macOS High Sierra Features

macOS gets the yearly bump in features, as you would expect with a ‘minor’ name change to High Sierra, it is more a bug hunt with minor feature additions. Here are some of the highlights.

Autoplay blocking in Safari

Finally for Safari users, when visiting those sites that like to just start playing video and audio by default, you will no longer have to stop them. Safari is going to do it for you until you press play, this should also help with battery life and bandwidth.

Intelligent Tracking Prevention

Thanks to machine learning macOS will now do what it can to help prevent you being tracked all over the Web, another hopeful win for privacy.

Always-On Reader Mode in Safari

In Safari there is now the option to have on by default the reader mode which strips out things like adverts.


Mail will now support the split view, this means you can have the mail application one one side of the screen and the email being composed on the other, no more overlapping or generally annoying interactions with mail whilst writing new messages.


Printing services are being opened up to 3rd parties for more options with books and other printed material. Name data from facial recognition will now also sync across devices, no longer will it be locked in on a particular device.

This version of Photos is also incorporating a lot of the features that will be appearing in the iOS 11 version later in the Fall, for example, the new loop and bounce effects.

Media Support

H.265 video will now be supported, this is a newer improved version of H.264 with better file sizes and compression. Virtual Reality is now supported by Metal 2 and major engine creators like Steam, Unity, and Unreal will be directly supported on the Mac platform.

System Changes

The default file system for macOS High Sierra will be the new APFS (Apple File System) which made its first appearance on iOS 10 devices. Along with that, this is the last version of macOS to support 32bit applications.

I am sure there are other changes that will be discovered over time as we get closer to the final release in the Fall. Apple stated that a goal of this real is to improve stability and bug fixes. I think when it comes down to it, we would all prefer that over some throw away features thrown in just to make a new release.
