MacOS Sonoma 14.4 update breaks GPU acceleration on Apple Silicon

Steps to reproduce: Install CUI on MacOS 14.3.x. Update to latest version, 14.4.
Expected behavior: Generation of usable images
Issue: After update, ComfyUI outputs Rothko-esque solid color images (usually cyan or white), unless a ControlNet is used, in which case it outputs a ghostly image of the input on a solid color.

This has been [reported](https://www.facebook.com/groups/stablediffusion/permalink/1337492983582840/) to affect both CUI and other SD UI's since the beta version. However, Draw Things appears to function normally.

I have tried updating pytorch to the latest nightly which did not resolve the issue.

Also of note: "generation" time seems much shorter than before the update, tho the output is garbage.
