Unreal engine 5.3, Quixel bridge screen is black. MAC OS.

Hello all,

For those experiencing the Quixel Bridge black tab issue in UE5 (version 5.5) on MacOS Sonoma (or encountering the “failed to restart background service” loop), the problem is related to the library path folder configuration.

How to resolve the issue:

  1. Click on the Profile Icon in Quixel Bridge and select Preferences (refer to Image 1).
  2. Update the folder location to match the folder path used by the Quixel Bridge App (refer to Image 2).

By default, this folder is typically located in the Documents directory with the following path:

/Users/<YourUsername>/Documents

Note that on MacOS, drives are not identified by letters (e.g., C:). Instead, the Macintosh HD drive is represented with a forward slash /.

I hope this helps! I spent some time figuring this out, and I hope this post saves you the trouble.
