Hi I'm trying to use control net on comfyUI but having trouble generating image with the error "No module named 'mac_specific'"

Research direction

Start at custom_nodes/ComfyUI_tagger/modules/devices.py, where the traceback reaches the missing mac_specific import, and follow how it is loaded through latent_preview.py, nodes.py, and execution.py. Reproduce the reported control-net generation path in the stated environment; done means KSampler completes without the import error and image generation succeeds.
