Black images generated on a Mac Studio with M3 Ultra 256GB RAM

### Custom Node Testing

- [ ] I have tried disabling custom nodes and the issue persists (see [how to disable custom nodes](https://docs.comfy.org/troubleshooting/custom-node-issues#step-1%3A-test-with-all-custom-nodes-disabled) if you need help)

### Expected Behavior

Generate a wide-angle version from a given image.

### Actual Behavior

Generate only black images on a Mac Studio with M3 Ultra and 256GB RAM but work normally on a MacBook Pro with M3 Max and 128 GB RAM with the same workflow and Comfyui settings.

### Steps to Reproduce

Just run the workflow with default settings. It works on a MBP with M3 Max and 128Gb RAM properly but not on Mac Studio with M3 Ultra and 256GB RAM.

### Other

The Sogni app (https://www.sogni.ai/) encounters the same issue of generating black images as Comfyui on the Mac Studio with M3 Ultra and 256 GB RAM, while it works properly on MBP with M3 Max and 128GB RAM. I wonder if this is a compatibility issue with only the Mac Studio with M3 Ultra and 256GB RAM.
