I’m using macOS Sonoma 14.2.1 and Unreal v5.3.2-29314046+++UE5+Release-5.3. I am having a similar issue and changing the Library Path doesn’t work. When I try and log into Quixel Bridge using the plugin via Unreal Engine, I get the following error:
request to [Uh oh! Nothing here!] failed, reason: self signed certificate in certificate chain
In order to retrieve Metahuman assets, I’m having to export the .mhb files and send them to a teammate who has a Windows machine and can log in.
