what I did was install the regular unreal and the quixel plugin then go to the location where the plugin was installed.
/Users/Shared/Epic Games/UE_5.0/Engine/Plugins/Bridge/ThirdParty/Mac/node-bifrost.app/Contents/MacOS/node-bifrost
Copy the node-bitfrost file and replace the one from source.
it’s still hacky. the plugin open and download the metahumans but the add button doesn’t work so I have to go to the download folder and copy the assets manually to my project.
it work but I wouldn’t recommend it for people that depend on it all the time to follow tutorials like I do I put up with.
