MacOS Update 10.13.4
Now the Apple macOS has the power to give external graphics card support with MacOS Update 10.13.4. This update allows Mac users to increase the graphical processing power through an external graphics card connected through Thunderbolt 3. This really gonna boost graphical power without any harm to the Apple Mac authenticity.
As we have seen previously if users have to use external graphics, he has to buy eGPU dev kit from Apple. Using it unofficially means jailbreak Apple’s product. The inbuilt graphics isn’t capable to run some high-end games and Video rendering. But with the use of compatible eGPU, AMD graphics will supercharge your Mac for high-end use.
(Nvidia is not officially supported)
MacOS new feature comes from the High Sierra 10.13.4 Combo Update which also adds Business Chat in Messages, a new iTunes and a super handy feature to Safari in which users can jump to the right-most open tab by using Command+9.
This new macOS release only supports displays which are directly provided by a GPU or via AirPlay. Actually, Apple has restricted GPU support to the ports that directly connect to the GPU. This means versions of Apple macOS after 10.13.3 will only support the single 4K HDMI port on the dock which uses Display Port over USB-C technology (which is directly GPU connected).
The second and third displays on the dock — the DVI and 2K HDMI ports using Display Link technology — will no longer function.
Windows and Chromebook computers are not affected and will continue to work as usual.
