Installation on an external SSD fails with following error in logs \>  
“Failed to execute startup-script: /Applications/ComfyUI.app/Contents/Resources/ComfyUI/custom\_nodes/ComfyUI-Manager/prestartup\_script.py / type object ‘datetime.datetime’ has no attribute ‘datetime’”

Running the downloaded Desktop app from the internal SSD to set up on external SSD.

Also \> During setup there is an alert that the destination directory already exists when it is a newly created empty folder.  
\_\_\_ **UPDATE**  
When I install using the directory defaults - it works. So instead of selecting an external directory during setup I went with the default and Symlinked the model folders to my extrernal SSD storage. Nevertheless - it should be possible to select custom directories for model storage and ‘input/oiutput’ folders.

I have the same issue with ComfyUI Manager and get the datetime error. Any update on this??

Please try with custom nodes disabled - you can check this by temporarily moving them to another directory.
