macOS 10.13 High Sierra release date, news and features

null

Until later this year, when macOS Mojave takes over, macOS High Sierra is the OS behind all of the best Macs – so, let’s dive into all the details surrounding Apple’s premier OS.

Now, while it’s seen its own fair share of issues, like password vulnerabilities and other security issues – most macOS High Sierra problems have been patched by Apple, and our time with the OS has been mostly positive. Plus, that new file system and built-in photo editing tools more than make up for any of macOS High Sierra’s launch woes.

Sadly, the major problem that macOS High Sierra has is similar to what faced OS X Mountain Lion when it followed Lion – it introduces a number of new features, but none that really innovate in a major way. However, macOS Mojave looks like it’s going to be one of the biggest macOS releases in recent memory, and will see several key iOS apps like News and Stocks making their way over to macOS after all – we guess Apple fans did want them.

In the meantime, here is everything you need to know about today’s 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 now
  • What will it cost? macOS High Sierra is free to download

macOS 10.13 High Sierra release date

Apple revealed macOS 10.13 High Sierra at the WWDC 2017 keynote, which is no surprise, given Apple’s tradition of announcing 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 release of High Sierra would launch little more than a week later, on September 25. There was a developer version of the operating system you could enroll in leading to the final release, but luckily that’s no longer required to take advantage of the latest features found in macOS 10.13.

macOS 10.13.6, likely the final version of macOS High Sierra, has been released, and alongside a couple bug fixes, it integrates Airplay 2 into iTunes (though you’ll also need to update iTunes to take advantage of it). You can download the update from the Mac App Store now. However, if you’re interested in testing out new features and updates before everyone else, Apple is still supporting its beta program, which will let you download and install macOS Mojave now.

At the same time, it now uploads all Messages to the cloud and replaces iBooks with the newly rebranded ‘Books’ app. There’s also been a sweet smoke cloud wallpaper added across all systems that was formerly available only on the iMac Pro

For everyone else, the newest rendition of macOS as a whole is still 10.13.5 High Sierra, as we await the much-anticipated macOS 10.14.   

macOS 10.13 High Sierra features

Beyond the Hackintosh users being reasonably worried about the newly enforced security checks on EFI firmware automatically implemented each week, Apple has revealed a number of awesome new features with macOS 10.13 High Sierra. 

These include improvements to Safari – which will now stop ad-tracking and auto-playing videos in their tracks – and a more expansive Spotlight Search in the Mail App. Additionally, when you’re composing 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 accompanied by a new layout, better facial recognition thanks to neural networks, and improved 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 has been upgraded to macOS High Sierra will receive these file system updates automatically with the exception of those sporting Fusion Drives and older HDDs. Similarly, 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. Unfortunately, this comes with the caveat of Apple’s confirmation that 32-bit apps will be discontinued in later versions of macOS High Sierra.

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 Vive 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 external graphics card box attached via Thunderbolt 3. Support for such devices comes part and parcel with macOS High Sierra, but won't be an active function until spring 2018.

The good news is that macOS High Sierra comes with a helping of refinements to its graphics API that make up for the scarce GPU support. Metal was a step forward for hardware-accelerated 3D graphics, but with Metal 2, Apple promises less strain on the CPU as well as proper machine learning and better Xcode profiling/debugging in macOS High Sierra.

Perhaps more important, though, is the fact that MoltenVK was recently brought to Mac by Khronos Group. An implementation of the open-source Vulkan API, it’s said to bring frame rate gains of up to 50% in Dota 2. As it’s cross-platform, too – being supported by Windows and Linux as well as Apple’s devices – MoltenVK is likely to be more widely adopted by creators.

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:

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.
