The macOS High Sierra update delivers new features to your Mac and upgrades some of the existing features from macOS Sierra so that you can do more with the computer you have. With the macOS 10.13.14 you finally get full support for using an external graphics card with your mac.
The full macOS High Sierra release arrived in September, but came with many problems. With macOS 10.13.4 Apple fixes a number of issues and includes security updates as well as full eGPU support for the 2016 and newer MacBook Pro, 2017 iMac and the iMac Pro. Keep in mind the macOS High Sierra install takes a while to complete if you are coming from macOS Sierra.
Apple’s macOS High Sierra comes as a free upgrade to all Apple computers that support macOS Sierra. The High Sierra update is packed full of important upgrades that will allow you to do more with your photos, browse the web better and with the right computers even explore Virtual Reality on your Mac.
Under the hood, Apple is switching up the way your Mac stores files to supercharge the speed of copying and moving files and taking new steps to better secure your privacy while browsing online.
If you have a MacBook with limited storage, and let’s be honest most of us do, you’ll benefit from new space saving techniques that will keep your videos looking great, but that will take up less space. It also helps your Mac work better with your iPhone and iPad on iOS 11.
These are the new macOS High Sierra features and how they compare to macOS Sierra when applicable.
Upgraded Power and External GPU Results
Under the hood, Apple adds Metal 2. This is a new way for your Mac to gain power and abilities by tapping into the GPU in your MacBook.
This is part of what allows the Mac to use machine learning to identify things in your photos and much more. It's the power behind support for Virtual Reality on Mac and it is essential for the new external GPU options.
With macOS 10.13.4, you can plug newer Macs into a USB C Thunderbolt 3 dock with an external GPU that unleashes more power when you are at your desk.
Whether you need better gaming support at home or you simply need more power for special effects, rendering, editing and other tasks -- this is an exciting addition to macOS High Sierra.
