Everything you need to know about Apple’s latest desktop OS
As much as the name makes us laugh, macOS High Sierra does a lot right, and although you could find most of its features in last year’s macOS reboot, there are a few notable changes worth talking about. Not only that, but the extent of Apple’s support for macOS High Sierra makes it an important addition to Apple’s widening family of software.
For one, patches were prioritized by Apple for macOS High Sierra to combat the Meltdown and Spectre vulnerabilities recently discovered to have been affecting Intel-based machines across the board since the early 2000s. It wasn’t until January 24 that older Mac operating systems were treated to a similar fix.
As such, it’s clear now that macOS High Sierra is the free update you should be downloading and installing if you haven’t already. Aside from a handful of minor technical issues that will undoubtedly be ironed out in the coming months, it’s a welcome set of refinements to the existing macOS platform featuring a steady flow of sustenance from its creators.
While it does introduce a selection of more comprehensive photo editing tools, a completely overhauled file system and the promise of eventual VR support, most users will continue to use their Macs without noticing much of a difference.
In the meantime, here is everything you need to know about macOS High Sierra.

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, given that it’s traditional for Apple to announce the latest version of its Mac software at its annual developer event.
Yet, it wasn’t until September 12 that Apple revealed that the full version of High Sierra would release just a week and a half later, 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.
Since then, macOS High Sierra has received numerous updates, the latest of which is version 10.13.3. In it, you can expect the usual stability improvements in addition to a fix to a Messages bug that was previously showing texts out of order. Not only that, but for those experiencing a glitch that allowed App Store system preferences to be unlocked without a password, that too should have disappeared in macOS High Sierra 10.13.3.
macOS 10.13 High Sierra features
Despite some Hackintosh users being rightfully worried about the newly enforced security checks on EFI firmware automatically deployed every week, Apple has introduced a number of exciting new features with macOS 10.13 High Sierra.
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, to make matters better, it uses up to 35% less disk space.
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.
Every Mac that’s upgraded to macOS High Sierra will make this files system change automatically with the exception of those sporting Fusion Drives and older HDDs. Likewise, all new Macs will ship pre-formatted for APFS.
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 HTC Viveand 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 external graphics card box attached via Thunderbolt 3. 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 iMac or newer
- Late 2009 MacBook/MacBook (Retina) or newer
- Mid-2010 MacBook Pro or newer
- Late 2010 MacBook Air or newer
- Mid-2010 Mac Mini or newer
- Mid-2010 Mac Pro or newer
- 2017 iMac Pro
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. Unfortunately, that discounts everything released prior to 2015, but on the bright side, everything else macOS High Sierra brings to the table is fair game.
