Your late-model Mac could get way more powerful soon -- just plug in an eGPU.
Apple promised it would let you tap into the power of an external graphics card with your late-model MacBook Pro , iMac Pro and 2017 iMac . That day has arrived: MacOS High Sierra 10.13.4 now officially supports eGPUs, letting you plug a box containing a desktop graphics card into a laptop or all-in-one PC to drastically up its graphics performance and hook up additional monitors.
Technically, the feature had been kinda-sorta enabled in MacOS since High Sierra first launched, but this latest update brings official compatibility for a host of external GPU enclosures and AMD graphics cards, plus the abilities to hot-swap and/or safely disconnect an eGPU by tapping a button in the operating system.
Just know there are still a few catches right now:
After playing with the Razer Core eGPU and a pair of thin Windows laptops, I'm personally super excited about a future where eGPUs could make traditional desktops obsolete. Official Apple support is a major milestone toward that goal. But there's clearly a lot of work ahead.
