The latest update to macOS provides support for external graphics card. Apple announced this would hit the OS last June at WWDC and now it’s finally here. The update allows Mac users to increase the graphical processing power through an external graphics card connected through Thunderbolt 3.
Perviously users had to buy an eGPU dev kit from Apple or employ unofficial means to enable external graphics cards, which meant Apple wouldn’t bail them out if something happened. The additional horsepower isn’t needed for general use, but the added graphics cards supercharge Macs for VR, rendering and gaming. Only a handful of eGPUs are compatible with macOS so choose carefully before adding one to your rig.
The 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.
