How to Install ComfyUI Mac (M1/M2/M3): Step-by-Step Guide

[@mibesto8039]

Thanks for this concise and very helpful guide. I'm a total dweeb when it comes to working in the terminal, and your instructions made everything simple and straightforward. I still have so much to learn, but your video was the most helpful one I found to quickly and correctly load Comfy UI onto my MacBook Pro with an M1 processor.

[@PromptingPixels]

Thanks so much for the kind words! If you have any other questions, don't be a stranger - drop them in the comments/Discord/website etc and I'll try my best to get back.

Awesome - try to actively cut the fluff in the videos as much as possible. Thanks for watching!

[@marcosansalone]

I'm a bit lost, at 3:13 you start doing stuff and is not clear. What is exactly the code you are writing in the terminal? I can't replicate that.

he saved the text in visual studio to Downloads folder and named it torch-test.py and ran it in terminal

[@henriquematias1986]

i think extending more on where to download, how to download, what is a LORA, etcs, would be a great continuation for this video. I'll check if there anything on your channel regarding that! thanks a lot.

I get an error when trying to install conda 2:04 Could not solve for environment specs The following packages are incompatible ├─ pin-1 is installable and it requires │ └─ python 3.12.* , which can be installed; └─ torchvision is not installable because there are no viable options

[@HPMichalke]

Thank you so much for your tutorial! that is a great starting point

[@daancouzijn4626]

I'm lost at the step on 02:40. I've copy/pasted the code python script in Visual Studio Code and when I run the test in terminal, it says "[Errno 2] No such file or directory". Even though it is installed. What am I doing wrong?

[@PromptingPixels]

Sorry - was away for a bit. Hard to diagnose on a comment - but the error suggests you arent running the command in the right directory. For example, in terminal you often start at the root directory (i.e. typically your home folder - often the users name). But if you saved the script in downloads, documents, etc. you would need to navigate to that directory in your terminal window to run the script. Make sense? If not - chime back in or write a new comment so i dont miss it.

[@xxagonzxx]

@@PromptingPixels Could you elaborate further on this? I want to fix this but this is so niche i'm afraid I won't be able to find help.

This video was super helpful, thank you for the explainer and step by step.

Happy to hear it did well for ya! Have fun now with all the workflow nodes - it can get a little messy!

[@laurenthenry]

Hello ! Thanks a ton for the tutorial. Worked like a charm. Question though : if we close the tab and close the terminal window. Is Comfy UI closed ? Or is it still running in the background and we need to enter a cmd in the terminal to kill it ?

[@PromptingPixels]

Howdy! Closing terminal will close the processes. Cmd+c in terminal also works to shut it down more gracefully.

[@susanguo7578]

Thank you so much for your tutorial! It's really helpful.

[@seis6-r8u]

great tutorial thanks! could you recommend a Mac setup similar to having a desktop pc with a rtx4090?

[@Rachelcenter1]

4:07 you lost me here because I dont have any terminal experience and you're linking it to some tutorial that you have on your computer but havent instructed us to put on our computer. I had downloaded comfy ui yesterday and had all kinds of errors so I'm trying to watch your tutorial instead and when I try to clone the repository into the place I had it installed yesterday, it tells me "fatal: destination path 'ComfyUI' already exists and is not an empty directory". Surprised this line of code doesnt just write over the current directory I already have.

[@michaelpatrignani7533]

Hi, i have a problem. Is the first time I use ComfyUI. When I shut down Mac, when I restart it, how can I open ComfyUI. When I open prompt and copy the line (python main.py --force-fp16) don't work... "python: can't open file '/Users/michaelpatrignani/main.py': [Errno 2] No such file or directory" was the error message.

[@PromptingPixels]

So sorry i am late on replying. Based on your error you need to run that command within comfyui directory (it appears you are running it in your home directory). In other words, you'll want to do this: 1. Open terminal 2. Navigate to the comfyui directory (i.e. cd tutorial/comfyui/) - or you can open the terminal and drag and drop the ComfyUI folder onto it and press enter. Your terminal should look something like this: ``` (content-ai) shawn@Shawns-MBP ~ % cd tutorial/ComfyUI (content-ai) shawn@Shawns-MBP ComfyUI % ``` 3. Run the command: python main.py --force-fp16 Let me know if this works.

Thank you for the video. The topic is completely new to me and I would like to make AI Video Avatar for my website with my face, multilingual etc.. Would I be on the right track with this tool? Thank you for help and answer.

[@PromptingPixels]

Yeah, for short form videos ComfyUI can be used. In particluar you'd want to look at LivePortrait: github.com/kijai/ComfyUI-LivePortraitKJ Otherwise, for general AI videos take a look at Hunyuan - github.com/kijai/ComfyUI-HunyuanVideoWrapper. Hope that helps!

