Author: LoRA Time: 10 Mar 2025 1015

ComfyUI Desktop is a complete desktop application officially launched by ComfyUI for running ComfyUI.

Currently only supported:

Windows systems with Nvdia GPU (AMD GPU is not supported)

MacOS (Apple Silicon chip)

Since this version is still a beta version, there may be some problems. If you are not a user who likes to try and repeatedly toss, it is recommended that you choose the official portable version or Qiuye integrated package to run it more friendly to native Chinese language users.

After double-clicking the corresponding dmg, drag the corresponding software icon to the Applications folder to complete the installation package

If your icon is in the same state as the one I pictured above, with a transparent forbidden symbol, then I'm sorry your Mac is not compatible with this version

Step 2: Start the ComfyUI Desktop Setup program and start initializing the installation

After completing the first step, your Windows desktop/system menu Lanchpad will have a shortcut to ComfyUI Desktop. Click Run to start the relevant installation of ComfyUI Desktop

In this step, you need to select the installation location of ComfyUI Desktop and create content in the corresponding folder.

Python running environment

ComfyUI Desktop related files

This step will take up about 15GB of disk space

Please make sure your hard drive has sufficient space left

If you can choose SSD installation to accelerate model loading and software running (personal recommendation)

Refer to the screenshot below to select the location you want to install

If you have not installed the corresponding installation, you can ignore this step. If you originally have a ComfyUI installation package, such as ComfyUI_windows_portable, the official portable version, you can choose whether you need the migration function, and the following content will be processed.

Linking to the existing model file location (just referring to the corresponding model address in ComfyUI Desktop, and will not copy the model resources to cause unnecessary space to be occupied)

Migrate user settings files

Migrate your workflow files

Migration content that is not supported for the time being

Custom nodes (plug-in)

In the following interface, select the installation location of your ComfyUI, such as D:ComfyUI_windows_portableComfyUI. Note that it is the ComfyUI directory, so that the program can successfully link the corresponding model and related user resources.

In this step, the preferences provide two options, you can choose as needed.

First option: Whether to enable automatic update of ComfyUI Desktop

The second option: Use analysis, mainly collecting some anonymous usage data and non-sensitive data to provide it to development, which is used to help ComfyUI Desktop make better improvements

Step 5: Initialization of ComfyUI Desktop Python environment

This step is mainly used to install the Python environment necessary to run ComfyUI. If the installation goes smoothly, you will enter this step. This step is automatically executed by the program.

If it doesn't go well, you'll be the same as the screenshot below.

It was successfully installed by replacing the VPN during the subsequent installation. Since you need to set up a python environment during the installation process, you need to access Github Release to get the Python version. If you have installation failure problems in these countries or regions with limited resources, it is recommended to use a VPN or check network problems at this time.

On the screenshot, you can see Unable to start ComfyUI (cannot start ComfyUI). At this time, you can choose Open Logs (open log file), and feedback the corresponding screenshots and log files to the official forum. Click Report Issue. You can jump to the feedback section of the official forum. Remember to submit screenshots and logs to facilitate the official to better locate the problem.
