the standout app for managing multiple mail accounts—now supports a split-screen feature that's available when you're running the app full-screen. An option, turned on by default, creates a new message in a split-screen pane instead of a new window, while the inbox remains visible in a pane on the left.
9Notes Tweaks
The Notes app gets small but valuable improvements, such as a pinned note feature that keeps important notes at the top of the list and support for tables in notes, along with the earlier checklist feature. You can also now share notes with contacts for collaboration.
10A Brighter Spotlight
In the latest version of High Sierra, Spotlight illuminates more territory. The Spotlight search engine acts a lot more like Google. You can now type in a flight number and view gate numbers and a flight map, just as Cortana does on Windows 10. If Spotlight can't zero in on the answer, it offers a batch of Wikipedia entries to choose from.
11iCloud File Sharing
Apple iCloud gets advanced file-sharing features that let you send a link to a file via message or mail. The recipient can view or (if you allow it) edit the original file by clicking on a link. You can still send files as attachments, but this method means that your colleagues can always collaborate with you on the latest version of a file.
12Tighter Security
Security is stronger than ever in High Sierra. Apple keeps plugging potential openings for bad guys to invade your system. When I installed a Hewlett-Packard printer into High Sierra, the OS downloaded a driver from HP, but then popped up a warning that it wouldn't install the driver until I went to the Security preference pane and explicitly allowed it.
13What's New in iOS 11
Apple's mobile operating system also got a major upgrade, which affects most Mac users, since they're likely to also be iOS users. For more info on the new version, check out The Coolest Features in iOS 11.
