macOS Notes

Sonnet's May 2026 compatibility table limits M-series Macs to non-GPU cards in this enclosure. Apple Silicon does not have an officially supported external-GPU graphics path.

Windows Notes

Sonnet supports the enclosure for eGPU use on Windows 11 25H2 or later. It accepts triple-wide cards up to 345 x 155 x 70mm.

NVIDIA Notes

No native macOS CUDA or supported Apple Silicon graphics path. Any TinyGPU/tinygrad compute experiment requires exact-stack validation.

AMD Notes

The ASUS Radeon AI PRO R9700 fits the published physical envelope, but macOS software support is not implied and must be reproduced before quote.

The manufacturer, model, availability, and final amount are confirmed in checkout or in writing before fulfillment. A replacement is never made silently.
