Today, I am updating my macOS to Tahoe.  
But then I cannot build my project on Xcode.  
At first, after the update, it is missing the Metal Toolchain. Then I adding it to my Xcode setup and it is fine.  
Whenever I tried to build my project on Xcode, it is always failed.  
Inside this folder path there should be Mac folder or so:  
‘/Users/Shared/Epic Games/UE\_5.5/Engine/Platforms’  
I already try to reinstalled my Unreal Engine version from Epic launcher but it is the same result.  
Something that is even worse is when I created new project from the beginning from my Epic Launcher, the project folder is created but it is missing the Binaries folder.  
I am not sure why this Binaries folder is not created.  
I also tried to manually build the project using this command:  
“/Users/Shared/Epic Games/UE\_5.5/Engine/Build/BatchFiles/Mac/GenerateProjectFiles.sh” -project=“/Users/YourUsername/Path/To/Project/YourProject.uproject”  
but it does not work anymore with this MacOS Tahoe

Can someone clarify or help if you ever have the same issue on MacOS Tahoe?

Maybe you have to change the value of the supported Xcode version, check out this [post](https://forums.unrealengine.com/t/conflict-running-unreal-engine-on-mac-os/2657924/4).
