On March 29 Apple rolled out the macOS High Sierra 10.13.4 update for compatible Mac computers. The new version is said to improve the stability, performance, and security of your Mac, and all users are recommended to install the software update.

Here is the changelog of macOS High Sierra 10.13.4:

For game lovers, the most significant feature introduced in macOS 10.13.4 could be the native support for external graphics processor (eGPU) on Thunderbolt 3-equipped Macs. Apple promised to enhance the ability last year at WWDC 2017. Currently there’s a limited list of supported configurations, and Apple warmed that eGPUs are supported on MacBook Pro notebooks released in 2016 and later, iMacs launched in 2017 and later, and iMac Pro. Here are some recommended graphics cards:

• AMD Radeon RX 570
• AMD Radeon RX 580
• Radeon Pro WX 7100
• AMD Radeon RX Vega 56
• AMD Radeon RX Vega 64
• Vega Frontier Edition Air
• Radeon Pro WX 9100

Apart from improving users’ game experience, an eGPU can give your Mac additional graphics performance for professional applications, 3D gaming, VR content creation, and more. But note that not all apps support eGPU acceleration.

Along with the release of macOS 10.13.4, the company also pushed out the Security Update 2018-002 Sierra for macOS Sierra 10.12 users, and Security Update 2018-002 El Capitan for macOS El Capitan 10.11 users. These two updates are exclusive for security patches, and 34 known vulnerabilities are addressed in the recent updates.

Meanwhile, iPhone and iPad users can upgrade their devices to iOS 11.3.
