Apple has released macOS High Sierra 10.13.4, which is hitting MacBook and iMacs around the world as of Friday.

The software update doesn’t include any major features that users will notice visually, but one welcome addition is support for external graphics processors. Whether you’re a gamer or a video editor, that’s something you should definitely appreciate. An eGPU enables underpowered desktops and laptops to harness the capabilities of a dedicated graphics card without the extra bulk. It’s as simple as connecting your Mac to the eGPU with a single cable.

Other than that, there’s isn’t anything too fancy going on. Apple added the ability for businesses and customers to chat within the Messages app. Also, a bunch of privacy tweaks have been implemented. It’s more of a clean-up this time around for macOS.

Here’s the full changelog:

– Adds support for Business Chat conversations in Messages in the U.S.
– Adds support for external graphics processors (eGPUs)
– Fixes graphics corruption issues affecting certain apps on iMac Pro
– Allows jumping to the right-most open tab using Command+9 in Safari
