Description

### 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

ComfyUI should not slow down MacOS 26 Tahoe systemwide

### Actual Behavior

ComfyUI slows down MacOS 26 Tahoe systemwide

### Steps to Reproduce

1. Open ComfyUI on Mac 26 Tahoe
2. Observe system slowness

ComfyUI currently uses an older version of Electron which is slowing down MacOS 26 (Tahoe).
