The release of macOS 10.13.4 brings Apple's official external GPU support, however the company recommends certain cases / chassis and cards, except those that some people hope to use.
In a late Thursday support page, the company suggests several AMD graphics cards. These include the Radeon RX 570 and RX 580, the Radeon Pro WX 71
Support is not limited to any specific card provider. As long as the card complies with the reference specification, they can be used in an eGPU package.
The list excludes all maps of Nvidia. Nvidia has the "web driver" for its PCI-E, which is updated after each macOS revision, but that's not enough to run the cards in a single box without using third-party hacks, and even that Can Be Problematic
During the beta process, some of the maps that worked on Apple's first eGPU support test are no longer supported, like the AMD RX 560. Mac owners also need to use Thunderbolt 3, as well as official support for previous versions of Thunderbolt was
Apple notes that people can connect more than one eGPU, although people should use direct connections whenever possible instead of concatenating them. Apple's housing recommendations provide 87W of charging power for the host computer. For 13-inch MacBook Pros from 2016, the eGPUs should always be connected on the left side to guarantee maximum bandwidth. All VR headsets should be connected to the eGPU.
To verify that maps are working properly, users should open the macOS Activity Monitor and then select Window and GPU History. Once a session is over, Apple notices that the new chip icon in the Mac menu bar should be used to separate it.
The macOS 10.13.4 update also included support for business chat in messages and a variety of bugfixes, such as B. for graphics issues that affect apps in iMac Pro.