Thank you for coming back. I will have a look into this.

[@yomi0ne]

thank you, very concise tutorial

[@jippalippa]

Excellent tutorial; thanks! Generally speaking, have you found the experience on mac stable enough? I'm asking as automatic1111's implementation didn't always work properly on macOS (M1 Ultra).

[@PromptingPixels]

Honestly, for just basic txt2img or img2img tasks, I find that a Mac can work just fine. However, for anything labor-intensive (such as controlnets+loras, animatediff, etc.), I think it's best to rely on a Windows or Linux machine with a dedicated GPU, as the Mac isn't nearly as performant. If you're having app issues, I recommend checking out WebUI Forge (github.com/lllyasviel/stable-diffusion-webui-forge) or DrawThings (drawthings.ai/), as they might be a bit more stable - especially the latter of the two.

[@AlexK-w7g]

I'm a complete newbie to all of this and I just couldn't install it properly. I tried 5 different tutorials and each time i ended up with the same result. Comfyui starts but ckpt_name is unclickable. Then i used the help of chatgpt to uninstall and clean up, and do it all over again. I tried homebrew 3 times as well. Any sugestions? I've killed many, many, many hours doing this.

Hi, I installed ComfyUI and installed the checkpoint. But when I run the queue, there's a popup said that "Error occurred when executing IPAdapterModelLoader: Weights only load failed. Re-running torch.load with weights_only set to False will likely succeed, but it can result in arbitrary code execution.Do it only if you get the file from a trusted source. WeightsUnpickler error: Unsupported operand 60" Ive tried updating comfy, downloaded the nodes directly from repository and so on. Cant find any info on this error." Hw do I resolve this? MY checkpoint is "v1-5-pruned-emaonly.ckpt" that I downloaded from hugging face

[@VincenzoCosenza]

I'm thinking of buying a mac mini. How much RAM do you suggest for generating images?

[@anokhatv7829]

Loved the video, but can someone explain the "Cloning the ComfyUI Repo" part. Still stuck there. I'm new to macbook

[@PromptingPixels]

Cloning is the same as copying it to your hard drive. There are a couple ways you could do this - either with the `git clone` command which was presented in the video. Or under that same box you could download the zip of the repo and then just extract it to your preferred location on the hard drive. Downside to this approach is that you can't perform a `git pull` command to update the repo when the author publishes updates to the repo. Alternatively, if you are having a hard time getting ComfyUI to work on your machine, Pinokio (pinokio.computer/) is super easy and offers a 1-click installer.

Are u be able to generate video on Mac with comfyUi?

[@PromptingPixels]

Hey there - just got around to testing this. At first I was getting an MPS error like you had mentioned in your other comment. However, this Reddit post provided some insight (www.reddit.com/r/StableDiffusion/comments/174xjxa/animatediff_mac_is_it_possible/) booted it with the following flags: python main.py --force-fp16 --use-split-cross-attention --normalvram And was able to successfully generate a very short 16 frame video at 21 seconds per iteration (5 minutes total). Here was the exact workflow I used to achieve this: promptingpixels.com/wp-content/uploads/2024/02/animatediff-mac-comment-reply-yt.json To note, was testing on an M1 Mac 16GB Ram (so should be able to work on your machine as well).

I used the M1 Max with 32GPU and encountered significant performance issues while generating images and unable to generate videos. The GPU was running at 100% capacity and the process was very slow. Based on this experience, I don't believe that the M1 is suitable for AI generation.

[@yourenotallowed7494]

All these AI programs as well as 3D softwares are optimized with NVIDIA CUDA cores. That’s why you’ll find significant performance issues on Mac. Mac GPU would take up to 200 secs to generate an image while an RTX 4090 would take 6 seconds…

Then either /r/stablediffusion or other videos that other creators have contributed to here on KZbin.

Thanks. Yet I can't help but notice that following IRS form instructions bear a striking resemblance to installing stuff like this. And the constant dependence upon interpreters like Python and scripts will only lead to underperforming software. Maybe someday someone will create a generative AI program that can be downloaded as a compiled program that makes full use of Apple Silicon and Metal.

[@PromptingPixels]

Definitely agree that it does feel overly complicated at times? However, I think a year from now we'll get more and more simple one-click install files that are much more beginner-friendly akin to Diffusion Bee and Draw Things. Yeah, it would be great to see more performant diffusion models on the mac. The text generation models seem to perform quite well - even folks getting Mixtral8x7b running on their machines with just ample RAM and no dedicated GPU.

But the most frustrating thing is, you get to the end of the video and then he just says: Yeah and then copy your model over from SD WebUI. Not a word about how to get a model if you don't have one!!!! And it is not easy, just before typing this I tried to find out and gave up for now.
