Apple promised it would let you tap 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.with your late-model
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:
- Nvidia support is nonexistent. Apple only supports AMD graphics cards right now.
- You'll need to plug in an external monitor to see the benefit.
- According to the eGPU experts at egpu.io, performance on MacOS is far, far worse than with the same eGPU running on Windows. (Search that page for "The Ugly" to see a chart depicting just how much worse.)
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.
