Check if your Mac can run macOS High Sierra: Apple's cutoff for iOS updates can be a little brutal, but on the macOS side of the fence, if you're already running macOS Sierra you're pretty much set for compatibility.
So if you're using Macbook or iMac, we strongly recommend you to download macOS High Sierra. Launch the App Store from the Applications Folder, and search for macOS High Sierra. However apart from the various new features and improvements, there is one feature of High Sierra that could make it worth the update. The free update comes with a slew of new functionality that enhances a users' experience, such as the new Apple File System (APFS), support for High-Efficiency Video Coding (HEVC), Metal 2, Core ML developer framework, and support for Virtual Reality.
The update brings some functional and cosmetic changes to numerous core apps in macOS such as Photos and Safari, but much of the real changes are coming under the hood.
Apple's team will be at work on a new patch and - as detailed on its support page - the High Sierra OS fixes a number of other security issues.
However, for just $99 a year, attackers could join the Apple Development Program, which would allow them to sign apps with embedded functionality to steal passwords.
The Live Photo option blends images and videos together to create a short moving picture when you take a photo. This is according to an email sent by a MacRumors reader to Apple's software engineering chief Craig Federighi, who responded by saying that support for APFS on Fusion Drives will arrive in a future update. Not only you end up being on the latest and greatest version of an operating system straight from Apple, but you also retain every single setting including your files. Here are some instructions on how to get iOS 11, while you're at it. It's macOS at its highest level yet.
Elsewhere, a Safari update makes it easier to block auto-playing videos by default, enables reading mode wherever available and adds intelligent tracking that keeps ad providers from following you around the web. The biggest of these is a heavier focus on VR, with heaps of new support for SteamVR, which is now being optimised by Valve to run on Macs.
