• [X] I have searched the existing issues and checked the recent builds/commits

What happened?

I get this error both when installing on an external hard drive, and when installing on the Macbook then moving the directory the external drive.

Steps to reproduce the problem

1. Run the installer

I have no problem running vanilla stable-diffusion-webui from an external HD.

same issue here, tried several tipps from here but those didn't resolve it for me https://github.com/AUTOMATIC1111/stable-diffusion-webui/issues/1120 am yet to try it but this could be interesting https://discuss.python.org/t/venv-not-function-properly-in-macos-within-an-exfat-disk/26145 ok i'm running into another problem now but this one is solvable with the linked method

This should be fixed in 20230913_experimental, please let me know if there are any further issues.

didnt try the fixes above again but on its own, it still throws the same error (tested with linked version, installer)
