But with 10.13.4 Apple blocks all Nvidia eGPUs and all TB1/TB2 connectivity, making Apples. Apple demonstrated eGPU connectivity over Thunderbolt 3 with Sonnets eGFX Breakaway Box at Apples 2017 WWDC (World Wide Developers Conference).

My iMac Pro was running great with 10.13.3 and an Nvidia 1080Ti in an AkiTio Node Pro eGPU enclosure. Stay tuned for additional details as they become available. Many people built eGPU rigs on 10.13.1, 2 and 3 and, with some workarounds, they were working great with Nvidia board. The company has also implemented new virtualization and emulation software to ensure that ARM Macs can run Intel-based apps. Instruction caches aren’t coherent with data caches on Apple Silicon, and unexpected results may occur if you execute instructions without invalidating the caches,” a JIT document reads.Īpple has also released a Developer Transition Kit for app makers to work on Apple Silicon hardware prior to a consumer release. “Always call before you execute any instructions from your threads. The Cupertino tech giant is also giving developers other advice amid the switch to Apple Silicon, including on porting just-in-time (JIT) compilers. It’s unknown as to which GPUs will be supported, or if there may be an avenue for third-party PCI-E GPU support going forward. Since high sierra, Apple have officially supported eGPU only for AMD-based or iGPU-based devices. “The integrated GPU in Apple processors is optimized for high performance graphics tasks.” Apple must support Nvidia-based Macbook for AMD-eGPU KIT, No discrimination, NOT can Apple response From 2012 to 2014, even before, Apple produced millions of Nvidia-based devices. I want it for Blender 3D rendering using OpenCL and until 10.13.2 the eGPU wouldnt work at all with it. Some even refuse to load up, including Premier and just crash. “Don’t assume a discrete GPU means better performance,” Apple wrote. As of macOS 10.13.2 no Adobe CS 2018 apps see the eGPU properly and none of them actually use it if they do see it.
APPLE EGPU KIT DRIVER
It is similarly unclear what that means for eGPU support, although that may be more dependent on Thunderbolt 3 and driver compatibility.Ī recent developer support document also advised developers not to underestimate an integrated Apple GPU. Where Apple hasn’t detailed exactly which GPUs will be compatible for the new generation of Macs, it could indicated that an ARM-based version of macOS could also drop support for Intel, NVIDIA and AMD graphics chips.
APPLE EGPU KIT MAC
“Apple Silicon Mac contains an Apple-designed GPU, whereas Intel-based Macs contain GPUs from Intel, AMD and NVIDIA,” said Gokhan Avkarogullari, Apple’s director of GPU software. In a recent WWDC 2020 developer session focused on porting Metal apps to the new architecture, the company made it clear that Apple Silicon Macs will feature customer Apple GPUs. There are still no details as far as price or shipping times are concerned, but those details will likely be revealed sometime after today’s keynote.Some Apple support documentation indicates that Apple might drop support for non-Apple GPUs in its transition to Apple Silicon processors. Not only will Metal 2 offer support for eGPU setups, but Apple will be offering its own Thunderbolt 3 external graphics kit for developers, which will include an AMD RX 580.ĭevelopers will be able to order the Metal 2 developer kit later today with an AMD GPU in the box.
With the Metal 2, such hacks will no longer be a requirement. Using eGPUs paired with an RX 480/580 involved a hack to enable eGPU support, and a hack to enable the RX 480/580 GPUs graphics acceleration. Previously, users who wished to utilize external GPU units had to jump through a few hoops due to it not being officially supported. Apple is partnering with Valve to support SteamVR, along with support for the Unreal 4 engine and Unity. That means that eGPU setups featuring units like the Akitio Node, will officially support AMD’s popular RX 580 GPU.īut not just that, the Metal 2 developer kit will make it possible to connect to VR headsets. Apple has announced that its new Metal 2 Developer Kit, which launches later today, will support external graphics units over Thunderbolt 3.
