Script for easier install on mac apple silicon / m1 / m2 / m3

[jonathanstanley]

Background: coreML tools are needed to have reasonable speed on a mac. but, the install process for comfy + manager + coreml tools is quite finicky.

After fussing with it for quite some time, I just went ahead and scripted it so the entire process is one command. (if you save the code below as comfy.sh, then the command would be zsh comfy.sh from the folder in terminal

#!/bin/sh

# install homebrew https://brew.sh/
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

# install python v3.11
# 3.10 is the minimum for coreML tools - https://github.com/aszc-dev/ComfyUI-CoreMLSuite/issues/37#issuecomment-2042594570
# 3.12 drops imp which is required by coreML tools - https://stackoverflow.com/a/77281165/4481226
brew install python@3.11

# install git
brew install git

# copy comfyui files
git clone https://github.com/comfyanonymous/ComfyUI comfyui

# goto comfy folder
cd comfyui

# venv per https://packaging.python.org/en/latest/guides/installing-using-pip-and-virtual-environments/
python3.11 -m venv .venv
source .venv/bin/activate

# install pytorch https://developer.apple.com/metal/pytorch/
pip3.11 install --pre torch torchvision torchaudio --extra-index-url https://download.pytorch.org/whl/nightly/cpu

# install dependencies
pip3.11 install -r requirements.txt

# install comfyui manager
(
    cd custom_nodes
    git clone https://github.com/ltdrdata/ComfyUI-Manager.git
    cd ComfyUI-Manager
    pip3.11 install -r requirements.txt
)

# install coreml tools https://github.com/aszc-dev/ComfyUI-CoreMLSuite
(
    cd custom_nodes
    git clone https://github.com/aszc-dev/ComfyUI-CoreMLSuite.git
    cd ComfyUI-CoreMLSuite
    pip3.11 install -r requirements.txt
)

#start
python3.11 main.py

Tried to run your steps but I get the following error.

File "/Users/user/comfyui/main.py", line 134, in
import comfy.utils
File "/Users/user/comfyui/comfy/utils.py", line 40, in
from numpy.dtypes import Float64DType
ModuleNotFoundError: No module named 'numpy.dtypes'

Could you tell which numpy version you are using for this setup?

I recently installed ComfyUI and used Python3.12. Below are my commands. They replace the original thread's instructions between "# venv" and "# install dependencies". I use uv to manage Python virtual environment.

# Install uv
brew install uv

# Where you git clone the project
cd ComfyUI

# Create a virtual environment using uv
uv venv

# Install PyTorch (nightly CPU version) per https://github.com/comfyanonymous/ComfyUI?tab=readme-ov-file#apple-mac-silicon
uv pip install --pre torch torchvision torchaudio --extra-index-url https://download.pytorch.org/whl/nightly/cpu

# Install additional project dependencies
uv pip install -r requirements.txt

# Run the main ComfyUI app.
uv run main.py

Note that when you install custom_nodes, you also need to install its project dependencies with uv.

cd ComfyUI/custom_nodes
git clone https://github.com/ltdrdata/ComfyUI-Manager.git
cd ComfyUI-Manager; uv pip install -r requirements.txt

If anything goes wrong, make sure your Python version is 3.12. See how to configure Python version with uv at https://docs.astral.sh/uv/concepts/python-versions/

Need help in running comfyui on Mac m4.

I was experiencing similar issues to shubham805 and TjitseDeVries - Good news guys, the solution was right here in this repo all along.

Quite a few important additions have been added to the 2.8.0 nightly build in regards to apple silicon and it would be lovely to see this on maybe the dev branch of comfyui so more apple folk get to take advantage of workflows like this: https://old.reddit.com/r/comfyui/comments/17q3mov/three_3_sampling_steps_is_all_it_took_for_these/
But unfortunately on version 2.6.0 of pytorch it throws this error (along with a bunch of others) on apple silicon: aten::_linalg_solve_ex.result (as tracked here pytorch/pytorch#141287)

For the solution?
As described here #6479 ; it's a numpy version issue, so if you upgrade numpy to 1.26.4 (not 2.x) then it should press on. At least it did so for me, I was having the same issue, installing and reinstalling comfyui and python and pytorch over and over again, but now I am happily running pytorch 2.8.0 nightly, even on python 3.10, and that's nested inside Stability Matrix as well even.

Now if I could only get some sort of use out of the Core ML tool's nodes that'd be nice but it seems like that's broken.
