text: Title: Wan model is not working in MacOs if scheduler is `uni_pc`
  Body: ### Expected Behavior
  
  A normal video output 
  
  ### Actual Behavior
  
  https://github.com/user-attachments/assets/66051ca7-ccd2-4fb9-a186-a9bf4e974772
  
  ### Steps to Reproduce
  
  I was trying to use Wan 2.1 model in Comfy in my macbook pro (M2). And use the example workflow from [blog examples](https://huggingface.co/Comfy-Org/Wan_2.1_ComfyUI_repackaged/blob/main/example%20workflows_Wan2.1/image_to_video_wan_480p_example.json).

  However, I found that I could fix it after I changed the KSampler sampler name to euler or euler-ancestral and ~KSampler scheduler to normal~ (Edit, it is not important).
