Having launched in September of last year, the original macOS Sierra was very well received, bringing better integration between Macs running the software and iPhones and Apple Watch devices.
Apple’s macOS High Sierra, on the other hand, seems to be building onto functionality that’s already in place. So while the list of changes might be shorter than last time, they should nonetheless be received with open arms. Here’s everything we know about macOS High Sierra.
Cut to the chase
- What is it? The 2017 edition of Apple’s Mac operating system, macOS
- When is it out? Available to install as of September 25
- What will it cost? macOS High Sierra is free to download
macOS 10.13 High Sierra release date
Apple unveiled macOS 10.13 High Sierra at the WWDC 2017 keynote event, which came as little surprise, as it's traditional for Apple to announce the latest version of its Mac software at its annual developer event.
But, it wasn’t until September 12 that Apple revealed that the full version of on September 25. There was a developer version of the operating system you could enroll in leading into the final release, but fortunately that’s no longer necessary to take advantage of the latest features found in macOS 10.13.
Instead, simply head over to the App Store on your Mac and it should be featured on the front page shortly, if not already. Otherwise, do a query for macOS High Sierra in the search bar.
macOS 10.13 High Sierra features
These include improvements to Safari – which will now thwart ad-tracking and auto-playing videos – and a more comprehensive Spotlight Search in the Mail App. Moreover, when you’re writing emails, the app now allows split view for the compose window – and it will use up to 35% less disk space as well.
The Photos app has been updated in macOS 10.13 High Sierra as well, with a better sorting tool to boot. All of this is complemented by a new layout, better facial recognition thanks to neural networks, and better syncing across all Apple devices.
Editing tools, too, have seen improvements, in turn making it easier than ever to enhance the quality of your photos without learning the ins and outs of Photoshop or Camera RAW. And of course, you can count on Instagram-like filters being a part of this.
One of the biggest changes that comes with macOS High Sierra is with the file system. It’s ditching the HFS – which Apple has used for around 30 years, and is now using the Apple File System (APFS) instead.
To be exact, APFS is a 64-bit file system that supports native encryption and faster metadata operation. This may all sound a bit techy, but the bottom line is that this will make your Mac feel a lot faster, while also being more secure and more transparent about the nature of your files and folder contents.
The update also brings HEVC, or H.265, video compression to the Mac. Apple claims that this new standard can compress video files 40% more than the previous-generation H.264 standard. The end result will be faster video streams at higher resolutions – ahem, 4K – and smaller video files sizes when stored locally.
VR finally comes to the Mac
One of the biggest bits of news surrounding macOS High Sierra is that it will finally bring support for virtual reality headsets officially. Namely, the and Steam VR will work with Macs running the new OS this autumn.
However, to use such a device, you'll need at least a 5K iMac or MacBook Pro – or, any Mac that can run the new OS with an . Support for such devices will come part and parcel with macOS High Sierra, but won't be an active function until spring 2018.
macOS 10.13 High Sierra compatibility
Fortunately, in the act of creating a macOS iteration that only moderately shakes things up, the barrier to entry didn’t change at all. As long as you’re rocking one of the following Mac models, you’ll be good to go with macOS High Sierra on day one:
- Late 2009 or newer
- Late 2009 /MacBook (Retina) or newer
- Mid-2010 or newer
- Late 2010 or newer
- Mid-2010 or newer
- Mid-2010 or newer
Bear in mind that if you want to take advantage of the High Efficiency Video Coding (HEVC) benefits posed by macOS High Sierra, you’ll need a Mac donning – at the very least – an Intel sixth-generation Skylake processor. That means that, yes, will do just fine.
