Mac Pro (Late 2013, plus mid-2010 and mid-2012 models with recommended Metal-capable graphics card).

The following Macs are compatible with macOS 10.14 Mojave:

Some readers may want to read my enterprise guide to upgrading to macOS Mojave here. You may see some short-term sluggishness while the OS moves into your system, this is normal and usually passes quickly - see it as the hardware/software equivalent of rearranging furniture and unpacking the boxes when you move house.

Once you do upgrade, make sure to visit the App Store to upgrade your applications. IDG Before you upgradeĭon’t just rush into the upgrade always back up your system first. Take a look at 10 macOS 10.14 Mojave secrets for more of these. I’ve also provided a little help to get you started using those new features on your upgraded Mac. Not every feature made it into this review. I’ve looked at each one of the new features in a little more depth below. There’s a lot to be said for the flagship features within this OS:

This is a good upgrade and (assuming no unexpected disasters), I see no reaon not to install it. It seems quite clear that Apple’s focus on making existing features work better across its platforms is an investment that benefits us all. I’ve been impressed at how the OS seems so much speedier in use. I’ve encountered very few bugs - some third-party apps were a little unstable at the beginning of the test period, but it has been a long time since I encountered anything particularly egregious. I have been using it on my Mac for all my work. I’ve been lucky enough to have used Mojave for months. It’s fast and mostly familiar - you should be flying through your tasks within a few minutes of installation. Readers interested in further transcoding details are advised to watch Apple's dedicated HEVC codec video presentation.Apple’s macOS 10.14 Mojave is available now, and after months of using it, I think most Mac users should upgrade if they can. To check if your device's camera is capturing video in HEVC, go to Settings -> Camera -> Formats, and ensure the 'High Efficiency' option is selected.Īll iOS devices running iOS 11 and all Macs on High Sierra will support HEVC playback, with encoding/decoding hardware acceleration on newer iOS devices and the latest 2017 Macs offering faster performance combined with less battery drain. To capture and encode video in the HEVC format, iOS devices need to have at least an A10 Fusion processor, so owners of iPhone 7 or later and 2017 iPad Pro are fully able to take advantage of the standard.

At the same time, transferring high-resolution video files between devices and over networks will require significantly less bandwidth, a key advance considering new 4K iTunes content launched for the new Apple TV 4K. While results vary depending on the type of content and the encoder settings, videos encoded in HEVC typically exhibit fewer compression artifacts and offer smoother playback than videos encoded using AVC.Īccording to Apple, HEVC can compress 4K video files to up to 40 percent smaller file sizes than AVC without losing quality, which means users who upgrade their devices to iOS 11 and macOS High Sierra will be able to take the same high-quality videos without using up as much storage space. To put that another way, a HEVC video file offers significantly better visual quality than an AVC file of equivalent size or bit rate. The HEVC standard enables a video to be compressed into a file that is about half the size (or half the bit rate) of H.264 / AVC. (You can learn more about HEIF here.)Īpple's decision to adopt HEVC basically means two things - higher quality video and better compression rates. The HEVC video format has been in existence since around 2013, and HEIF is the still-image version of the standard that both iOS 11 and macOS High Sierra also support. High Efficiency Video Coding (HEVC), also known as H.265, is a next-generation video compression standard developed by a group of encoding experts called the Joint Collaborative Team on Video Coding. So why has Apple adopted the HEVC format, and what difference will it make to the end user? With the arrival of iOS 11 and macOS High Sierra, Apple is supporting a new video format called HEVC, which replaces the previous standard most commonly used on Mac and iOS devices, namely H.264 / AVC.
